Abstract:
Self-weight of a structure comprises a major portion of the overall structural load which causes conservative structure design. Reduction of structures’ self-weight is an active area of research today. One of the options is to use lightweight concrete and no-fines concrete is one of its types. This type of concrete is made with coarse aggregates, cement, and water. From the density point of view, it is the lighter concrete compared to normal weight concrete but it exhibits less strength. Normally no-fines concrete is manufactured with uniform size aggregates. The performance of no-fines

AbstractIn order to research the influence and the function mechanism of calcium formate and defoaming agent on the compressive strength of cement-based grouting material with low water-binder ratio at different ages, quadratic polynomial regression models were established by RSM, and the mix proportion was optimized. The function mechanism of additives was analysed by macroscopic mechanical properties and microstructure. The results indicated that the response surface method is scientific in optimizing the mix proportion of cement-based grouting material. The optimal mix proportion was obtained as fallow: the calcium formate was 0.64%, the water-binder ratio was 0.21 and the defoaming agent was 0.26%, with taking 1d, 3d, 28d compressive strength as the optimization objective. Calcium formate is highly significant for the early compressive strength of cement-based grouting materials with low water-binder ratio, while the water-binder ratio and defoaming agent are highly significant for that of the middle and late period. Calcium formate promotes the formation of CSH gel and $$\mathrm{Ca}{\left(\mathrm{OH}\right)}_{2}$$ Ca OH 2 crystallization in the early period, and the defoaming agent can effectively reduce macropores. The results can provide an optimization method for the mix proportion design of cement-based grouting material and a theoretical reference for its mechanical properties.

AbstractIn order to improve the strength and permeability of coal gangue pervious concrete, an optimized mix design was conducted. An orthogonal experiment was employed to study the variations of compressive strength and permeability coefficient of coal gangue pervious concrete under the influence of aggregate particle size, water-cement ratio, designed porosity, and dosage of permeable admixture. After obtaining a relatively optimal mix proportion, further discussions were carried out by restricting the values of compressive strength and permeability coefficient to determine the appropriate range for the excess paste content ratio, total porosity, and effective porosity, resulting in the determination of the optimal mix design. Results indicated that the compressive strength reached its maximum at an aggregate particle size of 9.5–16 mm, with minimal impact on the permeability coefficient. As the water-cement ratio increased, the compressive strength gradually increased, while the permeability coefficient slightly decreased within the range of 0.25–0.29, and decreased by 60% within the range of 0.29–0.31. With the increase of designed porosity, the compressive strength gradually decreased, while the permeability performance gradually enhanced.

AbstractIn order to develop a synchronous grouting material with good comprehensive performance, this paper selected cement, fly ash, mineral powder and slag by orthogonal experimental design method to carry out the proportioning test research, which provided the most suitable slurry proportion for engineering construction. The effects of group proportioning on fluidity, compressive and flexural strength, impermeability and volumetric stability were investigated. The results show that the increase of mineral powder content improves the fluidity performance of the system; the slurry nodules with high cement dosage have higher mechanical properties and impermeability; the secondary hydration of fly ash plays a slower role, so it reduces the early strength of the material and increases the late strength; the slag reduces the impermeability and drying shrinkage of the nodules. The research focuses on the characteristics of synchronous grouting in a subway station construction project in Qingdao. It investigates the mechanical and engineering properties of a new type of material and applies it to the field of engineering control. To some extent, this material can replace cement and effectively prevent tunnel water leakage, reduce operation and maintenance costs, and extend the operation and maintenance cycle, showing significant potential for widespread application.

AbstractIn this paper, we present and discuss the initial results of a large-scale research project involving laboratory and field investigations of abrasion resistance of different types of concrete. The decision to study in more detail the abrasion resistance of fibre-reinforced concrete with granulated rubber was based on the results of previous research projects, as well as on observations on the behaviour of concretes placed in the spillways of hydro power plants loaded with water and water-borne particles. Gravel aggregate, steel, polypropylene fibres, and granulated rubber were used to prepare the concrete. In the fibre-reinforced concretes without granulated rubber, the binding component consisted of cement and silica fume, but when granulated rubber was added, the binding component consisted of cement and a dry proportion of SBR latex. The results obtained by now, at an age of 90 days show that fibre-reinforced concretes with granulated rubber have an improved resistance to underwater abrasion, compared to fibre-reinforced concretes without granulated rubber.

AbstractCement, aggregate, mineral admixture, concrete admixture, and mixing water were used as the main raw materials to prepare manufactured sand concrete. By adjusting the proportioning parameters of manufactured sand concrete, such as sand ratio and water-cement ratio, the influence of proportioning parameters on the durability of manufactured sand concrete was studied. Experimental results show that when the sand ratio is between 0.38 and 0.44, the mechanism of sand best workability and durability of the concrete strength, the best value for the mechanism of sand concrete, sand ratio range within the scope of the young stage of mechanism sand concrete stress is almost not affected by sand ratio increase, age stage mechanism of sand concrete stress along with the increase in sand ratio decreased significantly; The stress of natural medium sand concrete and manufactured sand concrete increases with the increase in the water-cement ratio, and the compressive strength of manufactured sand concrete is slightly higher than that of ordinary natural sand concrete. When the stone powder content is 10.5%, its filling performance is better, and the frost resistance of mechanized sand concrete can be improved by adjusting the stone powder content. When the powder volume is 158 dm3, the manufactured sand concrete has good workability and the highest durability. The increase in the water-binder ratio will lead to the aggravation of carbonization depth, serious carbonization phenomenon, and reduced durability of machined sand concrete.

AbstractThe study used electric arc furnace oxidizing slag (EAFOS) to substitute natural fine aggregates. However, EAFOS replacement may cause volumetric instability. Therefore, a cement, fly ash, or slag layer was coated with EAFOS as a precoated technique. Then, the effect of EAFOS on engineering properties was investigated, and the optimum amount of EAFOS was identified. The amount of coated binders was set at 20%, 25%, 30%, 35%, and 40% of the weight of EAFOS, and the water-to-binder ratio (w/b) of the coated binders was fixed at 0.50 to 0.20. The proportion of EAFOS replacing fine aggregates was 10%, 20%, 30%, 40%, and 50%, and the w/b of the mortar was fixed at 0.55. The results showed that the proportion of precoated binder was 30% of the EAFOS and the w/b was 0.30. Curing time was up to 28 days, and slag was the appropriate precoated binder. Maximum compressive strengths of mortars made with precoated EAFOS were 42.94 and 56.96 MPa at 7 and 28 days (40% replacement for fine aggregates). The maximum compressive strengths of specimens without coated EAFOS were 36.67 and 47.55 MPa at 7 and 28 days (the identical replacement). The drying shrinkage of 40% precoated slag specimens was 0.054% at 7 days and 0.074% at 28 days. The appearance of the specimens did not reveal any abnormality after 28 days of immersion in water at 70 °C. The precoated technique adopted in this study can be used as a stabilization procedure for replacing natural fine aggregates with EAFOS.

AbstractThis study aims to optimize the proportion of polymer composite repair mortar, with the objectives of enhancing its mechanical properties and reducing shrinkage, to ensure its application value in non-excavation repair construction of underground sewage pipelines. By taking the dosage of Hydroxypropyl Methyl Cellulose (HPMC), Cement-based Crystalline Capillary Waterproofing (CCCW), and Polypropylene Fiber (PPF) as key influencing factors, the Response Surface Methodology (RSM) was employed to design and optimize the proportions for 28-day compressive strength and 7-day shrinkage. The study not only analyzed the impact of the interaction of these factors on the material properties but also conducted microstructure analysis through SEM and XRD to reveal the reinforcement mechanism. The optimization results indicate that the optimal dosages of HPMC, CCCW, and PPF are 0.306%, 0.423%, respectively, achieving the predicted optimal performance, i.e., 28-day compressive strength of 73.6 MPa and 7-day shrinkage of 133.98 μm, with experimental verification errors of 2.3% and 4.5%, respectively. The achievements of this study provide important theoretical basis and practical guidance for developing high-performance, low-shrinkage repair materials, demonstrating the integration of traditional civil engineering practices with modern scientific methodologies, and contributing to the field of construction materials.

Abstract:
Abstract Cellulose, the one of the most abundant biomaterials available in nature, is a polymer with cellobiose as the smallest repeating unit, with a degree of polymerization that can go up to 1000 for wood cellulose. The strength-to-weight ratio of nanocellulose is eight times greater than steel (Patchiya Phanthong et al). Nanocellulose in suspension (NCS) at a varied concentration helps increase properties of cement without changing the density of the cement slurry. Being mindful of challenges in oil and gas wells, efforts were made to enhance cement properties using nanocellulose within co

Abstract:
Pervious concrete is considered an advanced pavement material in terms of environmental benefits resulting from its basic feature - high water permeability. While natural aggregate is a standard component for permeable concrete production, the paper presents the potential of air-cooled blast furnace slag aggregate. The aggregate is specific for its open internal structure and at the same time high hardness and strength, which was assumed to be advantageous for this type of concrete. As permeable concrete is characterized by a specific structure and low amount of binder, it needs for optimizati

Abstract:
Abstract. Light-weight structures are widely used in the construction field. Light-weight fillers such as aggregates can be used to improve weightless structures. Generally, standard aggregates cannot be used to attain the desired weight for light-weight structures. To determine a light-weight filler, the aggregates are made by using fly-ash along with cement mortar. Fly ash was collected from the Mettur Thermal power plant. Cement and fly-ash were mixed in a concrete mixer in a proportion of 30:70 with a water-cement ratio of 0.3 and it is mixed until the pellets are formed. The aggregates ar

Abstract:
Abstract Cementing is an important operation for the integrity of the wellbore due to its role in providing several functions. To perform these functions, a high performance cement is required. Different types of additives and materials have been added to the cement slurry to improve its performance. Tire waste material is considered one of the greatest wastes globally. It is a dangerous material to the environment and human. Subsequently, it has been included in many industrial processes to reduce its hazards. This work evaluated the application of tire waste material in oil and gas industry

Abstract:
Specialized classes of concrete, such as ultra-high-performance concrete, use volumes of silica fume in concrete that are higher than those in conventional concrete, resulting in increased water demand and mixing difficulty. This study considered the effects of eight different silica fumes in three dosages (10%, 20%, 30%) with three w/b (0.20, 0.30, 0.45) on rheological behavior as characterized by the Herschel-Bulkley model. Results indicated that the specific source of silica fume used, in addition to dosage and w/b, had a significant effect on the rheological behavior. As such, all silica f
