Abstract:

In this study, cement mortars with different strengths are poured into the large void matrix asphalt macadam material as a semiflexible pavement (SFP) material and the experimental research is carried out. The current research on SFP is mainly focused on the performance of grouting materials and the influence of grouting matrix materials on the overall mechanical properties of SFP and road performance. However, there are some flaws in the study of the influence of grouting material strength on the performance of SFP materials: the difference between the strengths of the selected grouting mater

The application of grouting technology in the reinforcement and water shutoff of underground engineering is very extensive. The grouting technology mainly includes two aspects: grouting process and grouting material. The grouting material is a vital link in grouting. It affects the cost of construction directly, and determines the success or failure of the engineering. The smaller the molecular dimension of solution or solid particle dimension, the greater the scope that the grout can be injected into. And it is beneficial to the grouting effect.

By changing sleeve-rib space, the influence of sleeve-rib space on the stress and the displacement distribution at grouting material were gotten. Numerical simulation shows that with the decrease of sleeve-rib space, the internal force distribution of grouting material tends to be uniform. Under axial tension load, with the sleeve-rib space of 14mm, the maximum stress of grouting material is lower than its strength, which makes grouting-sl

Abstract:

Grouting technology is to inject slurry with cementing ability into the cracks and voids of the formation to achieve the purpose of reinforcement and filling. At present, cement-based materials are mainly used for grouting, which has the advantages of mature technology, cheap price, high stone strength and wide application, but there are also defects such as high-water separation rate, poor stability and long setting time. Most importantly, the production of cement materials consumes a lot of energy and emits a lot of CO2, which aggravates the global greenhouse effect and is not in line with t

Abstract:

In deep coal mining, grouting reinforcement and water blockage are the most effective means for reinforcing the rock mass of extremely broken coal. However, traditional cement grouting materials are not suitable for use in complex strata because of their insufficient early mechanical strength and slow setting time. This study innovatively proposes using alkali-activated grouting material to compensate for the shortcomings of traditional grouting materials and strengthen the reinforcement of extremely unstable broken coal and rock mass. The alkali-activated grouting material was prepared using

The construction of tunnels involves massive excavation work and generates an enormous amount of waste slag. The improper disposal of the waste slag may cause environmental pollution. The treatment of waste slag is usually costly. In this study, the feasibility of recycling waste slag as a component in the synchronous grouting material was investigated. A series of experimental measurements were conducted to evaluate the performance of grouting material with different proportions of recycled waste slag. The experimental results show that the grouting material with the selected proportion of re

Grouting materials require not only high ultra-early-stage strength of the stone body, but also proper working performances, such as high fluidity and fast setting time, as well as good stability. Compared with the traditional pure cement grout, geopolymer grouting material has the advantages of fast setting time, high fluidity, good slurry stability, and high early strength of the slurry stone body, which is beneficial to reuse solid waste resources and can be applied to the conditions of rapid construction or repair work to a certain extent.

Epoxy resins are widely used for repairing cracks in stone, mortar and masonry. A main factor that influences the grouting quality is the permeability of grout. However, the permeability will deteriorate over time because of the reaction of chemical grouting materials, which will greatly affect the results of grouting. To the best of our knowledge, there are few reports that focus on the time-varying properties of viscosity and affinity of epoxy resins grouting material. In this paper, we investigate the changing rules of viscosity and affinity with time by studying the viscosity, surface tens
