Determination and investigation of longitudinal deformations of shortening of steel-reinforced concrete structures is an important step in the calculation of complex spatial schemes of buildings. Ignoring these deformations can make it difficult to operate the facility and, in some cases, lead to the failure of adjacent structures. The study of longitudinal deformations of shortening of steel-reinforced concrete structures has not been given due attention before. The longitudinal deformations of shortening for steel-reinforced concrete compressed elements using a large range of heavy concretes

Thermal stress is a major cause of early-age crack of massive concrete structures. In order to analyze the influencing factors of concrete crack under thermal loads, a series of tests were conducted using the improved Temperature Stress Testing Machine (TSTM). Effects of temperature on crack resistance of concrete were studied on different concrete placing temperatures and curing temperatures. Meanwhile, the roles of reinforcement on concrete crack resistance and crack-width limitation were quantitative analyzed, which compare cracks of plain concrete and reinforced concrete with the same mix

Reinforced concrete (RC) structures have the ability to be extremely durable and able to withstand a diversity of different environmental cases. However, failure in these structures still happens due to precocious reinforcement erosion. If steel reinforcement corrodes in concrete structures, this leads to a decrease in the lifetime and durability of these structures, which cause early failure of the structures, costing significantly to inspect and maintain the deteriorating structures. Then, monitoring of reinforcement corrosion is of great importance to prevent early failure of structures. St

In civil engineering, many structures are made of reinforced concrete. Most degradation processes relevant to this material, e.g., corrosion, are related to an increased level of material moisture. Therefore, moisture monitoring in reinforced concrete is regarded as a crucial method for structural health monitoring. In this study, passive radio frequency identification (RFID)-based sensors are embedded into the concrete. They are well suited for long-term operation over decades and are well protected against harsh environmental conditions. The energy supply and the data transfer of the humidit

Abstract Practical application of expansive concretes in reinforced concrete structures needs the rational design model for assessment the early-age stress-strain parameters of self-stressing concrete elements under any restraint conditions during the expansion stage. Various strategies are used to calculate the restrained expansion strains and self-stresses but, in most cases, disregarding the elastic-plastic behaviour of expansive concrete at early ages. It’s noticeable that in case of bi-axial restraint conditions both the elastic-plastic parameters of expansive concrete and the influence o

The creation of self-compacting concrete (SCC) is associated with the introduction of plasticizing additives based on polycarboxylate esters (PCE). The first patent for a group of substances proposed for use as superplasticizers for concrete, was declared in the early 80-ies of the last century in Japan. In the mid 90-ies superplasticizers based on esters of polycarboxylates began to be used in Europe. In Russia, the use of self-compacting concrete began much later, and in bridge and tunnel construction almost a few years ago. Currently, in the European Union, 70-80% of reinforced concrete str

Generally, adding of steel fibres in concrete improves the significance of the concrete mix and it also reduces the workability of the concrete. Steel fibre reinforced concrete SFRC is a Composite material which is made up of hydraulic cements. It contains coarse and fine aggregate. Since, cement having well compressive and steel having tensile strength it is capable of resisting wind and earthquake forces. Although reinforcing brittle materials with fibres is not a new concept, it was started in the early 1960s. Steel fibres added to concrete, steel fibre reinforced concrete SFRC is formed wh

To address the cracking and leaking of concrete in frozen shaft linings in deep and thick topsoil layers in coal mines, hybrid-fiber-reinforced concrete (HFRC) was developed. First, the composition of the reference concrete was obtained by investigating high-strength concrete commonly used in shaft linings, and two dosages of polyvinyl alcohol fiber (PVAF) and polypropylene plastic steel fiber (PPSF) were obtained by the mixing test. Then, tests of early cracks of concrete were conducted; results showed that HFRC could almost avoid early cracks, exhibiting an advantage in early crack resistanc

During construction of the massive monolithic reinforced concrete structures, concrete hardening takes place in the unsteady abnormal temperature conditions, which, along with the massiveness of the structure and concrete recipe features, influence significantly on the concrete strength gaining kinetics. The non-homogeneity of the temperature field leads to the difference of the hardening concrete strength and deformation indicators in the different points of a structure at one and the same time, eventually resulting in formation of the non-homogeneous stress field.
