Abstract: An experimental and statistical study on the impact resistance of ultrahigh-performance concrete (UHPC) is presented. The impact resistance was evaluated by conducting the drop-weight impact test with a hammer of 10 kg ...

Abstract: Ultra-high performance concrete (UHPC) has more severe autogenous shrinkage than ordinary concrete, which may lead to increased cracking risks. Thus, a suitable and effective agent for internal curing (IC) of UHPC without ...

Abstract: Early-age cracking of concrete may influence the long-term durability of a structure. Cracking occurs when the tensile stress in concrete exceeds its tensile strength. Early-age stress development in concrete is influenced ...

Abstract: Fillers have been commonly used to replace a portion of cement in ultra-high-performance concrete (UHPC) for economic and eco-friendly purposes. However, mostly only the type and amount of filler are addressed, and limited ...

Abstract: Mortar, as concrete-like coarse-structured materials, has a fracture process zone ahead of crack tip after the crack initiation. The maximum fracture load must be related to the cohesive crack-tip local fracture energy due ...

Abstract: Coal seam water injection is widely used to reduce dust pollution and mitigate rock burst disasters. Evaluating its effectiveness depends on understanding the water content and distribution within the coal seams. Therefore, ...
