Fly ash is a waste produced mostly from the burning of coal in thermal power stations, which contributes to environmental pollution. Also, a number of studies have been conducted to investigate the influence of randomly oriented fibers on the engineering behavior of coarse grained and fine grained soils. The influence of randomly oriented polypropylene fibers on the engineering behavior of soil...

This study reports the influence of different climatic ambient temperatures on thermal properties fiber-reinforced lightweight aggregate concrete (LWAC). Lightweight expanded clay aggregates (LECA) with steel (ST) and polypropylene fibers were used in mix proportions. The steady-state test was performed samples at oven-dry state measurement taken six 0 °C, 10 20 30 40 50 °C. results show a line...

Abstract Fire is considered one of the main risks leading to building collapse. Lightweight concrete comprises a variety components, each which has distinct behavior under effect temperature change. A total 16 mixtures were investigated in this article. reference mix comprising simply ordinary Portland cement and ten mixes having varying percentages fine coarse lightweight aggregates (pumice), ...

This paper is concerned with the modeling and analysis of the orientation and distance between steel fibers in X-ray micro-tomography data. The advantage of combining both orientation and separation in a model is that it helps provide a detailed understanding of how the steel fibers are arranged, which is easy to compare. The developed models are designed to summarize the randomness of the orie...

Sometimes civil engineering infrastructures have been constructed in hot and cold weathering regions such as desert areas. In situations, the concrete is not only smashed by processes but also spoiled shrinkage cracking. Therefore, this study intends to examine influence of heat–cool cycles on high-strength comprising various fibers, natural date palm, polypropylene, steel their different volum...

In recent times, the applications of fiber-reinforced recycled aggregate concrete (FRAC) in practical engineering have gained greater popularity due to its superior mechanical strength and fracture properties. To apply FRAC buildings other infrastructures, a thorough understanding residual properties durability after exposure fire is highly important. According established research, volume frac...
