Statistics of recent years shows an annual increase in the volume technogenic waste (in particular "tailings") mining and metallurgical enterprises Kazakhstan by about 1.5 billion tons, which at current time is already 4.7 that entails certain environmental economic consequences. This article proposes potential use tailings as a fine aggregate to partially replace consumption cement concrete mi...

Recycled aggregates present a varied mineralogical composition and the grading of these particulates over their particle size distribution influence aggregate properties as well those composites that they form. This study proposed comparative investigation fine from two different origins, namely, natural crushed stone construction demolition waste (CDW). Three distributions were defined, so eac...

One-third of the total waste generated in world is construction and demolition waste. Reducing life cycle building materials includes increasing their recycling reuse by using recycled aggregates. By preventing, need to open new aggregate quarries reducing amount dumped into landfills, use concrete drum compacted protects environment. Four samples PRCC were prepared for testing (compressive str...

Abstract This study examines the use of sillimanite as a fine aggregate in production temperature-resistant reactive powder concrete. The impact high temperatures on mechanical strength concrete with High Alumina cement is investigated. effectiveness utilizing glass and properties RPC at investigated this research. samples were heated muffle furnace to desired then tested for their residual com...

This research aims to create green concrete with acceptable characteristics by recycling glass and plastic waste together. Cement was partially replaced a 15% powder weight mixture fine aggregates 5% crushed mixture. According the findings, adding alone enhanced its qualities, such as compressive strength, splitting tensile flexural energy capacity, bond compared reference sample. The strength ...
