Light weight concrete has many advantages that can be used in the construction of buildings. Perhaps one most important these features is its light weight, which contributes a lot to reducing stress on soil, provides possibility rising buildings and increasing number floors. In addition role thermal insulation impact consumption energy sources cooling heating, considered sustainability factors ...

This study assessed the usefulness of replacement coarse aggregate partially with electronic waste (e-waste) plastic in lightweight concrete since developing countries have been challenged management e-waste as well high cost aggregates for production. Coarse were replaced at 5%, 10%, 15%, and 20% a class C20. The particle size distribution was determined slump, compressive strength, water abso...

A new patented lightweight aggregates is tested. This type is given the name Flashag. The only solid raw material used to manufacture these aggregates is fly ash. The aggregates are sintered but not pelletized and the process is easy and inexpensive. This paper describes these patented aggregates and compares them with other lightweight and normal-weight aggregates that are used for concrete. T...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...
