TECHNOGENIC SANDS AS EFFECTIVE FILLER for FINE-GRAINED FIBRE CONCRETE

Abstract

In the article the use of technogenic raw materials (dropout of quartzite sandstone crushing) as filler for concrete is considered. Methods of research of the filler by the leading scientists of Russia are given. The physical and mechanical characteristics of the filler such as: size modulus, bulk density, real density, voidness, water demand, cement demand, are considered. Studies prove the possibility of effective use of droupout of quartzite sandstone crushing as filler for fibre concrete.
