Recycled Technogenic Raw Materials as an Effective Filler for Modern Construction Composites

Abstract

Technogenic wastes, which utilization is an urgent issue in developed countries, is quite interesting for the production of fine-ground filler used to produce modern high quality concrete. The amount of technogenic waste (or technogenic raw materials, secondary raw materials) is so big that some sources refer to it as to the technogenic raw materials base for the production of composite concrete. Keywords-concrete mix, superplasticizer, technogenic raw materials, concrete scrap, crushed brick, ash and slag waste, quartz sand, filler, efficiency, water gain of concrete mixI.

Structure Formation Features of Non-Autoclaved Gas Concrete Matrix on the Basis of Composite Binders with Various Mineral Additives

“…As it was established in a number of works [11,12] additives CC and CCW have among those examined the highest grindability and activity on Ca (OH)2 absorption (refer with table 2) that explains their good strength properties. With further hardening (10 ... 28 days), the majority of the considered compositions uniformly gain strength with a significantly lower speed.…”
