Non-Autoclaved Aerated Concrete on the Basis of Composite Binder Using Technogenic Raw Materials

Abstract

Non-autoclaved aerated concrete certain advantages are significantly lower production organization costs and technology energy intensity due to the lack of autoclave curing, the possibility of different scales industries foundation as well as monolithic construction applications. All of this allows to solve complex problems of various purposes buildings erection, heat and noise insulation. Portland cement consumption significant reduction and material properties management can be achieved through use of composite binders containing local natural and technogenic components selected on the basis of their genesis and properties. The applicability of heavy concrete and ceramic bricks processing wastes as well as such large-tonnage extraction of iron ore as sandstones granulation selection as mineral additive for non-autoclaved aerated concrete production as well as a number of accompanying issues of the of a high-quality pore space structures formation control are considered in the present article.

Acoustic Properties of Innovative Concretes: A Review

“…Since a material’s acoustic properties depend mostly on its density, lightweight concrete such as CRC containing a higher proportion of crumb rubber could absorb more sound. Hence, the ability to reflect more sound energy increases [ 32 , 94 ]. Due to this, CRC panels have been used mostly in office buildings as exterior cladding or on balconies of buildings.…”

Development of nanomodified rapid hardening clinker-efficient concretes based on composite Portland cements

“…It should be noted that with an increase volume of fine mineral additives, porosity of the matrix in concrete decreases. However, when maximum of filling the packing with a mineral additive is reached, concrete strength is reduced because of decrease in adhesion of cement stone with filler [14]. On the other hand, granulometric composition of fillers has a significant influence on technological properties of concrete mix and durability of concrete.…”

Analysis of the Quality of Quartz-Feldspar Sand as a Component of a Composite Binder

“…An important role is played by the chemical interaction of the components of the binder when mixed with water. At the same time, the formed macro-and microstructure has a direct impact on performance characteristics [1][2][3][4][5]. The production of composite binders is based on joint grinding of the silica component and cement.…”
