Studies of Heat Insulation Concrete

Abstract

The article analyzes the properties changes of non-autoclave foam on a protein foaming agent with the introduction of dispersed wollastonite and diopside. A decrease in the density of foam concrete (to the grade D300, D400), frost resistance of the material, as well as shrinkage deformations was noted. The optimal technological parameters have been determined, allowing to obtain more stable properties and structure of heat-insulating cement-ash non-autoclave foam concrete. The flow chart of the production of foam concrete of natural hardening in the separate preparation of foam and mortar is presented. The studies were performed at NSTU and NGASU (Novosibirsk) and the NII (Norilsk).

Numerical simulation of slurry basin impeller operation for mixing slurry mixtures in the production of cement compositions

“…One of the main conditions for the quality process of hydration of cement composites is a uniform volume distribution of highly dispersed filler [1][2][3][4][5][6][7][8][9].…”

Multi-Span Composite Timber Beams with Rational Steel Reinforcements

“…Composite materials are distinguished by the absence of wood defects and the greater resistance to warping, curliness, and other defects inherent in solid wood products [4]. The creation of new composite products follows market differentiation and filling specific market niches [5][6][7][8]. For example, in Russia, for many years, comprehensive studies of glued wooden reinforced structures have been carried out; new types of them have been developed and implemented in industry [9,10].…”
