Multiparameter structure optimization of the cellular silicate concrete

Abstract

Strengthening the concept of energy efficiency requires the development and implementation of high-performance wall materials. The most promising in this respect is the cellular silicate concrete (gas silicate), which properties are superior to other insulating building materials. However, production of gas silicate insulation purpose with medium density less than 300 kg/m3 poses a number of difficulties due to the nature of its structure. In this regard, the current task is to maintain the specified quality of concrete porous silica with a decrease in its average density. In the article this problem is solved by a multi-level optimization of the macro- and microstructure based on multi-rich (multiparameter) mathematical model. Algorithm and the general structure of the model and the results of laboratory studies are given.
