Abstract

The further development of civilization is decelerated by lack of energy resources. This is especially significant for the construction industry. Considerable energy savings can be achieved by using specially prepared raw materials. Examples of these raw materials are volcanic rocks of the Republic of Buryatia. The modern complex approach to solving problems also requires additional development of resource-saving technologies, which imply the widespread use of associated industrial products, designed to significantly reduce the energy intensity of cement and concrete production without a fundamental change in technology. The paper deals with the use of natural pearlite and fly ash of Gusinoozersk thermal power plant (TPP) to obtain composite binders. It was investigated that natural pearlite and fly ash can be used as part of a multi-component fine cement and low water requirement binder (LWB). Compositions of binders were obtained with super plasticizers based on sulphonated naphthalene-formaldehyde polycondensates - C-3 and based on polycarboxylates - Sika Viscocrete. It is shown that the mechanism of action of these additives on the properties of the composite binders appears in the range up to 15 nm.
