Abstract
This paper presents an analysis of the mineral additives of volcanic origin usage experience for the preparation of a composite binder. In theory, it is proved that an active pozzolan, which are the chemical basis of fine raw materials of volcanic origin, allow using them as additives for cements to solve the problems of reduction in the cement stone of free calcium hydroxide content, to make full use of the potential of cement capabilities by increasing its hydration and getting stronger and stable structure of low-based calcium hydrosilicates with high sulphate. It was determined that the most important characteristics of the porous aggregates is their bulk density and compressive strength. From the porous aggregates used for the lightweight concrete the most economical are natural in case they do not need to be transported (local materials). However, artificial binders are of much more effective use in lightweight concrete aggregates. Volumetric bulk density of crushed stone and sand derived from vermiculite, depends on the quality of the breed technologies and swelling and is of 60-400 kg / m3. The authors argue that the expanded vermiculite is usually used for the same purposes as the expanded perlite. Selection of the composition of lightweight concrete with porous aggregates. Selection of the composition of lightweight concrete with porous aggregates lies in experimental finding the amount of the raw materials that provide the necessary concrete workability, strength and weight of a given volume of the hardened concrete. The authors reveal that the deposit (structural and geological analysis is held) have great prospects to develop, and can be identified as leading in the calculation of the economic strategy of the material production.
Keywords: Mineral supplements; volcanic ash; composite binders; calcium hydrosilicates; structure; dynamics.
