Evaluation of the efficiency of using solar energy in the production of building composites

Abstract

The results of research of speed of set of durability of fine-grained concrete are in-process presented on a compression which hardened in solar chamber of cyclic action. The analysis of existent types of industrial solar chambers is conducted and basic structural elements are considered. Resulted calculation of thermal balance of solar chambers. Experiments are conducted on compositions of fine-grained concrete on cement astringent with the use of additions of superplasticizers of firm MC - Bauchemie: MC - PowerFlow 3100 and MC - PowerFlow 2695. After self-control in solar chamber of cyclic action durability was determined determined at the different terms of hardening. The comparative analysis of results of durability is conducted on the compression of concrete in solar chamber and chamber of the normal hardening.
