It was investigated the influence of mechanical activation process of natural pearlite on its pozzolanic activity and the comprehensive assessment was carried out of ultrafine pearlite as the basis of organomineral additive and part of a multi-component fine cement and low water requirement binder. Concretes with low water requirement binder and pearlite were obtained and investigated.
