Abstract

Изобретение относится к технологии приготовления вяжущих композиционных материалов низкой водопотребности (ВНВ) на основе портландцементного клинкера и может быть использовано при производстве самоуплотняющихся, высокопрочных и высококачественных бетонов для строительных конструкций. Технический результат изобретения характеризуется применением механоактивированных тонко молотых ультрадисперсных компонентов гранитоидных пород путем гравитационно-аэродинамической каскадной сепарации гранитоидной сырьевой смеси. Вяжущее низкой водопотребности (ВНВ) включает портландцементный клинкер, минеральную добавку и водопонижающий компонент. Согласно изобретению в ВНВ введены тонко молотые компоненты ультрадисперсных гранитоидных пород фракций от 0,0001 до 160 мкм химического состава, мас.%: SiO2 - 50-65; Al2O3 - 7-17,2; Na2O - 2,2-6,4; MgO - 2,75-2,8; K2O - 3,4-4,6; CaO - 4,0-7,3; TiO2 - 0,7-1,8; Fe2O3 - 5,1-16,1; SO3 - 0,1-0,35; Cl - 0,04-0,3; BaO - 0,1-0,5; P2O5 - 0,2-0,9; ппп - 0,5-1,9, с пуццолановой активностью до 80 мг/г, при следующем содержании компонентов, мас.%: портландцементный клинкер СЕМ - 45-90; тонко молотые гранитоидные породы - 10-35; порошкообразный поликарбоксилатный пластификатор - 0,5-2,0.The invention relates to a technology for the preparation of binding composite materials of low water demand (VNV) based on Portland cement clinker and can be used in the production of self-compacting, high-strength and high-quality concretes for building structures. The technical result of the invention is characterized by the use of mechanically activated finely ground ultradispersed components of granitoid rocks by means of gravitational-aerodynamic cascade separation of the granitoid raw mixture. Low water demand binder (LWD) includes Portland cement clinker, mineral additive and dewatering component. According to the invention, finely ground components of ultradispersed granitoid rocks of fractions from 0.0001 to 160 microns of chemical composition, wt% are introduced into VNV: SiO2 - 50-65; Al2O3 7-17.2; Na2O 2.2-6.4; MgO 2.75-2.8; K2O 3.4-4.6; CaO 4.0-7.3; TiO2 - 0.7-1.8; Fe2O3 5.1-16.1; SO3 - 0.1-0.35; Cl - 0.04-0.3; BaO - 0.1-0.5; P2O5 0.2-0.9; PPP - 0.5-1.9, with pozzolanic activity up to 80 mg / g, with the following content of components, wt%: Portland cement clinker CEM - 45-90; finely ground granitoid rocks - 10-35; powdered polycarboxylate plasticizer - 0.5-2.0.
