Kinetics of mixed binder strength gain

Introduction . The storage of pond ash at dumps has a negative impact on the environmental situation in nearby settlements, constantly dust and pollute water sources. To solve this problem, it is proposed to use from as component mixed binder. Since specific surface area different throughout dump, necessary study its influence strength set binder under curing conditions. Materials methods equipment which experiment was carried out listed. determine ПСХ-12 device used, drying desiccator. samples were stored normal solidification chamber. chemical composition TPP-5 Omsk presented. Results Experimental data age 1,3,7,14,21,28,90 days hardening after heat humidity treatment are Durability with hydraulic 460-490 m2/kg conditions amounts 42.57 MPa corresponds natural strength. removal increased by 12% comparison control composition. Compositions wet 220-250, 340-370, 650-700 show durability results lower than ashless irrespective Discussion conclusions It proved that rational. Its 42,57 MPa, concrete. moisture an increase compared Increased compositions associated acceleration pozzolanic reaction them, products have positive effect products.
