Influence of Temperature on Structure Formation Processes Geocements for Rehabilitation of Concrete

Abstract:

When using geocements composition (xNa₂O+yK₂O)·Al₂O₃·(2÷4)SiO₂·10H₂O for protective coating of concrete from aggressive environments, the main problem is to determine the optimal treatment temperature, which depends on the ratio of basic oxides structural formula. In this work, using two-factor three level method of experiment planning determined that when the content as a part geocement (0,8÷0,9Na₂O+0,2÷0,1K₂O) and the ratio of SiO₂/Al₂O₃=2,5÷3,5 achieved the necessary water resistance - C_r>0,8 at 40°C. When the ratio of SiO₂/Al₂O₃>3,5 physico-mechanical properties geocement growing and processing temperature also increases to 50÷60°C. In subsequent researches will explore the possibility of reducing the processing temperature by modifying the geocement in the direction of accelerating processes of structure formation.
