摘要

PURPOSE: An environment-friendly cracking grout material, and a concrete crack repairing method using thereof are provided to improve the penetration force of the material by reducing the loss of inlet pressure. CONSTITUTION: An environment-friendly cracking grout material using an aluminosilicate system inorganic binder contains 10~50wt% of aluminosilicate system inorganic binder, 0.5~3wt% of CSA expansion agent, 0.5~3wt% of C12A7 accelerating agent, 0.2~0.4wt% of repair material, 20~38wt% of CaCO_3, 0.1~0.2wt% of super plasticizer, 10~55wt% of jade based mineral powder, and 5~40wt% of blast furnace slag cement.
