Intelligent concrete crack self repairing material preparation method
The invention relates to an intelligent concrete crack self repairing material preparation method, which comprises the following steps: the raw materials of 30%-50% by mass of an active chemical component, 10%-20% of a reaction promoter, 10%-20% of an Al<3 +> additive, 10%-20% of a silicic acid radical additive, and 10%-20% of a Ca <2 + > additive are weighed; first, the active chemical component, the Ca <2 + > additive, the silicic acid radical additive and the Al<3 +> additive are weighed according to the weight ratio and evenly mixed; the mixture is placed in a ball mill for ball milling for 30min at the rotational speed controlled at 400r / min, the weight of screen residue of a 80um square hole sieve is less than 5%, finally the reaction promoter is added for mixing and milling for 15min to prepare concrete crack self repairing material masterbatch; when in use as a paint, a concrete crack self repairing material can be obtained by evenly mixing the masterbatch, quartz sand and cement according to the mass ratio of 1:10:20. The concrete crack self repairing material is simple and practical, and, compared with the prior art, can be used in the interior of concrete, also can be used by brushing on the surface of the concrete with cracks, and is convenient and easy to use. At the same time, the concrete crack self repairing material can also play a good effect to repair micro cracks, and the defects of large construction difficulty and not good enough repair effect of a bionic self repairing concrete construction method can be compensated.
