Anti-cracking leakage-proof cement

Abstract

The invention relates to an anti-cracking and anti-leaking cement which considers the portland cement as the raw materials. Meanwhile, it mixes 2.5%-41% by weight of Fe powder into the portland cement and blends uniformly. The added Fe powder with a certain proportion reacts with the air and water to make Fe expand swiftly. The produced powerful penetrability drives cement to automatically fill up the capillary porosity and crack to make the cement imperviousness and conquer the chap and aging of the beton and prolong its service life.

Description

technical field [0001] The invention relates to cement materials for construction, in particular to a kind of cement with anti-crack and anti-leakage. Background technique [0002] In building construction, cement is often used to lay the ground plane on the prefabricated blocks of reinforced concrete structure, especially for the plane of the roof or bridge deck. Seriously, for this kind of phenomenon, the commonly used methods are sealing, covering, plugging, etc., that is, methods such as painting waterproof glue or laying waterproof linoleum on the outside to repair leakage and impermeability, but these methods are difficult to achieve a radical cure. Moreover, the laying of waterproof linoleum needs heating, and the workload is relatively large. Applying waterproof glue only forms a waterproof film on the surface, which has poor durability, and it is not suitable for large-scale use, that is, this method is expensive, laborious and time-consuming. .
