Causes of Concrete Crack Leakage and Treatment Measures

phenomenon
Concrete surface irregular shrinkage cracks or annular cracks, cracks penetrate when the body of the concrete structure, that is, leakage.
Cause Analysis The cause of concrete crack leakage is the same as that of "concrete structure crack quality problem".
Control measures
(1) to strengthen the conservation of concrete, reducing the temperature difference between inside and outside the concrete, make temperature records, and strictly control the quality of commercial concrete, optimize the mix of concrete, in strict accordance with the norms required for construction.
(2) with alkali-resistant polymer latex and other materials sealed with alkaline substances in cement chemical changes, the formation of high stability of the silicate, the carbonation of the carbonation of fracture surface fragile.
(3) deep or penetrating cracks, with epoxy grouting, in the surface plus brush epoxy clay closed. Cyanide condensate can also be used, C pour liquid pouring joints, and then the surface closed.
