A STUDY ON THE NEW WATER LEAK REPAIR METHOD FOR

study contained CSA expansive agent, geo-material and carbonate group-based chemical additive. The CSA agent which gives expansion by forming ettringite (3CaO Al2O3 3CaSO4 32H2O) through hydration is commonly used for shrinkage compensation or chemical prestressing. Geo-materials generally include sand, clay, rock and other natural sediments.

Investigation on expansion effect of the expansive agents

The compensation of shrinkage by adding EA is one of the effective methods, which was widely used for the crack prevention . The mostly common method for reducing shrinkage and producing expansive concrete is to form expansive ettringite , other EAs such as free lime-based EA and MgO-type EA are also used [, , ].
