| Abstract: | Based on the analysis of the application and manufacture mechanism of additives, a kind of additive of anti-inhibition and resistance-permeability is produced by means of orthogonal experimental design method, and the influence regularity of every ingredient is discussed. The result of comparative experiment proved that this additive possesses excellent workability of micro-expansion, strength promotion, low hydration heat and low desiccation deformation. It can improve the anti-cracking performance of concrete when used as auxiliary selfwaterproof cementitious materials of concrete structures. |
