摘要:
The article investigated the influence of Super Absorbent Polymers (SAPs) with absorption behaviors on the consistency, fluidity, water absorption, mechanical properties, early crack resistance, permeability resistance, and degree of hydration of cementitious construction materials. Mechanical strength was investigated using a flexural and compressive strength test machine. Nonevaporable water content was employed to assess the degree of hydration of the cement powders. The durability of mortar was characterized using early crack resistance and a permeability resistance test. Furthermore, the ...
