PURPOSE:To improve the durability, workability and strength of concrete by using prescribed amts. of 3CaO.3Al2O3.CaF2, inorg. sulfate, cement, alkali carbonate and oxycarboxylic acids as essential components and regulating the slump value to 0cm. CONSTITUTION:This rapid-hardening ultrastiff-consistency concrete contains 3CaO.3Al2O3.CaF2, inorg. sulfate, cement, alkali carbonate and oxycarboxylic acids as essential components and is characterized by 0cm slump value. The amt. of the inorg. sulfate contained is 50-250 pts.wt. per 100 pts.wt. 3CaO.3Al2 O3.CaF2. |
