Specco A-80 is a non-chloride, accelerating admixture designed to aid the placement of mortars and grouts in cold or sub-freezing temperatures. A-80 allows improved mortar workability, increases early and final strength gain formation, and can be used over a wide range of temperatures by varying the dosage. A-80 is formulated to comply with ASTM C-494 Type C and E guideline. A-80 can also be used to accelerate ready mix, mobile mix, precast block, and precast concrete.
