ROCKBOND FASTROCK GROUT (RB 3.05) powder contains a blend of fine cement powders, high quality graded sands, and a union of admixtures. The admixture also contains a unique system of chloride free accelerators. The powder is pre-mixed and ready-to-use and, when mixed with water, produces a fluid grout that develops an early gain in compressive strength. ROCKBOND FASTROCK CONCRETE (RB 3.06) powder contains a durable aggregate, and is applied to sections greater than 60mm. ROCKBOND FASTROCK ACCELERATED GROUT (RB 3.07) and ROCKBOND FASTROCK ACCELERATED CONCRETE (RB 3.08) are used when an early gain in strength is required when ambient temperatures are low. ROCKBOND FASTROCK GROUTS and CONCRETES are packaged in 25kg durable bags.
