PRODUCT DESCRIPTION: BuMaFill is a preblended non-shrink, cementitious grout based on high strength cement, graded aggregates, silicafume with an expansive agent formulated by BUMATECH research laboratories. With a special blend of shrinkage - reducing and superplasticizer/ water-reducing agent, BuMaFill compensates for shrinkage in both the plastic and hardened states, and develops early flexural and compressive strength.
