ACT FIBERS are 1/2” strands of virgin homo-polymer, polypropylene multifilament fibers specifically engineered to help reinforce against plastic shrinkage crack formation in cement based and gypsum based mixes.

Category: Brand:


add tensile strain capacity to freshly placed cement based and gypsum based mixes reducing plastic shrinkage cracking in excess of 85%.

ACT FIBERS also increase abrasion, shatter and impact resistance, reduced permeability and higher compressive and flexural strengths.

Inhibits and controls the formation of cracking • Reinforces against impact forces, abrasion and water migration • Reduces plastic shrinkage and settlement cracking • Does not affect finish troweling • Replaces welded wire fabric when used for secondary (crack control) reinforcing in concrete. • Rustproof • Alkaline resistant
