An abrasive polymer fiber is used instead of steel fibers to reinforce cement mortars. Compared to steel fibers, it is easier to distribute and mix in cement mixers, without causing damage to the mixing and feeding concrete equipment. PRIMARY polypropylene is used as raw material for the production of rigid polymer fiber. This type of fiber has increased strength from ruptures. Given these features, a rigid polymer fiber can be widely used instead of steel fibers to reinforce cement mortars, giving the resulting concrete an increased resistance to cracking. Features: This fiber is an alternative of using of steel fiber. Designed for heavy concrete and screed. Operated in harsh conditions. Technical specifications:
Range of application
Reinforcement of heavy concrete, increase of strength characteristics of industrial screeds, reinforcement of structural characteristics of foundations, bridge floors, etc.
Effect of application
The use of a rigid polymer fiber can significantly reduce costs in comparison with the use of steel fiber (the specific mass of the steel fiber is about 9 times larger, respectively, the number of individual fibers is less). Polymer fiber does not adversely affect mixers and distributors of concrete, and is also not susceptible to corrosion.
Instructions for use
Dosage: The volume fraction of reinforcing fiber in heavy concretes should be at least 0.3%, which corresponds to 2.7 kg of rigid polymer fiber. Depending on the type of concrete and operating conditions, the recommended amount of rigid polypropylene fiber varies within the following limits:
