  • Review on the Durability of Polypropylene Fibre

    Polypropylene fibre (PPF) is a kind of polymer material with light weight, high strength, and corrosion resistance. The crack resistance of concrete can be improved by adding PPFs. PPF can optimize the pore size distribution of concrete. As a result, the durability of concrete is significantly enhanced since PPF can block the penetration of High Performance Concrete Additives Construction ,According to Fabienne Drouel of French company Coatex Group, one of the world’s leading designer and producer of waterbased rheology additives; because of the high demand for quality concrete and the high performance additives the contractors are looking for today, it is important to break the limits of performance with newly developedTypes of Admixtures & Additives for Concrete DIY Doctor,There are essentially 5 distinct types of admixtures or functions as they are known in the trades; waterreducing, plasticizers or superplasticizers, airentraining, retarding and accelerating.
