Polypropylene(PP) Fiber Research and Applications in the Dry-Mixed Mortar

Mortar is the main construction raw material. With the development of economy, population growth, people’s higher requirements for environmental protection, so to realize the commoditization of mortar is an important mark when the construction industry has developed to a certain degree. The commoditization of mortar mainly use the concentration and fixed point mixing and bagged mixing mortar, namely dry powder mortar two forms.

It has the many advantages but also has some properties defect. For example, mortar product is easy to cause crack, enabling the natural water permeation and may reduce the construction durability, the low tenderness property of mortar products, low anti-tensile strength, low anti-shock, etc. For these problems, putting Polypropylene(PP) Fiber into dry-mixed mortar can prevent the mortar products crack effectively, increasing tenacity and anti-shock properties. This article researched on Polypropylene(PP) Fiber’s dispersion performance in the dry-mixed mortar, for adding fiber to dry-mixed mortar products ant--crack, anti-shock and other properties influence.
