Polymer Cement Concrete (PCC) is a type of concrete that incorporates polymers to improve its properties. This composite material is designed to enhance the performance of traditional concrete by increasing its strength, durability, and resistance to various environmental factors.
History
The concept of polymer-modified concrete was introduced in the 1990s and has since become a common material in the construction industry[1][2].
Composition
Polymer Cement Concrete is created by substituting all or part of the cement hydrate binder with polymers. Various types and forms of polymers are used as chemical admixtures, including latexes, liquid resins, redispersible powders, and water-soluble homo- or copolymers[1]. The selection of polymer type and form depends on the intended use of the concrete and the desired properties, such as strength, chemical resistance, and durability[1].
Mechanism
The incorporation of polymers into the cementitious matrix changes the microstructure of concrete. The polymer particles are dispersed in water, and as the water evaporates, the particles agglomerate and form a dense array. This process results in the coalescence of polymer particles into a homogeneous film, which enhances the cohesion and adhesion properties of the concrete[1].
Properties
Polymer Cement Concrete exhibits improved mechanical properties, including increased strength, better workability, and enhanced durability. It also shows reduced water absorption and decreased total porosity, making it suitable for various applications such as repair mortars, waterproofing membranes, self-leveling compounds, and tile adhesives[1].
Applications
Due to its superior properties, Polymer Cement Concrete is used in a variety of applications, including:
- Repair mortars
- Waterproofing membranes
- Self-leveling compounds
- Tile adhesives[1]
