Glassfiber Reinforced Concrete
GRC is a combination of specially prepared Alkaline Resistant Glassfibres and cement with sand mortar. The mixed composite material having compressive properties of cement mortars with the valuable flexural and tensile strength of the glass fibres. It is similar to concrete but its higher cement content and lower permeability make it more resistant to moisture penetration, atmospheric attack or sand erosion and also reducing the weightage. The high cement and low aggregate content also result in higher moisture movement than concrete, although thermal movement is similar. This is environment-friendly composite using natural raw material is transformed into a great variety of products. Due to its flexibility to meet performance, appearance and cost parameters, GRC products are popular among designers, architects, engineers and end users.
