High Strength Plaster from Fluorogypsum

Home » Technology » New Technologies » Building and Construction » High Strength Plaster from Fluorogypsum




Suitable for use in plastering – Finish coat & Base coat


Salient Features


The high strength plaster is developed by benefication and fine grinding of fluorogypsum and admixing it with suitable chemical activators. Plaster showed high compressive strength (30-35 MPa) and low water absorption (< 8 %) and porosity (<10 %) and complied with requirement as given in ASTM C-61-50. The technology for formulation of high strength plaster is simple and no heavy machinery is involved. The plaster is fire resistant, possess good acoustic properties, self strengthening with time and helps in conservation of cement.
