Wollastonite’s unique chemical and structural composition has made it a performance reinforcement for the construction industry. The only naturally occurring, white, non-metallic mineral that is acicular (needle-like) in shape, wollastonite enhances strength and increases durability in a range of construction materials including concrete, stucco, EIFS systems, patching compounds and adhesives. It also provides added dimensional stability, sag resistance and resistance to cracking from drying and freeze thaw effects. |

The key benefits of wollastonite in the construction materials Wollastonite’s chemistry is a key advantage in applications requiring a calcium and silica source for reactivity to improve bonding and, because of its very low carbonate content, in efforts to reduce CO2 emissions. • Higher Compressive and Flexural Strength • Improved Dimensional Stability • Lower Coefficient of Linear Thermal Expansion • Micro Reinforcing for Reduced Cracking • Increased Weatherability • Improved Mar/Scratch Resistance • Key Ingredient in the Replacement of Asbestos and Other Fibers | ||||
Wollastonite as a functional filler was widely used in the construction materials It can significantly improve the impact resistance, bending strength, bearing capacity, wear resistance, anti-corrosion, heat insulation and fire resistance of new environmental protection building materials such as calcium silicate board, fire-proof board, fiber cement board, calcium sulfate plate, building formwork, etc. It can also be used in ceramics, white cement, etc. |
