Preparation of Calcium Silicate Board by Fly-Ash Based Calcium Silicate Powder by Press Molding

Abstract:

Calcium silicate board has been prepared by press molding from fly-ash based calcium silicate powder with the pulp fiber as the reinforcing fibre. The micro-morphology and crystal structure of the obtained calcium silicate board were analyzed by SEM and XRD. The effects of cement,silica fume and molding pressure on the flexural strength and thermal conductivity of calcium silicate board were investigated. When the molding pressure is 10MPa, samples flexural strength, bulk density and thermal conductivity are 5MPa, 0.7g/cm³ and 0.12 W/m·K respectively. It was found that this kind of calcium silicate powder was complete hydrated and could not be further hydrated even in autoclave curing.
