Abstract:
Describes the use of `Balcrete' for the production of light weight cellular plaster boards. It is possible to make these boards having a density ranging from 20 to 60 lbs.. per cu. ft. using 0.1-0.2% of `Balcrete' by weight of plaster and with water: plaster ratio of 0.5:0.7. The flexural strength of these boards is about the same as cellular concrete or clay bricks, but the compressive strength is comparatively less. The thermal conductivity rises sharply in the density range of 20-40 lbs. per cu. ft .and gradually thereafter. Treatment of these boards with sodium silicate makes them water resistant.
