Abstract (en)
[origin: WO9304007A1] The present invention relates to a water-resistant building material which comprises: 0.2 to 6 % by weight of water-proofing additive; 0.5 to 10 % by weight of fly ash; 0 to 5 % by weight of Portland cement; and the balance being gypsum and optionally at least one other additive, all of the above percentages by weight being based on the weight of the total composition. The present invention also provides a method for producing the water-resistant building material and a water-resistant plasterboard construction containing the water-resistant building material.
