Abstract

1,274,665. Concretes. NATIONAL RESEARCH DEVELOPMENT CORP. 28 May, 1969 [28 May, 1968], No. 25476/68. Heading C1H. A concrete mix used for preparing articles by pressing in a mould contains asbestos cement dust as replacement for part of the fine components. The weight of asbestos cement dust does not exceed “ that of the fine aggregate, nor is it greater than that of the cement, neither does it exceed 15% of the total solids in the mix. At least 15% of fine components must be present.
