Abstract

1465521 Cementitious pipe NATIONAL RESEARCH DEVELOPMENT CORP 14 Jan 1975 [14 Jan 1974] 1573/74 Heading F2P [Also in Divisions B5 and E1] An internally tapered pipe comprises layers of fibre-reinforced cementitious material sandwiching circumferentially or longitudinally wound continuous rovings. Cement, gypsum or calcium silicate is reinforced with glass and/or asbestos and/or polypropylene chopped fibres, continuous fibres, and mats or meshes. Cellulose ether or methyl cellulose is added, with external pigments or texture aggregate.
