Title from cover. Includes bibliographic references. "Changes in physical properties of about 400 concrete test specimens, made with aluminous cement and expanded shale, anorthosite, ilmenite and phonolite aggregates, were studied after exposure to temperatures ranging from 100 to 1100°C. It was found that the aluminous cement concrete loses its strength rapidly in the range of temperatures investigated. Expanded shale aggregate concrete showed the greatest stability, retaining about 20 per cent of its original compressive strength after firing at 1000°C, whereas concrete made with phonolite aggregate was the least heat-resistant of the four types investigated"--Synopsis.
