CURING OF CONCRETE IN HOT ENVIRONMENTS - ASSESSMENT OF THE EFFICIENCY OF CURING MEMBRANES BY MEASURING PERMEABILITY AND PORE STRUCTURE . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.

Curing is the process which ensures that concrete is maintained saturated or nearly saturated while it hydrates. This paper presents a study of the evaluation of the effectiveness of four curing membranes (solvent-borne resin, wax emulsion, solvent borne acrylic and acrylic emulsion) under simulated Middle Eastern climatic conditions. The cement used throughout was ordinary Portland cement (castle cement), the coarse aggregate used was quartzitic gravel and the fine aggregate used was obtained from North Nottinghamshire and had a maximum size of 2.36 mm. Three concrete mixes with nominal cement contents of 270, 360 and 450 Kg per cubic metre, constant to fine total aggregate ratio of 0.39 and constant water/cement (w/c) ratio of 0.48 were used. Corresponding mortar mixes were made by eliminating the coarse aggregate fraction while keeping the same w/c ratio. The evaluation was carried out by direct measurements of permeability profiles of concrete slabs cured with and without membranes. Some experimental results obtained in a laboratory investigation for moisture loss, compressive strength, porosity and permeability are presented and discussed.(A) For the covering abstract of the conference see IRRD 828897.
