Abstract:The Siberian Metallurgical Institute (SMI) has developed low-cement concrete with acid and basic slags from a Russian foundry. The concrete contains neither natural aggregates (crushed stone, gravel, or sand) nor artificial porous aggregates (claydite, aggloporite, polystyrene, or others). It includes the following materials: 680 to 1140 kg/m 3 of acid slag sand form PTP with a particle size of 0 to 5 mm used as fine aggregate; cementitious materials (340 to 400 kg/m 3 of fine-grained basic slag and 100 to 170 kg/m 3 of M500 portland cement); 260 to 290 kg/m 3 of water; 0.3 percent by weight of cement of plasticizing admixture (technical grade lignosulfonate); and 1 to 2 percent of air-entraining admixture (secondary sodium alkyl sulfate). To make the wide application of this concrete possible in construction (mainly for low-rise cottages), deformation properties, protection of reinforcement from corrosion, frost resistance, and water and gas permeability were studied during a 1-year period. The investigation shows that concrete developed in this way complies with Russian international standards for low-strength concrete and can be used in housing construction. Air-entrained concrete for external walls should be protected by mortar or some other finishing material.
