SELF COMPACTING-CONCRETE – POSSIBLE APPLICATION IN INFRASTRUCTURE OF VILLAGE
Keywords: Self-compacting concrete, aggregate selection, sand point, Chinese mix design of SCC, flyash
Abstract: Self-compacting concrete (SCC), increasingly popular in Japan, USA and western countries of Europe, is an accepted structural material for the future. More and more common use of in engineering objects (congested reinforcement elements, foundations, bridge piers, slabs, tanks, precast industry) makes it possible to apply SCC technology in the village infrastructure. Particular advantages, regarding both fresh concrete (elimination of vibration) and hardened concrete (high strength and durability) and also economical aspects seem to be especially prosperous. Elimination of vibration is achieved by the proper choice of SCC constituents, including high effective super plasticizer, compatible with cement and mineral fillers, such as fly ash, silica fume, etc. The correct selection of the aggregate seems to be an important aspect of SCC technology as well. The aggregate is one of particularly changeable component of the concrete, taking into account its origin. Hence, the development of a suitable procedure for design of the aggregate stock is the essential issue in SCC technology. The paper presents results of studies on self-compacting concrete mixes designed at the different quantitative relation between the coarse and fine aggregates. Particular attention was paid to the value of sand point (30, 35, 40, 35%). The authors tried to verify Chinese mix design method for SCC, decreasing the amounts of cement. The properties of fresh concretes (initial slump, slump-flow, air content) and hardened concretes (compressive strength) were compared and analyzed.
