摘要: The aim of this laboratory study was to evaluate the properties high performance porous concrete. It required no special vibration equipment and curing. optimum mixture proportions were used in preparation concretes containing three sizes coarse aggregates with appropriate amount water-reducing thickening (cohesive) agents. Tests carried out on concrete were: slump, slump-flow, void ratio, coefficient permeability, compressive flexural strengths, strength development rate. Furthermore, a test proposed determine effects agents self-compaction meant its hardened from viewpoint practical application. Its rate also examined at curing age 1, 3, 7, 14 28 days 20 °C 60% relative humidity (R. H.). Consequently, exhibited good workability cohesiveness segregation or bleeding, developed compared conventional results for showed without any compaction vibration.
