| 内容記述 | Self-compacting concrete (SCC) has been developed over the past 25 years in order to improve the durability of concrete structures. The cement content in mix proportion of SCC must be approximately 2 times higher than that of conventional concrete, hence SCC cost is higher than that of conventional concrete. Air-entraining agent (AE), new-type superplasticizer, viscosity agent were added to the mix in order to reduce the interaction between coarse aggregate and mortar (1-Rmb/Rm) and to increase the sand to mortar ratio (s/m). This resulted in a reduction in cement content of the mix proportion. The interaction between coarse aggregate and mortar depend on various factors such as sand content (s/m), water to cement ratio (W/C), type of superplasticizer, amount of viscosity agent and type of air entraining agent. The interaction between coarse aggregate and mortar was reduced by adding viscosity agent in mix, however it is effective for mix proportion, which contain moderate W/C (32%-35%). Furthermore, the interaction between coarse aggregate and mortar can be reduced by using of new-type superplasticizer and new-type air entraining agent. These results demonstrated that sand content can be increased, which resulted in the decrease automatically in cement content by adding optimum amount of viscosity agent, using new-type superplasticizer and using new-type air entraining agent. | |||||||||
