Abstract
In this study, in order to confirm the applicability of Hollow Glass Powder(HGP) in 70MPa-class high strength concrete, the fresh and hardened states were examined according to the amount of HGP, and the results are as follows. The flow characteristics showed that the slump flow increased slightly as the amount of HGP was increased, and the T500 was slightly shortened as the amount of HGP was increased, and the rebar passing ability was improved due to the ball bearing effect of HGP. In particular, it showed the best rebar passing ability at a usage of 1.0kg/㎥. The use of HGP 1.0kg/㎥ resulted in a 40% reduction in plastic viscosity, but the viscosity increased at 2.0kg/㎥. Through experiments, it was confirmed that HGP was helpful in improving the workability of high-strength concrete, and the usage of 1.0kg/㎥ is considered to be the most appropriate. It was confirmed that HGP does not affect concrete compressive strength.
