Abstract
High-fluidity concrete that has been developed recently seems to have several characteristics concerning the fluidity of raw materials. Therefore, data on pumpability of concrete need to be compiled and become useful statistics in this area of study. This report focuses on an experiment conducted on viscosity agent mixed concrete for determining the pumpability of it using portland blast-furnance slag cement. Here same types of raw materials are used where the water-cement ratio was made to vary in two different cases, high-fluidity concrete and the other normal concrete. Here concrete mixer truck was employed while the pumping distance was set at 25m and 100m. The analysis was made on factors like slump, air, pressure in pipe and pressure loss.
