Performance of
SUPERSLUMP-PR
SUPERSLUMP-PR
is used as slump retention agent. Therefore, SUPERSLUMP-PR
must be used with SUPERSLUMP-PC by appropriate ratio. As the
initial fluidity of concrete decreases, the ratio of
SUPERSLUMP-PR to SUPERSLUMP-PC should be increased to
maintain slump or slump flow with time. In contrast, less
SUPERSLUMP-PR is required in case of high fluidity concrete
(SUPERSLUMP-PC alone shows excellent slump retention
effect).
