Abstract:
A new family of polycarboxylate polymer admixtures enables the production of control flow concrete. Control flow concrete is produced using mixture proportions typical of conventional concrete. While it has the same segregation resistance as conventional concrete, it flows more readily and has high passing ability through congested reinforcement.
