Abstract:
BASF has developed a liquid microsphere-based admixture. At a dosage of 1% by volume of concrete, this new admixture will protect concrete exposed to cyclic freezing and thawing under saturated conditions. Full-scale fields trials using ready mixed concrete from both dry-batch and central-batch plants show that microsphere-treated concrete is easy to place and finish.
