Flowing Concrete - Concrete Construction

1982/5/1  If it flows so well, doesn't it segregate? Is it really as strong as concrete made with a lower slump? A.: So-called flowing concrete is concrete that is made to a slump that is temporarily higher than normal. It is usually made by adding admixtures after the concrete arrives at the job site at a slump, for example, of 2 inches.احصل على السعر
