Lightweight Aggregates How Do You Make the Right

Lightweight Aggregates How Do You Make the Right Decision? It is not recommended that dry lightweight aggregate be directly batched and mixed because the aggregate particles can continue to absorb water from the mix This can cause the mix to segregate or stiffen before it can be placed Get price
