Why should continuous-grained stones be preferred when pumping concrete?
Because when the maximum particle size of stones is the same, the void ratio of a single particle size is larger than that of a continuous particle size, large voids must be filled with mortar. Under …
Concrete anti-crack density agent Siliceous density agent Concrete density agent Concrete admixture
Anti-cracking compacting agent is a new generation of special concrete material, which is compounded by a variety of inorganic salts rich in cement activity and strengthening components through scient…
Air-entraining water-reducing agent, concrete anti-freeze-thaw cycle JH anti-freeze cracking admixture
