What is the price of seaweed powder? Algae powder can improve the engineering quality. Seaweed powder can delay the setting time of cement, give mortar a high degree of water retention, avoid premature drying and bake on the wall with high water absorption, so it is equivalent to a cement reinforcing agent, which can give full play to the bonding strength and structural compactness of cement, thus ensuring the engineering quality. Algae powder is non-toxic and tasteless, harmless to skin and human body, and completely different from other chemical additives. (Wolf Waterproof will answer for you)
