Retarders

CMT-107 can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.

CMT-106 can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.

CMT-105 dissolves in water quickly owing to its strong hydrophilic property.It can absorb on the surfaces of the cement slurry hydrate to inhibit contact with water and chelate with Ca2+ to prevent crystal nucleus forming early. Therefore, it can retard thickening time.And,it can enhance the last strength of the cement stone because C3A shows weak adsorption performance.

CMT-104 can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry
