the net weight of bagged cement is 50kg, and shall not be less than 98% of marked weight. the total mass of 20 random bags should not be less than 1000kg. the packaging can be changed by consultation. special attention should be paid to moisture protection and not mixed with other varieties of cement in the transport and storage, stored period not exceeding for three months and expired or damp clotting, should be re-tested before being used.
1) during the construction, do not mix it with aluminate cement and lime that has hydroxide the cementitious material, and before using the mixing e must be washed clean.

2) do not be used in alkaline solution engineering.

3) it should be immediately watered for conservation from the beginning of hardening.

4) the concrete curing temperature shall not exceed 50 ℃ when accelerating the hardening of refractory cement.

5) when used for steel reinforced concrete, the protective layer thickness should not be less than 60mm.

6) do not add any external material if not tested.

7) do not contact with any non-hardening portland cement.
