High Aluminium Cement Manufacturer Process

1. While preparing heat-resistant concret, aggregation should be selected properly. the gradation of aggregate should be appropriate to realize highest bulk density as well as suitable to cement material. Proportion of sand should be controlled within 40%60%. Proportion of ingredient could be decided according to the practical condition and is determined by trial mixing.

2. Manufacturing process could begin after the cement is unpacked and mixed with water in the determined ratio manually or by machine. The mixed mortar is better be used within 40 min. hydration heat of aluminium cement releases fasten on the early period. Thickness of each casting should be thinner than 3cm. after the concrete hardened, maintenance should be started immediately by watering. The maintenance should be no less than 3 days.

Matters Need Attention

1. During manufacturing, to avoid losing control of setting time, the cement shall not be mixed with cementitious materials such as silicate cement, lime, etc., which can precipitate calcium hydroxide. Before use, mixing equipment must be cleaned and washed.

2. If steam curing is used to accelerate the hardening of concrete, the curing temperature shall not be higher than 50 degrees.

3. The products, wrapped in woven bags, should be stored in a cool and dry place to prevent moisture and impurities.
4.  The long-term strength of refractory concrete will decrease greatly, and should be designed according to the lowest stable strength.
