The product obtained by grinding sulphoaluminate cement clinker, consisting of essentially anhydrous calcium sulphoaluminate. Suitable gypsum shall be blended with clinker during manufacture of low-alkalinity cement. The product has low alkalinity and small free expansion property. It is hydraulicity binding material. The code no is L-SAC.
The product carries out the standard: JC/T659-1997. The strength grade depends on its7 days compressive strength. There are three grades: 32.5, 42.5 and 52.5.
The product achieved a class second provincial prize of excellent new product, a class third provincial prize of improvement science and technology.
It is one of important new product of state. The item code is 98G041F6200009.
Main specifications
1. Specific surface area: ¡Ý400©O/kg.
2. Setting time:
Initial setting time: ¡Ý25 min.
Final setting time: ¡Ü180 min.
3. Alkalinity
To the cement paste under the condition C/W=10:1, the PH after hydrating 1 hour is less than 10.5.
4. Free expansive ratio:
Under the condition cement/sand=1:0.5, the free expansive ratio is 0.00%-0.15% in 28 days.
5. The strength in different age are not less than the following:
Grade Compressive strength (M pa) Bending strength (M pa)
1d 7d 1d 7d
32.5 25.0 32.5 3.5 5.0
42.5 32.0 42.5 4.0 5.5
52.5 39.0 52.5 4.5 6.0
Properties:
Besides the high early-strength property as rapid-hardening cement, low alkalinity cement has some other characteristics such as low alkalinity¡¢ small expansive ratio¡¢ short stability time¡¢ and small dry-shrinkage rate, compounded with glass fiber. It has high strength retaining ratio and longer work-time, so it is the special cement for making GRC products.
Applications:
The cement can be used to produce light-weight complex slab of internal and external wall, and GRC products such as corrugated tile, net-frame slab, ventilation duct, and some other structures.
Package and storage:
bulk and weave package with membrane, 50kg per bag, conservation in cool and dry place |
