CALCIUM LIGNOSULPHONATE USE AS BUILDING WATER REDUCING AGENT
Calcium Lignosulphonate
Application of calcium lignosulfonate
It is suitable for concrete, high mobility concrete, pumping concrete ten, concrete ten products and concrete ten construction in summer as well as delay concrete, concrete pile, concrete pile flume, hand dug pile concrete and underground mass concrete construction special requirements, with good economic benefits.
Effect on flocculation of finished concrete
① Because calcium lignosulfonate can reduce the water-cement ratio of concrete mixing, it can also greatly reduce the porosity of concrete, so that the structure is more dense, and the compressive strength is significantly improved.
② In the air entraining action of calcium llignonate, many fine bubbles are produced in the process of concrete mixing, blocking the capillary channel in concrete, thus improving the permeability of concrete, on the other hand, the water-ash ratio is reduced, increasing the compactness of concrete, but also improving the permeability of concrete.
③ The uniform distribution of fine bubbles formed inside concrete by the enventing action of calcium lanceolate can adjust the volume change caused by the temperature change, provide a certain expansion space for frozen ice crystals, effectively absorb the frost swelling stress generated by concrete and not cause damage, and the reduction of water-cement ratio also reduces coagulation. Free water in capillary, thus improving the freeze-thaw resistance of concrete.
The use of calcium lignosulfonate
1. The recommended dosage is 0.25-0.50% of cement weight, and the recommended dosage is 0.25%.
2 powder can be directly added to cement, sand, gravel dry mix, even after mixing with water, the mixing time should be extended to avoid uneven mixing. The powder can be prepared in advance in a solution of a certain concentration and added in liquid form, but care should be taken to deduct from the total water consumption of the coagulant.
3. Use this product according to the specific construction conditions (construction season, construction materials, etc.) by referring to the description of the concrete 10 mixture for necessary tests to obtain the best results.
