JF CALCIUM LIGNO SULFONATE Product Description:
Synonyms: Calcium Lignin
Calcium lignosulfonate free water evaporation leaves fewer pores, the internal structure is compact, and the reduction of porosity is obviously beneficial to the improvement of concrete strength, improves the size and distribution of the pore structure of cement, and retards the growth rate of crystals. , The crystal grows more fully, so more fibrous crystals are interspersed with each other to form a strong network structure, so that the strength of concrete is significantly improved.

CLS Impact On Cement Hydration:
1. Adding CLS can greatly delay the heat release of cement hydration. When the CLS content is 0.5%, the maximum hydration temperature of the cement paste system can be reduced by ℃ compared with the blank, and the time to reach the maximum temperature is delayed by 10 hours.
2. The amount of chemically bound water in the cement paste increases with the increase of hydration age. CLS mainly inhibits the increase of chemically bound water within 3~10h. The higher the amount, the greater the effect. After 1d, the inhibitory effect of CLS on hydration is gradually eliminated, and it can even increase the later hydration degree of cement.
3. High content of CLS can promote the formation of ettringite in hardened cement and inhibit the early formation of CSH, but it has five effects on the later formation of CSH.
4. The addition of CLS inhibits the growth of the crystal form and structure of the cemented product, making it difficult for the CSH gel to form a spatial grid, and the ettringite crystals become finer, but it does not change the chemical composition of the ettringite.
5. The total pore volume and average diameter of hardened cement paste decrease with age.
