ASD-2 is a non lead gas superplasticizer basedon aliphatic, which is non chlorine salt, non corrosive, brown red liquid, whichhas been formulated to comply with the requirements of GB8076-2008, GB8077-2000inChina.ASD-2 is compatible with the requirements of EN934-2 (Table 3.1 and 3.2) andASTM C 494 for Type F high range water reducing admixtures. ASD-2 is accordantwith all cements meeting recognized international standards.
1. Compared with naphthalene superplasticizer,the product has a significantly reduced water dispersion effect, the dosage1%-3% of cement usage amount has 15%-30% water reducing rate. The product canimprove the fluidity of cement paste in the case of low water cement ratio.
2. The product has better adaptability tovarious cement, can significantly improve the plastic and reduce slump loss.
3. The products have a strong remarkableeffect in early stage. the concrete can improve the strength of 60%-80% in 3days, 50%-80% in 7 days, 30%-50% in 28 days at same cement usage amount andsame slump; the growth of the strength will be maintained in the future.
4. In the same condition of originalstrength of the concrete and same slump, the product can save cement usageamount about
