Product Description
JK-1 High Range Water Reducing admixture (High Consistency)
Product Summary:
JK-1 the high consistency type of high range water reducing admixture is a concrete admixture with high performance which is purified by high range water reducing admixture of naphthalene series. It can prevent from the alkali-aggregate reaction because of the biggish alkali reactivity of aggregate or the alkali-aggregate reaction in the moist environment besides all merits of JK-1 high range water reducing admixture, the service life could be greatly increased, it’s a renewed popularized product in 21 century.

Principal Technical Performances:
1. The mixing amount is 0.5-1.2% of the cementitious material; the water-reducing rate is 15-30%.
2. Mixing the product, the concrete can save cement 15-20% in keeping the same workability and intensity; it can increase more than 10cm of the slump with the same combining rate.
3. This product has the obvious water-reducing dispersion effect which can improve the workability and the fluidity of concrete, make the smooth surface of concrete, and improve the encapsulation force of the concrete and the corrosion reinforcing steel bar in the situation of low water-cement rate.
4. This product has obvious early strength and reinforced effect, mixing powder 0.5-1.2%, concrete’s strength will improve 50-100% for 1 day, improve 40-70% for 3 days, improve 25-60% for7 days, improve 20-60% for 28 days.
5. This product is a high pure product with low alkali, low sodium sulfate. The low alkali content avoids the alkali-aggregate reaction of concrete. It has neither crystal nor sediment and it is suitable for automatic working.
6. This product is widely adaptable for cement, which can improve mainly the physical and mechanical performance of concrete, reduce the water thermalization of concrete, and improve clearly the anti-permeability of concrete without the influence to dryness of the concrete.

Applied Points of Technology:
1. The powder is calculated according to the cementitious material rate, liquid product is calculated by solid content, and water content will be minus from ratio.
2. Preferably use the later admixing; the extended admixing time is better for the uniformity.
3. This product is useable to prepare the antifreeze, which prevent effectively from sodium sulfate crystal.
