DS-J1 standard polycarboxylic acid high-performance water reducing agent is a new generation of high-performance water reducing agent produced by our company, which is green and environmentally friendly, with excellent comprehensive performance, and is suitable for compounding all kinds of multi-functional composite admixtures, and it can also be used directly for the preparation of all kinds of high-performance concrete.

Technical performance and characteristics

1, the product is light brownish red, brownish yellow or colorless transparent liquid, the product is non-toxic, non-combustible, non-corrosive, alkali content is very low, does not contain chlorine ions, the solid content of (40%~70%)±1%.

2, high water reduction, folding solid content of 0.1% ~ 0.4%, water reduction rate of up to 25% ~ 45%.

3, high slump, concrete 1 ~ 2h slump basically no loss, and almost unaffected by temperature changes.

4, high enhancement, concrete 3d compressive strength ratio > 160%, 28d compressive strength ratio > 140%.

5, good suitability for cement, adaptable to different types of cement, especially suitable for preparation of high durability, self-compacting and other high-performance concrete with fly ash, slag and other active admixtures.

6, the concrete anti-water secretion, anti-separation performance is good, concrete pumping resistance is small, easy to transport; concrete without large bubbles, small color difference, good quality of concrete appearance.

Usage

1, 20% solid content commonly used mixing 0,7% ~ 1.4%, the preparation of high-strength concrete, may be appropriate to increase the mixing amount. The actual dosage should be determined by trial mixing.

2、This product shall not be compounded with naphthalene water reducing agent, when it is used with other admixtures at the same time, concrete compatibility test should be carried out.

Packing and storage
