DS-J3 early-strength polycarboxylic acid high-performance water reducing agent has the characteristics of high water reduction, high slump preservation, high reinforcement, low admixture, good cement adaptability, etc. It is suitable for the preparation of commercial concrete, high-strength concrete, fluid concrete, self-compacting concrete, precast concrete and large-admixture concrete.
Technical performance and characteristics
1, the product is light brownish red, brownish yellow or colorless transparent liquid, the product is non-toxic, non-flammable, non-corrosive, alkali content is very low, does not contain chlorine ions, solid content of (10%~30%)±1%.
2, strong plasticizing function, can make the concrete slump from 3~7cm increased to more than 20cm, water retention, adhesion and pumpability significantly improved.
3, high slump, concrete 1 ~ 2h slump basically no loss, and almost unaffected by temperature changes.
4, high early strength and high reinforcement, concrete 1d compressive strength ratio ≥ 180%, concrete 3d compressive strength ratio > 170%, 28d compressive strength ratio ≥ 140%.
5, good suitability for cement, adapt 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、It has certain air-entraining property, the air content of concrete is 2%~4%, the concrete has good resistance to water secretion and segregation, and the pumping resistance of concrete is small, which is convenient for transportation.
Usage
1, the actual use of mixing should be determined by trial mixing. 25% solid content commonly used mixing 0.7% ~ 1.5%, 12% content commonly used mixing 1.5% ~ 2.5%, the preparation of high-strength concrete, may be appropriate to increase the amount of mixing. 2, the product shall not be compounded with naphthalene water reducing agent, when used with other admixtures at the same time, should be tested for concrete compatibility.
Packing and storage
1、It is packed in 200kg~1000kg barrels or shipped by tanker truck.
2、Store in clean plastic, fiberglass or stainless steel containers, iron containers are not suitable for storage. Avoid rain and evaporation of water, prevent exposure to sunlight and frost. 3, the shelf life of the product is 1 year, over the period of qualified inspection can continue to use.
