DS-J4 slow-release polycarboxylic acid high-performance water reducing agent is characterized by high water reduction, high slump-proofing, high reinforcement, low dosage, significant slow-release effect and good cement adaptability, etc. It is suitable for the preparation of commercial concrete, high-strength concrete, fluid concrete, self-compacting 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 gas ions, the solid content of (10%~30%)±1%.

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

3, high enhancement, concrete 3d compressive strength ratio of more than 160%, 28d compressive strength ratio of more than 140%.

4、High retardation, retardation effect is remarkable, slump loss through time:1h:<-70mm;2h:<-60mm;3h:<-60mm and >-120mm.

5, good applicability to 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, good performance of anti-water secretion and anti-separation of concrete, low resistance to pumping of concrete, easy to transport.

7, trace air-entraining, concrete gas content of 3% ~ 5%, air-entraining volume can be adjusted according to user requirements.

Usage

1, the actual use of mixing should be determined by trial mixing. 25% solid content commonly used mixing 0.7% ~ 1.2%, 12% solid content commonly used mixing 1.5% ~ 2.5%, the preparation of high-strength concrete, can be appropriate to increase the amount of 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

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 water evaporation, and prevent from exposure to sunlight and frost.
