Senpu SP - YZ - 4 (liquid) aliphatic retarding effect of water reducing agent

Performance characteristics:

1. The enhancement effect: with reference concrete slump and under the premise of dosage of cement, such as water reducing rate can reach 15-17%, 3 to 7 days can improve the concrete 70 ~ 80%, 28 days strength 110% or higher.

2. The pumping performance: small concrete slump loss, the added value of 80 mm or more concrete slump, < 1 hour slump 20%, has the good pumpability.

3. The retarding effect, can significantly increase the mobility of concrete, improve the interoperability, can delay the cement hydration exothermic peak, avoid the construction into layer cold crack phenomenon, effectively improve the anti-cracking waterproof performance.

4. Work performance: improve the workability of fresh concrete, such as water retention and secrete water-borne operating performance.

Method of use:

This product dosage range of 1.5 ~ 2.5% (in gelled material flow meter), according to the adaptability of cement, concrete slump and the change of the temperature requirements, adjusted within the range recommended to determine the best dosage. When using this product, should according to the concrete test with test and the adaptability of cement in advance.

Scope of application:

This product is suitable for all kinds of mass concrete, high-rise buildings, elevated, highways, Bridges, hydraulic concrete and underground and underwater pouring concrete, etc.

Key points:

1. The change of varieties or new cement, cement cement compatibility test should be done.

2. Must be correct measurement test mixture ratio, and concrete should be in strict accordance with the construction specification operation.

3. For the retarded concrete, should according to the concrete test with test setting time in advance.

4. With conventional concrete engineering, must strengthen maintenance by construction standard.

5. The winter construction of concrete, besides the effect of admixture, at the same time must be covered with straw bag, plastic film freeze protection measures, such as strengthen maintenance according to the construction standard.
