Performance characteristics:

1. The enhancement effect: with reference concrete slump and the dosage of cement, such as the premise of water reducing rate is greater than 35%, concrete age strength were significantly improved, 3 ~ 7 days compressive strength than about 140 ~ 150%, about 20% strength of 28 days can still improve the quality of products.

2. The pumping performance: has significant pumpability. Compared with the reference concrete, on the premise of the same water-cement ratio, the net gain of a slump of 100 mm, or 2 hours slump loss rate < 15%, extending degree of > 500 mm. Configurable self-leveling, ofnon-vibrating concrete.

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.

5. The surface is bright and clean, the mixing of concrete with this product, with strong adhesiveness, less air content and low exudation rate, etc, can effectively improve overhead, highways, Bridges and other kinds of concrete surface is bright and clean and beautiful.

6. Tensile, bending, this product has the function of retarded before early strength in ensure the premise of content, can meet the 3 d of concrete (with the exception of retarded time) the tensile and flexural strength of 28 d requirements.

Method of use:

When using this product for water reducing agent distribution, although compared with common naphthalene series water reducing agent, has good compatibility, also should be the compatibility of cement inspection. Individual cement likely water reducing rate is low, the phenomenon such as a big slump loss, suggested by properly increasing the dosage, compound with other components of retarded or after mixing method. Mixed after using this product, the air content of concrete increases slightly (1.0%), to improve the workability and durability of concrete.

Scope of application:

This product is suitable for all kinds of pumping concrete, mass concrete, high-rise buildings, elevated, highways, Bridges, hydraulic concrete and underground and underwater pouring concrete, etc. Particularly suitable for key projects and have special requirements of concrete.

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.
