Performance characteristics:

1. The enhancement effect: with reference concrete slump and under the premise of dosage of cement, such as water reducing rate can be up to 16 ~ 18%, concrete age strength were significantly improved, 3 ~ 7 days increase 70 ~ 80%, 28 days can still improve 15-30%.

2. The pumping performance: has significant pumpability. Compared with the reference concrete, on the premise of the same water-cement ratio, slump the added value of 100 mm, or 2 hours slump loss rate < 20%.

3. Impermeability index: reduce water consumption, increase the self-compacting concrete, compared with the reference concrete, the permeability performance can be improved by more than 50%.

4. 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.

5. The surface is bright and clean, the mixing of concrete with this product, its viscosity, air content, and secrete water phenomenon is effectively improved, and make all 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 needed for 3 d tensioned concrete strength (with the exception of retarded time) and improve the flexural strength of 28 d requirements.

Method of use:

This product dosage range of 1.7 ~ 2.2% (in gelled material flow meter), according to the change of and the adaptability of cement, temperature and concrete slump requirements, etc., within the scope of the recommended adjustment to determine the best dosage. Can be directly to powder mixed with, also can use the mixture solution. On-site mixing, extend 30 seconds, commodity concrete without extended mixing time. When using this product, should according to the concrete mixture ratio test and the adaptability of cement in advance.

Scope of application:

This product is suitable for all kinds of pumping concrete, mass concrete, high-rise buildings, roads, Bridges and hydraulic engineering, underground engineering and other kinds of pumping construction of concrete, also suitable for underground and underwater pouring 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.
