Senpu SPGSM - type 3 (liquid) modified aliphatic high efficiency 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 be up to 16 ~ 25%, periods of age concrete strength were significantly improved, 3 ~ 7 days compressive strength than about 80 ~ 90%, 28 days strength still can be improved by about 30%.

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 < 20%, extending degree of > 500 mm, self-leveling, ofnon-vibrating concrete can be produced.

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: significantly 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 setting time) the tensile and flexural strength of 28 d requirements.

Method of use:

This product dosage range of 1.5 ~ 2.6% (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 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.
