Senpu SP - YZ - 5 (liquid) aliphatic early strength jianshuiji

Performance characteristics:

1. Early strength antifreeze: with reference concrete slump and the dosage of cement, such as water reducing rate can reach 15-22%, with significant early strength, prevent frostbite and strengthening effect, 60 ~ 80% 3 ~ 7 days strength, 28 days strength 100% or higher, suitable for winter construction under different temperature conditions.

2. 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%.

3. Job performance: can significantly improve the workability of concrete, water retention, and secrete water, improve the workability and avoid construction into layer cold crack phenomenon.

4. 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 1.5 ~ 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 early strength antifreeze of pumping concrete, mass concrete, high-rise buildings, roads, Bridges and hydraulic 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.
