Concrete pumping agent -1BS
Characteristics and instructions：
Concrete pumping agent-1BS is composed of the Chinese Academy of Sciences Guangzhou chemical limited company research and development and production, both retarding and early strength of two kinds of characteristics. The product has a good adaptability to cement, easy to use, suitable for the construction of various concrete structure, especially suitable for high strength (ultra high strength pump concrete engineering goods). The use of this product concrete workability, can pump performance, the material can be prepared by self leveling, free vibration and high fluidity concrete.
The product has strong adaptability and can be used for a variety of Portland cement, and expansive agent and fly ash admixture compatibility, function complement each other, help to improve the properties of concrete. It can be widely used in industrial and civil buildings, highways, bridges, and other high strength concrete construction.
The product performance is stable, non-toxic, no stimulation, no radioactivity, no combustion and explosion, using process squadron human health and harmless, on the environment pollution-free, non chlorine salt, of reinforced no rust role. Products of good uniformity, no delamination, no precipitation, no crystallization in winter.
Performance characteristics:
1. this product is liquid, the concentration of 30%;
2. mortar water reducing rate is greater than 20%;
3. the strength of concrete at different ages can be increased by 30%-80% respectively.
4. this product can significantly increase the density, reduce the shrinkage and creep of concrete, improve the durability and prolong the service life of concrete;
5. according to user base flexible pumping agent to achieve optimum compatibility, concrete.

Application:
1. suitable for the long distance transportation of commodity concrete, mass concrete, concrete construction;
2. adaptation in hot summer areas, high temperature environment construction;
3. suitable for requirements of small concrete slump loss;
4. configurable C30-C60 concrete.
Application method
1. recommended dosage is the weight of cementitious materials 1.5%-2.5%; optimal dosage can be determined by test;
2. adding ways: concrete mixing, and mixing water together with the mixer, stir well;
3. before using the proposed test series, match test, in order to play the best products.
Notice
1. Different varieties of cement, required by the test to use;
2. In the same concrete mix proportion, when used with other additives compound, should be determined by field test its compatibility;
3. The construction should be careful to check the accuracy of the measurement.
Package and transportation：
1.Using tanker transport.
2.The stable performance, long-term storage is not hierarchical, no precipitation, no crystallization winter.
3.This product should be stored in clean plastic containers or metal containers through embalmed avoid foreign matter; valid for one year, the product expires after passing by concrete test can still be used.
