Product main performance

The products mainly implement the GB8076-2008 "concrete admixture" standard and the Ministry of Railways TB10424-2010 "railway concrete engineering construction quality acceptance criteria", all performances meet the above standard requirements.

The product has wide adaptability to cement, and the strength development advantage at low temperature is obvious. Especially in winter,when the temperature is low, it has better low temperature strengthening effect. The mold can be demolished under normal temperature ucring in 1 day, and the strength can reach 100% of the design strength in 7 days. Under the same condition of water-to-binder ratio, the strength of 28 days is about 20% higher than that of ordinary water-reducing agent. It can be used for pipe pile maintenance construction ,pumping concrete and super-flow self-compacting concrete. This product is conductive to speed up the construction progress of the project, saving labor and capital occupation. The product does not contain harmful components such as sodium chloride and sodium sulfate, and does not corrode steel bars, extending the life of the project.
