Pumping agent is an important concrete admixture polycarboxylate liquor manufacturers, is an important pillar industry of new building materials products. Pumping agent not only greatly improve the mechanical properties of high strength concrete, and provides a simple and easy construction process. Our first application of pumping water reduction rate of more than 5% less than 10% of the ordinary pumping agent, such as sodium rosin, lignin sulfonate and soap acid. But because of its low water-reducing Yunnan polycarboxylate liquor, limited engineering applications quickly replaced by other reasons. Concrete expansion GQ-209 concrete expansion implementation of standards: GB23439-2009GQ-208 concrete expansion feature is to change the internal structure of concrete, enhance the density, improve concrete cracking, seepage capacity, reduce shrinkage. Suitable for cracking, seepage, joints, prestressed, high performance, such as filling the need to compensate shrinkage concrete projects. ◎ Specifications: ◎ The main technical performance: ◆ 3 days, 7 days, 28 days compressive and flexural strength increased by 10-30% compared to the reference concrete, the late strength continued to grow. ◆ impermeability grade is 1-2 times the reference concrete, up to more than S30. ◆ no corrosion of steel polylactic acid liquor content of water pollution. ◆ bleeding, slump loss corresponding reduction does not affect the setting time. Polylactic acid liquor _ high-strength building materials (online consultation) _ polylactic acid liquor by Linyi City Building Material Co., high-strength.
