Concrete superplasticizer is also known as high range water reducer. They belong to the synthetic water-soluble organic substances that reduce the amount of water require to achieve a certain stability of concrete, reduce water-cement ratio, reduce cement content and increase slump. By the way, BTA 5300 superplasticizer is suitable for prefabricate and cast-in-place reinforced concrete in various industrial and civil construction, water conservancy, transportation, port, municipal and other projects. Besides, it can be used for the water-reducing and reinforcing components of various composite admixtures. More importantly, the water reducing ratio can be up to 25%.
