Concrete admixtures have become the fifth indispensable component of concrete. Throughout the development process of concrete and water-reducing admixtures, it can be found that the two promote each other and develop together. The development of new types of concrete admixtures has promoted the advancement of concrete technology, and the use of high-efficiency water-reducing admixtures has become an important milestone in the development of concrete technology.
Because of its good dispersion of cement and high water reduction rate, it is called a high-efficiency water-reducing agent. The high-efficiency water-reducing agent has a high water-reducing rate and an early strengthening effect. In addition to dispersion adsorption, its effect mechanism also has the electrical repulsion effect of the adsorption double electric layer. High-efficiency water-reducing agent has a high water-reducing rate and can promote the hydration reaction in the early stage of hydration. Hydration products are quickly deposited on the surface of cement particles, causing the Zeta potential to decrease, thereby greatly improving the fluidity of the concrete mixture and significantly improving the durability of the concrete. It can produce high-fluidity concrete, pumping concrete, and high-strength concrete. etc., which have very serious implications for large-volume concrete projects, offshore construction facilities, lightweight high-strength concrete components and finished products. This article specifically compares the properties of different superplasticizers and their impact on concrete performance.
