Water reducing agents are mainly used in the construction industry. What is the role of water reducing agents in pumping concrete? Adding water reducing agents to concrete can effectively save the amount of concrete. The integrated concrete mixing machine is suitable for rural and urban areas. Both on-site pouring design and construction provide high construction efficiency, increase the competitiveness of peers, save manpower and material resources, and also make concrete transportation safer and the transportation distance higher and farther. During construction, we often pump concrete Add water reducing agent.
Uses of water reducing agent
1. Without changing the ratio of various raw materials (except cement) and the strength of concrete, the amount of cement can be reduced and the quality of cement can be added 0. 2% ~ 0. 5% concrete water reducing agent can save more than 15 ~ 30% of the cement amount.
2. Without changing the ratio of various raw materials (water removal) and the slump of concrete, reducing the amount of water can greatly improve the strength of concrete. The early strength and late strength are respectively Concrete without water-reducing admixtures can be improved by more than 60% or more than 20%. By reducing water, it is possible to pour C100 grade high-strength concrete
The role of water-reducing admixtures in pumping concrete
1. Literally speaking, water reducing agent is the amount of water required to reduce the concrete to a certain slump. Using less water to achieve the desired slump means that the water-cement ratio is effectively reduced. Thereby unimpeded to improve concrete strength, water density and durability of concrete pumping. It is mainly used to improve the fluidity of concrete and improve pumping performance.
2. The basic principle of water reducing agent is to improve the cohesion of cement, improve concrete pumping skills, make it a dispersed structure in a short time, improve fluidity, and thereby achieve the purpose of water reduction. Polycarboxylate water-reducing agent is a high-performance water-reducing agent and a cement dispersant used in cement concrete applications. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. Chemically, it can be divided into two categories: the main chain is methacrylic acid, the side chain is carboxylic acid group and MPEG, and the polyester structure.
In summary, we can understand the role of water-reducing admixture in pumping concrete. We can also use it better when using water-reducing admixture in the later stage. I will share it here today. Hope this helps.
