Chang'an Renheng Bentonite Anti settling Agent is a widely used anti shrinkage agent in building materials such as cement, reinforced concrete, and mortar. It can effectively improve the fluidity and stability of cement mortar, reduce its shrinkage, prevent cracking and other problems, thereby improving the durability and service life of building materials. Here, we will provide a detailed introduction to the characteristics, application scope, and mechanism of action of bentonite anti settling agents.


1、 Characteristics of Bentonite Anti settling Agent

The main component of bentonite anti settling agent is bentonite with a chemical structure of 2SiO2 · Al2O3 · nH2O. It has strong adsorption and chemical stability, and can adsorb free ions and chemicals in cement, thereby preventing water loss and crystallization, and reducing cement shrinkage. At the same time, the particle specific surface area of bentonite anti settling agent is large, which can increase the surface tension of cement mortar, improve the fluidity and stability of mortar.


2、 Application scope of bentonite anti settling agent

Bentonite anti settling agent is widely used in various building materials such as concrete, wall mortar, ground mortar, waterproof materials, etc., especially in cement mortar of large-scale water conservancy and hydropower projects, with more significant effects. In addition, bentonite anti settling agent can also be used in the production of various refractory materials, friction materials and other special fields.


3、 The mechanism of action of bentonite anti settling agent

The mechanism of action of bentonite anti settling agent mainly includes the following aspects:

1. Adsorption: Due to the large surface area of bentonite particles, they have strong adsorption properties and can adsorb free ions and solutes in cement, while maintaining a balanced moisture concentration inside the cement mortar.

2. Enhance fluidity: Bentonite anti settling agent effectively improves the fluidity of cement mortar by increasing the dispersed phase inside the cement mortar colloid, reducing the attraction and gaps between particles.

3. Improving stability: The addition of bentonite anti settling agent can arrange the particles in the mortar, form a skeleton, enhance the flexural strength and stability of the mortar, reduce the shrinkage of the mortar, and greatly reduce the damage caused by shrinkage and cracking.


In short, bentonite anti settling agent plays a very important role in improving the performance of building materials and ensuring construction quality. In the future, with the development of social economy and continuous progress of technology, the research and application of bentonite anti settling agents will become a field with broad development prospects.

Chang'an Renheng Bentonite Anti settling Agent will continue to improve, and its products will be continuously innovated and integrated
