What is the role of concrete mud inhibitor? In construction tests, it is mainly a new type of admixture that improves concrete's slump loss due to high mud content in sand and gravel. It is a colorless, transparent liquid with a pH value of 6 to 9. According to relevant information, the mud inhibitor is composed of soil dispersion components, soil adsorption components and ionic complex components. It has the following functions:
(1) It can be adsorbed on the surface of soil particles and reduce the amount of soil particles. The water absorption rate of the particles. At the same time, the branched chains of the mud-resistant polymer can effectively reduce the possibility of soil particles getting close to each other and settling into gels, thereby making concrete with high mud content have good fluidity and reducing concrete collapse caused by high mud content in sand and gravel. Drop loss ensures the working performance of concrete.
(2) For concrete with the same mud content, compared with ordinary admixtures, it can significantly reduce the dosage of admixtures and reduce concrete production costs.
(3) It can reduce the impact of high mud content in sand and gravel on the strength and durability of concrete, and has no corrosive effect on steel bars. The formula of the mud inhibitor varies depending on the mud content of the sand and the mineral composition of the soil. Add 10 to 15kg of polycarboxylate high-efficiency water-reducing agent (8% concentration) per ton. Generally, the mud content of sand is less than 10%. Using mud inhibitor, concrete can be prepared with basically no loss of fall within 2 hours. According to the test data statistics of concrete companies that use mud inhibitors, the strength values of concrete at each age of 7 days, 28 days, and 60 days develop normally.
The role of concrete mud inhibitor
1. During the construction process of construction projects, the use of admixtures can effectively improve the construction environment and facilitate the use of various mechanical equipment. Reduce the workload of relevant construction personnel and ensure project quality.
2. Successfully complete construction tasks in some harsh environments. Concrete admixtures can significantly shorten the maintenance time after construction, thereby speeding up the demolition of project formwork, enabling faster turnover of formwork, and significantly speeding up the subsequent steel bar tensioning and shearing, thus shortening the entire project period. Greatly shortened.
3. The addition of concrete admixtures can also effectively improve the overall quality of the concrete project and improve its strength, durability, frost resistance, and impermeability.
4. It can significantly improve the drying shrinkage of concrete and the flow properties before solidification. In construction projects, if concrete admixtures are used correctly, admixtures will usually not be used in concrete construction. Quality makes no difference.
5. Under the premise of scientific use, the use of cement and various auxiliary materials can be greatly reduced. The reduction in the use of cement-based auxiliary materials not only saves social resources, but also saves the construction process. Chen Ben, and facilitated the subsequent tamping and smoothing process.
Therefore, during the construction process of construction projects, the rational use of concrete mud inhibitors can not only effectively improve the quality of the project, but also enable construction to be carried out from a more economical and reasonable perspective, making the construction of the project twice the result with half the effort.
