There are so many concrete admixtures, such as retarder and reducing agent, what are their functions?
1. The working principle of concrete water-reducing agent: Water-reducing agent is usually a surfactant, which is an anionic surfactant. It is adsorbed on the surface of cement particles so that the p…
What are the main components of concrete retarder, and what are their main functions?
There are many kinds of retarder, including sugar, lignosulfonate, hydroxy acid, inorganic salt and so on. Set Retarder is an additive that reduces the hydration rate and heat of hydration of cement o…
What is the difference between high-efficiency retarder and retarder, and what are their benefits?
The role of high-efficiency retarder is to maintain good slump and fluidity of concrete. Set Retarder is an additive that reduces the hydration rate and heat of hydration of cement or gypsum and prolo…
Factors affecting the adaptability of water reducing agent and cement and their solutions
In recent years, concrete admixture technology has developed rapidly. Due to the wide variety of concrete admixtures with different properties, the characteristics of construction projects and the act…
What are the types of commonly used water reducing agents and what are their characteristics?
At present, high-efficiency water-reducing agents mainly include lignin-based, naphthalene-based, resin-based, molasses-based and polycarboxylate water-reducing agents. Each type also includes air-ent…
