On construction sites or in home improvements, we see concrete being used a lot. It is important to add a water-reducing additive to concrete. Why is it necessary to add water-reducing agents to concrete and what are the functions and mechanisms of this additive. The answers will be revealed next.
What is water?
A surfactant is the main chemical component of water reducing agents. Water reducing agent can be used to reduce the amount water needed in concrete. It also improves the durability and strength of concrete. This additive reduces the amount of cement required, lowers the cost and improves the quality of concrete.
What’s the function and use of the water-reducing agent?
They include, in particular, the following elements
1. This water-reducing additive contains a surfactant which can be used to spread cement particles. It will reduce the need for water.
2. Agents that reduce water can have a dispersing effect on the concrete, preventing it from drying out and settling.
3. Reduced water absorption: These substances reduce the number of pores in concrete and improve its durability.
The evolution of water-reducing agent:
1 . The first generation of water-reducing agents
Water Reducing Agent (Water Reduction Rate) >= Also called plasticizer (also known as lignosulfonate), it is a main component of the system of lignosulfonates (sodium-lignosulfonate; calcium-lignosulfonate; magnesium-lignosulfonate). ).
2 . Second generation water-reducing agent
High-Efficiency Water-Reducing Agent (Water Reduction Rate) >= The main representative of melamine systems, aminosulfonate systems, and the aliphatic system.
3 . Third generation water reducing agents
Water-reducing agent with high performance (water-reduction rate). >= It is a water-reducing polycarboxylic agent that can be classified into three different types, namely the early-strength kind, the standard kind, and the slow-setting one.
and , the water-reducing agents , play an important part in concrete. The agent will increase concrete’s durability and strength, as well reduce the concrete needed to make it and cut down on costs. It is for this reason that water-reducing chemicals are essential in the construction industry.
