On construction sites or in home improvement, 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 required in concrete. It also improves the strength and durability. This additive reduces the amount of cement required, lowers the cost and improves the quality of construction.
What’s the purpose of the water-reducing agent?
They include, in particular, the following elements
1. This water-reducing ingredient 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 water-reducing agents
Ordinary water-reducing agent (water reduction ratio) >= The main representative of lignosulfonate systems (sodium-lignosulfonate; calcium-lignosulfonate; magnesium-lignosulfonate etc.). ).
2 . Second generation water-reducing agent
High-efficiency water reducing agent >= 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 mixture of 25% polycarboxylic acids and water-reducing agents.
and , the water-reducing agents , play a major role in concrete. The agent will increase concrete’s durability and strength, as well reduce the concrete required to make it and cut down on costs. It is for this reason that water-reducing chemicals are essential in the construction industry.
