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 chemical additive that reduces water, has a main component called a surfactant. It can significantly reduce the amount water required to make concrete. Using this addition can reduce the cement needed, lower the cost, and improve quality.

What's the function and use of 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 water inside 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

Ordinary water-reducing agent (water-reduction rate) >= Also called plasticizer (also known as lignosulfonate), it is a main component of the system of lignosulfonates (sodium, calcium, and magnesium lignosulfonates, etc.). ).

2 . Second generation water-reducing agent

High-efficiency water-reducing agents (water reduction rate >= The main representative of naphthalene systems, aminosulfonate systems, and aliphatic sytems.

3 . Third generation water reducing agents

Water-reducing agent with high performance (water-reduction rate). >= This is the most common polycarboxylic acids (water-reducing agent), which can be divided in three categories: Early-strength Type, Standard Type, and Slow-Setting Type.

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 an important chemical component in construction.
