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 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 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. These agents can reduce the number of pores in concrete and improve its durability.
The evolution of water-reducing agent:
1 . First generation of water-reducing agents
Ordinary water-reducing agent (water-reduction rate) >= The main representative of lignosulfonate systems (calcium lignosulfonate and magnesium lignosulfonate) is sodium lignosulfonate. ).
2 . Second generation water-reducing agent
High-efficiency water-reducing agents (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 type and the slow-setting kind.
and , the water-reducing agents , play an important part in concrete. The agent will not only improve the durability and strength, but it will also reduce the concrete needed to achieve that. It is for this reason that water-reducing chemicals are an important chemical component in construction.
