Types of concrete admixtures

There are many types of concrete admixtures with diverse functions, including high-performance water-reducing admixtures (early-strength type, standard type, retardant type), high-efficiency water-reducing admixtures ( Standard type, retarding type), ordinary water reducing agent (early strength type, standard type, retarding type), air entraining water reducing agent, pumping agent, early strength agent, retarder, air entraining agent, antifreeze, Expanding agent, waterproofing agent and accelerating setting agent, etc.

The main functions of concrete admixtures:

1. To improve the fluidity of concrete mixtures Admixtures;

2. Admixtures that adjust the setting time of concrete and harden the performance of Hanli Education Tuition;

3. Admixtures to improve the durability of concrete;

4. Admixtures to improve other properties of concrete;

5. Improve the bonding force at the interface between aggregate and mortar, and improve the holding force between steel bars and concrete.

Precautions for the use of admixtures:

1. The variety of admixtures should be based on the engineering design and construction requirements

2. It is strictly prohibited to use admixtures that are harmful to the human body and pollute the environment

3. For reinforced concrete and marine concrete with durability requirements, attention should be paid to the chloride ion content and the amount of alkali</p
