What kind of admixtures are used for different kinds of concrete

Concrete, as an indispensable material in construction engineering, is widely used in different parts because of its various characteristics. In this, retarder plays a key role, like a metronome in a dance, to ensure that the concrete remains in the best condition in the complex and changeable construction environment.

When we face various parts of concrete, such as beams, columns, walls, foundations, etc., as well as different types of cement, such as Portland cement, ordinary hardening cement, fast hardening cement, etc., how to choose the right retarder has become an important issue.

For cement containing high alkali, sulfide or too fine, the role of retarder is particularly prominent. It can effectively delay the hydration heat reaction, control the water requirement, and then adjust the strength and shrinkage of concrete. In low alkali cement, the addition of retarder is more seasonal factors.

When we delve into the types of retardants:

1. Dispersion retarder mainly solves the problem of concrete loss, it can effectively enhance the dispersion of concrete, make it more smooth in construction and reduce waste.

2. Viscosity retarder is focused on solving the workability of concrete, by increasing the viscosity of concrete, so that it can maintain good working condition under various environmental conditions.

3. Compound retarder is a versatile agent, it can adjust the working performance of concrete, make it adapt to a variety of construction requirements, but also provide more options for engineers.

In general, choosing the appropriate retarder is like finding the right partner for the concrete dance, only the perfect cooperation between the two can ensure the smooth progress of the construction project, and also provide a solid guarantee for the long-term use and safety of the project.
