Concrete Admixture For Concrete Performance And Effect Improvement

The traditional way of using concrete cannot save the amount used and is not conducive to the control of construction costs. Through the use of concrete admixtures, it is possible to achieve an improvement in all aspects of concrete performance, and it is possible to reduce the amount of concrete used to a certain extent. This promotes the development of energy-saving performance of concrete. For example, in the construction of a project, if some specific energy c3s, c3a, etc.. are used to improve the performance of concrete, and slag is used as part of the raw material, the amount of concrete can be reduced while ensuring the strength of concrete. The stability of concrete. At the same time, the weight of concrete itself is reduced.

Concrete admixtures have certain adverse effects while improving the performance of concrete. For example, when the admixtures are added in unscientific amounts, the performance of concrete will be greatly reduced. When the dosage of ordinary retarder is too much, on the one hand, it will lead to the concrete not caking for a long time, and on the other hand, it will affect the moulding effect of concrete. On the other hand, it is also not conducive to the improvement of concrete strength, which brings some hidden problems of project quality. In addition, when used in various types of admixtures, due to improper control of the amount used, or without considering the mutual reflection between the admixtures, it may lead to chemical reactions between the admixtures. This is not favourable to the improvement of concrete properties.

Concrete is the main material used in construction. Ensure its performance meets the building requirements. The use of external admixtures must be strictly controlled. The structural stability of the building is improved by optimising the properties of concrete. This makes concrete admixtures play an important role in the construction industry. China should strengthen the development of the performance of external admixtures, take the long and make up for the short, so that the admixtures as an important construction supporting technology in the implementation of the project to play due value.
