Study on the Adaptability of Polycarboxylate Superplasticizer to Cement in Guangdong Area

Abstract

There are many types of cement in Guangdong, each with its own differences, so it is important to study the adaptability of polycarboxylate superplasticizer to cement in Guangdong. The chemical composition and physical properties of the cement were tested, and the influence of cement performance on concrete was explored. The results show that the specific surface area of cement affects the dosage of superplasticizer. The larger the specific surface area, the greater the cement adsorbs the superplasticizer. The smaller the specific surface area difference, the better the superplasticizer adaptability. Meanwhile, the chemical composition of cement will affect the strength of concrete, and the more active components there are, the higher the strength.
