Abstract
In this article, the optimal conditions for the synthesis of superplasticizer based on UzKor Gas waste naphtha raw material (with 85-90% naphthalene) are studied. It was determined that the optimal temperature is between 60-700C and 130C0, and such substances as formalin, sulfuric acid and sodium hydroxide were used. According to the obtained results, this super plasticizer was dissolved in 42 g of water and mixed with 100 g of cement, and its expansion was tested based on GOST 310.3-76.
