This article studies the effect of the newly produced PKN 30% chemical additive on the water-cement ratio of concrete based on local raw materials. The difference in the dosage of the additive and, through it, the cement-water consumption, compressive strength, and long-term durability are a number of factors that influence it. When using PKN30% chemical additive in different proportions, water demand is significantly reduced, it covers the surface of cement particles, and high mobility is achieved with less water. PKN30% chemical additive is used as a plasticizer that reduces the water-cement ratio, is energy-efficient, and has high strength indicators.The purpose of using the PKN30% chemical admixture is to consider different ratios of water-cement parameters of concrete and select the optimal option.

This article discusses the effect of PKN30% chemical additive on concrete strength, its application technology, and practical significance.
