properties. Concrete additives, such as fly ash and blast furnace slag, are used for this purpose [3–5]. Fly ash (FA) is a by-product of the coal dust combustion process in heat plants and power plants, and after passing the certification process, it can be used as an additive to concrete. The use of FA and blast furnace slag as an additive to cement and concrete mixtures allows for waste

Admixtures and additives for concrete PCC Group

The dynamic development of the construction industry stimulates the emergence of increasingly modern additives and admixtures for concrete on the market. They represent a wide range of products with various chemical structure and properties. These substances are added in small amounts to concrete mixtures and interact with its components, ensuring the desired effect. As a result, the modified

Therefore, chemical additives are used to delay thickening, while still allowing the cement to set within a reasonable time to allow resumption of operations. The cost of premature setting can be as high as the redrilling or abandonment of wells. On the other hand, the costs of an overdelayed cement set can be poor cement quality because of invasion by formation fluids, casing poor cement
