| Title of the article | The effects of plasticizers on the basic properties of the gypsum cement-pozzolan binder based on low branded gypsum and technogenic raw materials |
| Abstract. | Currently there are a lot of plasticizers, giperplasticizers and superplasticizers of different brands in the domestic market. However, the effectiveness of these supplements declared by the manufacturer primarily for the compositions based on cement. It is known that the alkalinity of the medium has a significant effect on the operation of plasticizing additives in the binder. This makes it necessary to study the work of modern plasticizing additives in the gypsum cement-pozzolan compositions. The studies have established a positive impact of plasticizing additives on the rheological properties of the gypsum cement-pozzolan binder based on low branded gypsum and technogenic raw materials and the physical and mechanical properties of the composite gypsum cement-pozzolan stone. It has been shown that the introduction of plasticizers in the composite binder can improve the performance properties of products based on gypsum cement-pozzolan binders, resulting in increasing the flexural strength of 65,2 %, the compressive strength – by 69,9 % as well as increase water resistance by 39 %. These results are achieved by reducing the water demand of the mixture and the formation of a more dense and homogeneous structure of samples on the basis of gypsum cement-pozzolan binder modified researched plasticizing additives. This will greatly expand the scope of products on the basis of the modified composite binder in the manufacture of a wide range of building products. |
