| Title of the article | Influence of a complex modifying additive on the composition, structure and properties of artificial stone on the basis of composite gypsum binder |
| Abstract. | The influence of the hybrid mineral supplements on the composition, structure and main physical and mechanical properties of artificial stone based on composite gypsum binder, which includes technogenic products – 20 % haydite dust and 30 % granulated domain slags by weight of the gypsum binder. The introduction of this mineral supplement together with lime and superplasticizer making denser the fine-graned structure of artificial stone compared to binder without additives. Occurrence of low-basic calcium silicate hydrates, that filling pore space, sealing the stone structure, create additional contacts in the main matrix and protecting gypsum crystals splices from dissolution is observed. Established that the proportion of closed pores in the pore structure of the stone based on composite gypsum binder is increases. Compressive strength of artificial stone based on composite gypsum binder, modified by hybrid mineral supplements and curing 28 days under normal conditions achieved 30,5 MPa, softening coefficient – 0,92. |
