| description | The article is devoted to the issues of obtaining pressed building materials based on dihydrate phosphogypsum. Dihydrate phosphogypsum after mechanical activation in a ball mill acquires the ability to harden in pressed specimens. After activation of dihydrate phosphogypsum in a ball mill and its pressing at a pressure of 30 MPa, the strength of specimens increases by 6...8 times compared to non-activated specimens and reaches 25...30 MPa. There is found the influence of various chemical admixtures on binding properties of activated phosphogypsum and there are shown possibilities of water resistance improvement and increasing of other properties characterizing this material. There is studied an effect of aggregates on the building and technical properties of artificial stone made of phosphogypsum and peculiarities of its structure and change under the influence of different factors. |
