IMPROVING THE PROPERTIES OF MOBILE SANDS WITH MODIFIED CONNECTORS BASED ON LOCAL RAW MATERIALS

The article examines the possibilities of obtaining a solid-reagent for the production of a polymer-binding additive" SXM-1", obtained on the basis of the waste of the process of production of GIPAN" Navoiyazot "AJ and" Maksam-Ammofos " AJ waste phosphogips, and the possibility of obtaining these reagents as a result of studying the possibilities of obtaining a solid-reagent, the effect of the granulometric and mineralogical composition of the polymer "SXM-1" in the composition of the sand on the hardening of the sand protective layer was determined based on the study of the laws of moisture change and absorption process on the sand surface of various binders On the surface of wet and dry sand, an improvement in the properties of wind and frost resistance was determined based on the formation of a protective layer by means of a polymer solution "SXM-1" and an improvement in the processes of its absorption, moisture retention.
