Samples of silica-containing material in the highly dispersed state were obtained from various deposits of the Arkhangelsk region. Calculation of surface activity values is presented and the magnitude of the exothermic heat reaction of hydration (enthalpy of hydration change) and amorphous component of silica-containing component of composite binder are defined. It was shown that the surface activity, heat of hydration, the amount of amorphous phase formed by mechanical dispersion of the raw material for the investigated siliceous rocks-are interrelated values. It is established that values of the surface activity, heat of hydration, the amount of fine systems amorphous phase of the studied rocks are in good agreement. These criteria can be used to determine the quality of raw materials used in the formation of the composite binder. Based on the proposed review of sedimentary rocks deposits it was found out that it is preferable to use the alluvial modern Quaternary sand deposits than the alluvial-marine modern Quaternary sand deposits as highly dispersed component of the composite binder. © SGEM2016.
