Long-range building materials with possible complex of desired properties are silicate-natric adhesive-based composites. One of effective ways to increase silicate-natric composites water resistance is using of modifying compounds containing polyad metals ions (Zn2+,Ca2+,Mg2+,Al3+). This paper presents some patterns of silicate-natric composites structuring with ethanoate zinc as a water solution. There are results of X-ray phase analysis of silicate-natric composites sample. X-ray phase analysis (XPA) was held with diffractometer проводился на дифрактометре DXGP-4 using X-ray tube with anode copper (Сu-K излучение). For analyzing XRD patterns date base PCPDFWIN, v. 2.02, 1999, (JCPDS) was used. It is clear that as a result of sodium silicate and ethanoate zinc water solutions interaction in optimal range zinc salt is fully under alkaline hydrolysis. It is also highly likely that this interaction produces supplementary compounding sodium acetate, at the initial stage, and various forms of zinc orthosilicate and hydrooxyde, characterized as insoluble and low-soluble compounds respectively, that promotes water resistance increasing of studied composites, when low-baked (110°С). In terms of researches compounds of various profiles are developed and recommended (heat-isolating, heat-isolating-constructive, constructive) with high functional and operating characteristics).
