| Title of the article | Influence of siliceous on phase composition of the hydrated cement with a polyfunctional additive |
| Abstract. | Improvement the efficiency of the use of concrete in the manufacturing of building products and structures concerned with the use of various types of modifiers. For modifying the construction materials the nano-additive of various kinds are used increasingly and efficiently enough. Specificity of nanotechnology is the difficulty in the base material statistically uniform distribution of the control dose «primary» nanoparticles which are also prone to aggregation. Particular interest for the modification of cement concrete are nanopowders (graphite tube, aerosol etc.) And sols (siliceous, alumina) which are expedient to use as a component for the production of polyfunctional additives. In this regard, the aim of the work was to study the siliceous nano-additive together with concrete modifier effectiveness. The article shows the influence of siliceous sol with superplasticizer on cement paste strength. The results of the study of the polyfunctional additives using siliceous on the structure cement system, and on physical and mechanical properties of heavy concrete are shown and thermographs of cement hydration products with their using are performed. The result of the tests is shown opportunity of using siliceous sol as a component of the complex concrete additives for performance enhancing. |
