Title of the articleВlended сements with сomplex mineral additive for mortars with improved physical and mechanical properties for a modern building
Abstract.Modern building industry makes to building materials special properties of strength, density, water resistance, weather resistance, corrosion resistance. Mortars also are not exception. Blended Portland cements with complex mineral and organic additives solve not only environmental issue, resource and energy saving, but allow to get a cheaper product, through the use of regions mineral resources. Furthermore, using of hybrid complex mineral additives allows to obtain products, construction materials with a special properties. According to our earlier studies the blended cement with complex mineral additives based on metakaolin, fly ash and Tripoli, allows to save up to 30 % of the Portland cement (PC) without decreasing compromising strength. The paper shows the investigation of physical and mechanical properties of the mortars based on the composite Portland cement with the complex mineral additive. The experimental results have allowed the possibility of replacement of Portland cement up to 50 % in the composition by the complex mineral additive for mortars without strength loss. The content of additives in an amount of 10-30% can improve the physical and mechanical properties at 30 % and 10 %, respectively. The physical chemical properties, such as compressive and tensile strength, freeze-throw resistance, water improving of mortars based on the blended cements with complex mineral additives were investigated.
Keywords.blended Portland cement, complex mineral additives, mortar.
