Study of Urban Atmosphere Harmful Substances Adsorption into Cement

AbstractThe ecological safety issues of building materials are the most important area nowadays. The impact of different substances and materials on human organism is the major point for emission control of building industry enterprises. One of the main factors can be building dust that could be presented as cement. For that purpose the qualitative and quantitative composition of samples and its adsorption capacity should be known. The article presents a comparative analysis of dust and cement. Quantitative characteristics of adsorption activity of different branded cements (CEM-I 42.5N, CEM-II/A-SH 42.5N, PC 500-D0-N) are shown. The impact of atmosphere humidity on static adsorption capacity of selected samples at specified temperature was estimated
