Information × Registration Number 0208U002279, 0105U001335 , R & D reports Title Establishment of physical and chemical bases of creation of energy saving technologies of alkaline Portland cements, whih are high-filled by additives of artificial, natural and man-caused origins popup.stage_title Head Krivenko Pavlo Vasilyovich, Registration Date 24-01-2008 Organization Kiev National University of bildiny and tecture popup.description2 The interrelation of processes of structure formation and properties with composite construction high filled alkaline Portland cements was determined, their basic physico-mechanical and operational properties were investigated. Combinations of alkaline cements with high (60-95 %) filling by active mineral additives were optimized. All developed compositions are more active, than cements in compliance with DSTU B V.2.7-46-96. The best for creation of alkaline clinker cements (5-40% of clinker) are compositions "clinker-granulated blast-furnace slag (or fly ash, or waste slag)-alkaline component". P Binders are characterized by setting time 0-45...1-35 hour.-min and strength in the age of: 2 day - 15-20 МPа, 7 day - 22,0-35,6 МPа, 28 day - 38-55 МPа, 180 day - more, then 60-65 МPа, that allows to relate them to rapid ctments. Physical-chemical bases of technology of production of such cements with the high contents of natural and man-caused additives were developed. The methods of regulation of a storage period till 2-6 months were developed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
