Because GGBS has low embodied CO 2, it allows designing concrete mixes for sustainable construction. The manufacture of GGBS requires less than 20% of the energy and produces less than 10% of the CO 2 emissions compared to Portland Cement production. GGBS is a sustainable alternative for Portland Cement in the production of: ready-mix concrete.
Manufactured Sand (M-Sand): Manufactured sand confirming to Zone – II as per IS: 383-1970 is used. It was tested as per Indian standard specification. Table - 4.4 Detailed Description of Test on Manufactured Sand Physical Properties Manufactured Sand result Specific Gravity 2.5 Fineness modulus 2.75 Water Absorption 0.26%
Aug 31, 2012· The manufactured sand will not have this problem; however, quarry dust is not manufactured sand. The permissible silt content in sand is five to six per cent. The filter sand …
The benefits of using GGBS in cement concrete as a mineral filler 15% gave the better results compared to the other proportions (0%, 5%, 10%).The study indicates the possibility of using GGBS as filler in cement concrete.
