Fig2 Effect of Fly Ash on Concrete Permeability Effect of fly ash on carbonation of concrete Carbonation is a process in which carbon dioxide in air reacts with calcium hydroxide and sometimes calcium silicates and aluminates in hydrates cement and produce calcium carbonate.
Compared with USB with 15 cement alone the use of 1 lime together with 9 fly ash as the admixture of 15 cement was recommended for preparing USB which can increase 7 28 and 60day compressive strength by 87 56 and 44 respectively On this basis addition of NS to USB can further improve its compressive strength.
This standard was first published in 1966 in three parts to cater to the requirements of fly ash for three specific uses Part 1 covering use of fly ash as a pozzolana Part 2 covering use of fly ash as an admixture for concrete and Part 3 covering use of fly ash as fine aggregate for mortar and concrete The Sectional Committee responsible.
