Hydrated Lime. The best results seem to be attained when the proportion of cement to lime is as 1 to 1, although proportions ranging from 1 to up to 1 to 2 have been used. The mortar made from one part Portland cement combined with six parts and and one of lime paste, seems to give the best results.
manufacturers, limestone for cement making should have more than 45 % CaO, 1 to 2 % Fe 2 O 3 as well as Al 2 O 3, less than 8 % free silica, less than 0.6 % combined Na 2 O+K 2 O and less than 0.6 % P 2 O 5. Magnesia content in the limestone should ideally be less than 3 %, although as high as 5 % MgO can be used by the cement industry. Magnesia, sulphur
It has been possible to upgrade the qualities of cement by using high-quality limestone, modern equipment, closer on line control of constituents, maintaining better particle size distribution, finer grinding and better packing. Generally, the use of high-grade cement offers many advantages for making stronger concrete.
