the durability of a cement-based material is mainly dependent on its permeability. modifications of porosity, pore-structure and pore-connectivity could have significant impacts on permeability improvement, which eventually leads to more durable materials. one of the most efficient solutions in this regard is to use permeability reducing admixtures among these admixtures for those In india, portland cement was first manufactured in 1904 near madras, by the south india industrial ltd. but this venture failed. between 1912 and 1913, the indian cement co. ltd was established at porbander and by 1914 this company was able to deliver about 1000 tons of portland cement.portland cement portland cement is made from four basic compounds, tricalcium silicate dicalcium silicate tricalcium aluminate and tetracalcium aluminoferrite the cements used in minnesota are made either from limestone and clay, limestone and shale, or limestone and slag.
