PORTLAND CEMENT Chemical composition. Portland Cement is made up of four main compounds: tricalcium silicate (3CaOSiO2)‚ dicalcium silicate (2CaOSiO2)‚ tricalcium aluminate (3CaOAl2O3)‚ and a tetra-calcium aluminoferrite (4CaO Al2O3Fe2O3). In an abbreviated notation differing from the normal atomic symbols‚ these compounds are designated as C3S‚ C2S‚ C3A‚ and C4AF‚ where C stands for calcium oxide (lime)‚ S for silica‚ A for alumina‚ and F for iron oxide. Small amounts of uncombined

laid lime plaster. Water is used as the vehicle for the pigment and‚ with the setting of the plaster the painting becomes an integral part of the wall. Fresco may thus be contrasted with secco mural painting techniques‚ on plasters of lime‚ earth‚ or gypsum‚ or applied to supplement painting in fresco. The fresco technique has been employed since antiquity and is closely associated with Italian Renaissance painting. Buon fresco technique consists of painting in pigment mixed with water on a thin layer

Committee had been approved by the Civil Engineering Division Council. Portland slag cement is obtained by mixing‚ Portland cement clinker‚ gypsum and granulated slag in suitable proportions and grinding the mixture to get a thorough and intimate mix between the constituents. It may also be manufactured by separately grinding Portland cement clinker‚ gypsum and granulated slag and then mixing them intimately.. The resultant product is a cement which has physical properties similar to those of ordinary

titled Ashurbanipal hunting Lions and belonged to the North Palace of Ashurbanipal. It was created in 645 to 640 BCE and like many reliefs; it pictured a hunt taking place. It was average sized at about five and a half feet tall and carved out of Gypsum rock giving itself a red hue. This falls into place with the description of most reliefs from this time. But what made this Assyrian relief stand out? It was a small detail‚ a lioness to be exact. The hunt depicted did not take place in the wild
