The tests were con-ducted in accordance with Indian standards [13-14]. also improve the properties of green concrete in both short and long terms. Endotherms associated with the dehydration of gypsum, monosulphate and ettringite were observed by DSC. There, are 17 cement factories producing 55-60 million tons of cement / year (with total, emission of 70-120* million tons of Co2. If cements contain small amounts of very active pozzolana (silica fume, for example), both early and ultimate strengths may be higher than those of the substituted cement. Portland pozzolana cement. Pozzolana cement is not a new product on the world market. The average C3S content in modern cement is about 45 per cent and that of C2S is about 25 per cent.

The share of blended cement in total cement production has increased from 29 per cent in 1997-98 to 54.5 per cent in 2003-04. This mixture, called portland cement, has remained the dominant cementing agent used in concrete production. In combination with portland cement, Class C fly ash can be used as a cement replacement, ranging from 20-35% of the mass of cementitious material. The physico-mechanical properties of the hardened cement pastes exposed to sea water up to one year were investigated. In green cement manufacturing alternatives, for the clinker is used which does not require any amount of heat and as a result. A review is presented of the papers published during the year 1982 in the field of special hydraulic cements. the filled pozzolanic cement pastes give a better resistance in sea water than those without addition at all immersing times. 1 0 obj 2 0 obj It was, observed that, regardless of the source, the chemical and physical properties of, local natural pozzolan are similar and conform to the requirements of, There are many different projects based in KS.
