using a water cement ratio of 0.6 was used as control. in green concrete and green building projects). It is an international flexible, material for design, also well-suited for the aesthetics and engineering demands of, 2010), the results of 7 year research in UK, showed that green concrete - containing, either 30% Pozzolan or 70% Slag - had the best overall quality, performance than Portland cement concrete. Fifteen concrete mixtures were produced in three series with control mixes, The durability of sulfate resisting cement pastes in the presence of fine ground limestone and/or silica fume additions was studied. In 1824 an English inventor, Joseph Aspdin, burned and ground together a mixture of limestone and clay. 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. Concrete produced by volume replacement of crushed granite with PKS performed better than one in which crushed granite was construction like: The new extension of Jeddah sea port, East Jeddah hospital, Makkah Chamber of trade, new Holiday Inn hotel Makkah and few green buildings, in Jeddah that where been designed and supervised by Dr Mohammed, In our project, we focused in one of the green cement types which is local. 7. For each eight-minute cement factories dump another 30,000 tons of carbon into the, atmosphere. Superplasticizer SP1 constitutes an incompatibility case when it is mixed with cement containing high C3A or alkali content such as C2 cement. The results show that. <>/MediaBox[ 0 0 595 842]/Parent 2 0 R /Resources 7 0 R /Type/Page>>
The percentage of pozzolanic material used in the preparation should be between 10 to 30. Maximum pozzolan amount with the optimum efficiency was determined.

. cement pozzolana mortars. (Green building code require the using of 30-40% of local pozzolan. The process of âmaking green cementâ is replacing 30-70% of, factories in in the world that produce different types of green cement, each type, provides different alternatives and methods that all lead in one way or another to the, main purpose which is reducing CO2.
