    d) 5070 . Answer a. Explanation The removal of excess air after placing concrete helps in increasing the strength of concrete by 1520 . To attain these positive effects the typical individual limitation for OPC replacement is commonly estimated to be 15–20 for FA and 40–50 for GGBS.

    Process integration study of tailend CaLooping process

     · In this work the integration of Calcium looping (CaL) process into a cement plant for postcombustion CO 2 capture is assessed via process simulations. In the proposed scheme the carbonator of the CaL process is used as an endofpipe unit to capture the CO 2 from the cement kiln gas.. From the results obtained it is demonstrated that CO 2 capture efficiencies of the order of 90 are

    General The quality of alternative fuels differ significantly depending on type origin and preparation. When using AF with high heat value small particle size and low Chlorine we could reach 100 AF rate in most of our kilns but high quality AF are becoming increasing more difficult to source or have a fuel cost similar to fossil fuels.

    Blending of mining wastes from the Hammam Zriba mine

     · Results show that it is possible to use these wastes to formulate an ecological clinker with high quality. The reference clinker is composed of C3S ( ) C2S ( βC2S and αC2S) and C3A ( ) associated with small quantities of C4AF. The incorporation of 2 of wastes does not lead to any significant change in mineral composition.

    Tricalcium Silicate (C3S) C3S is the most abundant mineral in Portland cement occupying 40–70 wt of the cement and it is also the most important. The hydration of C 3S gives cement paste most of its strength particularly at early times. Dicalcium Silicate (C2S) As with C3S C2S can form with a variety of different structures.

    SYNTHETIC POZZOLANSSolidia Technologies Inc.

    Synthetic pozzolans are produced using local materials to provide a cementitious material that is uniform in chemistry and properties independent of the location where the materials are obtained. Two methods of production are described. One is a high temperature process in which materials are processed in a semimolten or molten state.
