EFFECT OF VALUE ADDED ADMIXTURE ZEOLITE ON SETTING TIME AND COMPRESSIVE STRENGTH OF MAGNESIA CEMENTR.N. Yadav and RamkishanAbstract In 1867,S. T. Sorel discovered Magnesia Cement in an aqueous solution by reacting magnesium chloride with magnesia. In comparison to Portland cement, this has versatile cementing characteristics. As an inert filler to absorb the heat evolved during the exothermic formations of magnesia cement Dolomite is used. Authors in this research paper have prepared Dry-mixes composition of magnesia and dolomite (inert filler) in the ratios of (1s And then these are gauged with 24oBegauging -solutions MgCl2 and the impact of admixture on their setting time -initial and final and compressive strength can be found. The initial and final setting time was observed to be increasing remarkably. With increase in percentage of admixture (zeolite) time of the cement blocks increased in the initial and final setting time also ratio of inert filler (dolomite) in the each dry-mix composition was observed and recorded. In the results it was found that to the percentage composition of admixture (zeolite) both initial and final setting time of cement blocks and also the ratio of inert filler in the dry-mix composition itis directly proportional. Quantity of magnesia cement drastically increases with Incorporation of zeolite and this further remarkably increases and improves strength of the cement. Magnesia cement could in fact act as carbon sinks, acting to favorably reduce greenhouse gas emissions. It is eco friendly cement. |
