  • Performance of crystalline forming additive materials

    Currently, crystalline forming additive materials (CA) are widely used to reduce concrete permeability (ACI 212) It has been postulated by many researches [3] , [4] , [5] , [6] , [7] and even with the materials manufactures that these materials have the ability to seal the concrete surface by filling the concrete cracks and large pores with insoluble crystalline materialsAdditive materials from waste affect concrete’s mechanical properties and thus can contribute to useful waste disposal Sorel cementbased materials with new additions have become theAdditives in Sorel Cement Based Materials Impact StudyThis paper studies the influence of different additives (fly ash, silica fume, and metakaolin) to the concrete mixture with different ratios of (0, 5, 10, 15, 20, 25, 30%) by weight of cement, with(PDF) Experimental Comparative Study of Effect of
