Abstract
In this study, production of a ceramic composite composed o two binders, magnesium oxy chloride (Sorel cement) and trihydrate magnesium hydrogen phosphate , together with nano silica, by casting method of shaping castables, is considered. In order to characterize the product, X Ray Diffraction and to investigate the microstructure and the distribution of phases, Scanning Electron Microscopy and Energy Dispersive X ray analysis were performed. Results indicated that by increasing trihydrate magnesium hydrogen phosphate toghether with Sorel cement,physical properties such as water dissolution,water absorption and prosity improves and cold crushing strength decrease by adding while nano silica the cold crushing strength increase and the trends of dissolution in water, water absorption and prosity decrease.
