All samples were cured up to 28 days in a sealed container under ambient condition. Only the balance between CAC and phosphate was changed to study the compositional effects. In order to keep the weight % of CsNO constant in the prepared samples, the total weight of the matrix forming reagents (CAC and phosphate) were kept constant, as well as that of water. The CAP samples were prepared by mixing calcium aluminate cement (CAC) with the aqueous solution of sodium polyphosphate and CsNO. The present study investigates the compositional effects on the CAP system, focusing on the effects of phosphate on the incorporation of CsNO. Cs is one of the key radioactive nuclides which causes the majority of the radioactivity in the earlier age of nuclear wastes, yet difficult to incorporate into cement systems due to the mobile nature of an alkaline element. Our previous study indicated a potential advantage in phosphate modification of this system for incorporation of CsNO. We have chemicals for Rust preventives, laundry chemical, housekeeping chemicals etc. Irisawa, Keita Mcgahan, M.* Meguro, Yoshihiro Kinoshita, Hajime*Ĭalcium aluminate cement modified with phosphate (CAP) has been studied as one of the alternative cementitious matrices for the encapsulation of nuclear wastes, especially those containing reactive metals.
