Chemical tests of cement help determine its chemical composition. The cement oxides will be used in the calculation of the key compounds of cement such as the tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium alumino ferrite (C3S, C2S, C3A and C4AF). These chemical compounds influence the physical properties of cement, and eventually influence the performance of the cement in the concrete. CTC chemical laboratory can analyze the loss on ignition, insoluble residue, major oxides (SiO2, Al2O3, Fe2O3 and MgO), and minor oxides (Na2O, K2O, TiO2 and P2O5).
