In this research, The Effect of Chemicals Ratio on Physical Properties of Dope TC and Tread Splice Cement were studied. In the experimental, the ratio of chemicals in Cement were varied by increase and decrease from standard chemicals value in Cement about 5%. Then, the physical properties such as viscosity and total solid content were tested from initial to 7 day (Storage). Finally, we found that the PGX-2 affect to the viscosity of Dope TC. The ratio of chemicals in Cement, we found that a little affect to the total solid content of Dope TC. And, we found that PGXX-1 PGXX-2 and PGXX-4 affect to the viscosity of Tread Splice Cement. The ratio of chemicals in Cement, we found that PGXX-4 a most affect to the total solid content of Dope TC. For the storage duration of Dope TC and Tread Splice Cement, we found that the viscosity has reduced over the time
