  • The use of the cement and increased with the recent development of the construction industry. If the cement is the environmental problems caused by generating a large quantity of CO2 and the production process. Accordingly, this study is the test to determine the sulfuric acid and hydrochloric acid resistance properties of the Light weight matrix product of blast furnace slag-based light. A result, the compression strength of the sulfuric acid and hydrochloric acid immersion showed alower strength than the Plain.

  • The effect of pH and magnesium ion on the hydrolysis of dicyclomine HCl was investigated by comparing the rate constant and activation energy. The hydrolysis of dicyclomine HCl was acid-base catalytic reaction and the most stable range of pH was $3{\sim}5$. The magnesium ion accelerated the hydrolysis of dicyclomine HCl in aqueous solution.
