| Abstract: | The ettringite type expansion agent with different expansion coefficient isprepared by using different variety, pattern and quantity of gypsum containing aluminiumraw materials. The influence regularity of different expansion agent on cement property isstudied. The relation between composition and performance of the expansion agent is analyzed and the expansion agent should be designed as per concrete property requirements. |
