| Abstract: | In order to raise \{anti cracking\} ability of concrete of face slab, a mass of laboratory experiments and \{in situ\} implementations have been carried out. And to add composite admixture of three agents, \{water reducing\} agent, \{air entraining\} agent and \{micro expansion\} agent, into the concrete of face slab; has been proposed and carried out. Meanwhile, taking \{anti cracking\} coefficient to evaluate the anti-cracking ability of concrete of face slab, is proposed too. The practical applications show that it has good effectiveness. |
