| Abstract: | The reasons of cracking of large mass concrete construction in the early age are analysed and the technical thinking and ways of prevention of cracking are presented in this paper.UEA micro_expanding agent was used in the construction of the World Trade Centre of chongqing.The early contraction of corcrete is changed into limited expansion.the practical engineering experience is obtained in efficiently perventing the early cracking of concrete and ensuring the strength of concrete. |
