Based on the technical performance requirements of the concrete for Chengdu Shuangliu International Airport terminal 2 , C40“designed concrete”was prepared,the effects of expansion agent (HCSA) and pottery sand on shrinkage property and mechanical property of the concrete were studied,and the production guidance mix was determined. The 28 d,180 d shrinkage ratio and static elastic modulus of the concrete respectively were 43×10-6,215×10-6,and 3.02×104 MPa.And its crack resistance reached L-V level,all the perfor-mance of the concrete perfectly met the requirements of the engineering design.
