摘要：

This paper studies properties of concrete under the action of water-reducing retarder and expansive agent; gives the optimal design calculation method of cooling water pipe in the construction technology: mainly considering pipe's diameter, distance, cooling water's flow, temperature, time etc; studies the optimization to the concretes construction method. Midas/Civil, one finite element analysis soft-ware, analyses mass concrete construction of the whole process of the temperature field and stress field in the numerical simulation, considering the admixtures and construction technology. The results show that commonuse of admixtures and reasonable construction technology are the important means of controlling cracks.
