摘要

In order to find out the long-term deformation behavior of MgO concrete, the nearly 10 years prototype observation data of Dongfeng arch dam foundation is analyzed. The results show that the MgO concrete has excellent delayed micro-expansion character, and its long-term expansive deformation always tends to stable level without any trend to contraction or infinite expansion, and by adding appropriate MgO expanding agent which was calcined at some high temperature into concrete, the cracking resistance of the concrete is improved. It is an effective way to construct dams excellently, efficiently and economically by using MgO concrete technology.
