Effect on Autogenous Volume Deformation of Concrete Mixed with Magnesium Oxide and Polyethylene Fiber
摘要
In order to explore the effect on autogenous volume deformation of concrete mixed with magnesium oxide (MgO) and polyethylene fiber, this paper measured the autogenous volume deformation of concrete different admixtures of magnesium oxide and polypropylene fiber revealing the mechanism of compounding in concrete. The results showed that the compounding of MgO and polypropylene fiber has a significant effect on the autogenous volume deformation of concrete, and the more obvious with the increase of mixing amount. It was revealed from the experimental point of view that the cracking effect of concrete compounded with MgO and polypropylene fiber can be effectively improved, which promote the application of panel rockfill dam.
