Research on the Preparation of Economical Powder Concrete-UHPC

Abstract:

In this paper I will introduce a new kind of powder concrete which I call it UHPC.UHPC is a kind of high performance concrete. Now the cost and the condition of ordinary powder concrete is too high. It is unfavorable to the popularization and application of powder concrete. This article mainly is to use gravel that have particle size range between 3 ~ 5 mm and particle size range between 1 ~ 3 mm and particle size range between 0.21 ~ 0.42 mm river sand .the aggregate will through the close packing to match. Gelling materials mainly use three kinds of cement. They are ordinary Portland cement 52.5, sulfur-aluminum cement, and superfine cement grinding. The appropriate ratio of gelled material will determine by the experiment. Poly carboxylic acid additive and defoaming agent will be used to configure the reactive powder concrete. Main purpose is to configure economy powder concrete in Regular maintenance condition.
