Abstract

Authors made dear that addition of a small amount of Welan gum alters the properties of concrete, e. g. improvements of self-consolidating property in the case of highly fluidized concrete. But the experimentation concerning highly fluidized concrete with Welan gum was done with using limited materials only. In this report, Welan gum's compatibilities with various superplasticizers and powders were estimated experimentally. As a result, it was found that Welan gum provides its functions in highly fluidized concrete without depending on sorts of superplasticizers and powders. And in the case of the system with using only cement i, e, the system without iron-blast-furnace slag powder or fly ash, addition of welan gum increased degree of the change as time-passing regarding the flow-property. On the other hand, in the case of the system with using iron-blast furnace slag powder or fly ash, addition of Welan gum decreased it.
