DEVELOPMENT ON REINFORCED MORTAR BY FLY ASH FIBER AND APPLICATION TO OUTER-SHELL PRECAST CONCRETE MEMBERS : Studies on utilization of coal ash for coment products

Abstract

This report describes test results on the mechanical properties of fly ash fiber reinforced mortar, and application of permanent precast forms to concrete members. As the test results, it was confirmed that the fly ash fiber reinforced mortar maintained excellent workability, high flexural strength and thermal resistance. Therefore, as the fly ash reinforced mortar precast form is thin and light, treatment in the site of construction is very easy. And the results of measurement of the strain at surfaces of the precast form, the fly ash fiber reinforced precast form possesses the full safety for lateral pressure due to ready mixed concrete.
