DEVELOPMENT OF CASTING CALCIUM CARBONATE CONTAINING FLY ASH

Abstract

In order to clarify fundamental properties of the casting calcium carbonate with 60% fly ash content, the reaction property and the compressive strength are investigated. The result are as follows; 1) The reaction property of the casting varies with different types of fly ash. 2) In the case of using fly ash, which has more amount of CaO, the casting has less the rate of water absorption. 3) Initial compressive strength of the casting is less than 10N/mm2. But the casting acquires the compressive strength more than 40 N/mm2 as the carbonation proceeds.
