STUDY TOWARDS UTILIZATION OF CONCRETE USED SCALLOP SHELL AS FINE AGGREGATE

Abstract

 We aimed at the establishment as a large quantity of recycling methods of a shell holding and carried out various research works for use of the scallop shell to concrete. Because it was difficult to crush it into the appopriate size that could apply a scallop shell as fine aggregate, we took up a rotary crushing machine with the results as the shell crusher and examined the crush performance. And, about shell concrete that uses scallop shell as fine aggregate, we carried out various indoor examinations to grasp basic properties and field proof examinations aiming at verification of the problem towards utilization. From the results of indoor experiments and field examinations, the basic property and utility of the shell concrete are confirmed. Shell sand concrete has almost same properties in comparison with the normal concrete.
