1. Introduction

Existing studies mostly use quartz sand and river sand to prepare RPC; the use of manufactured sand to prepare RPC is still in its infancy [3]. Using manufactured sand instead of quartz sand can lower the cost. And if the river sand could be replaced by the manufactured sand, the damage to the river bed and dam could be lessened.
