		abstract={At this time the use of concrete-making materials that is used continuously will be depleted, therefore a material that can replace the main material for making concrete is needed. These substitute materials include residual waste in the community, especially ceramic waste, shellfish, and rice husk ash. This
research has been done by many other people to examine the use as a substitute for concrete, therefore the researchers conducted this research to calculate the production cost or manufacture of concrete with these substitutes which will be compared with the PUPR Regulation.}
