A Study of property compressive strength and bending strength of concrete mixed with ceramic fragments

Abstract

This research aimed to study the compressive strength and flexural strength of concrete mixed with fragments of ceramic ware factory in Phayao by replacing fine aggregate and coarse aggregate with ceramic fragments in a ratio of 2.5, 5, and 5 percent, respectively, compared with 10 control samples, concrete, ceramic fragments that were not mixed. This study tested the compressive strength at 3, 7, 28 and 56 days and flexural strength testing. The mixed concrete was designed as the 210, 240, 280 ksc. The study found that the ceramic fragments mixed in the concrete compressive strength were increased. At the same time, adding more sand instead of ceramic chip decreased the compressive strength. The optimum ratio that producted a maximum compressive strength was ceramic fragments instead of 2.5 percent of sand,and instead 10 percent of rock, which had more compressive strength than controlled concrete, representing 103 percent. The average flexural strength of concrete beams mixed with, ceramic fragments was 113.15 percent more than the concrete examples of concrete mix design control ratio.
