Mohamed et al [2] reported that the use of CTW and CSW as sand replacement resulted in low density FSC that is 1220 and 1222 kg/m 3 respectively. This is due to low density of ceramic wastes compared to natural fine aggregate and also increment in porosity induced by ceramic wastes.
In addition to health and safety concerns, sandblasting can also be damaging to surfaces and requires a lot of preparation. The sand can break up into small particles that can be harmful if inhaled. Due to these risks, many countries have prohibited the use of sandblasting, and alternative blasting tools are now commonly used.
