Abstract
In Iran, the increase in migration in the cities and the increase in the construction of buildings has caused a lot of extraction of natural stone mines for the production of concrete. Also, repairing or demolishing dilapidated buildings increases the production of waste and construction waste, especially in big cities. Unfortunately, a large amount of these construction wastes are transferred to the surroundings of the cities as waste and buried. These two causes cause the sustainability of the environment to face a serious risk. The use of recyclable materials and their reuse in the construction of new materials has many advantages, which include economic savings, reducing the amount of waste and preserving natural resources such as stone mines. In this research, with the aim of recycling and reusing construction waste, ceramic waste in different volume ratios of 25%, 50%, 75% and 100% was used instead of natural sand in self-compacting concrete. Also, in order to increase the quality of rheology and consistency of SCC concrete, zeolite powder was used instead of stone powder. The tests performed include slump flow, V funnel, L box, compressive strength at different ages, concrete durability check against freezing, and concrete failure SEM check. The results of this research showed that adding up to 25% of ceramic waste in concrete reduces the 28-day compressive strength by less than 10%. Also, the amount of weight loss and resistance of this design after exposure to 300 cycles of melting and freezing were measured as 3.2% and 5.9%, respectively.
