The demand for cementitious materials has increased due to industrialization and urbanization, leading to environmental concerns. The use of industrial waste, like cenospheres, as construction materials offers economic and practical advantages. Recent studies have shown that cenospheres can be used as lightweight materials for structural cementitious materials. This article discusses the properties of cenospheres and their impact on the construction sector. The study concludes that incorporating cenospheres into cementitious materials leads to significant improvements in various aspects and can replace cement and fine aggregates without major detrimental effects on engineering properties.
The increased demand for cementitious materials due to rapid industrialization and urbanization has raised several environmental concerns. To construct environmentally sustainable infrastructure, the possibility of using industrial waste (like cenospheres) as construction materials is highly desirable with various economical and practical advantages. Recent studies revealed the practicality of using cenospheres as lightweight material to prepare structural lightweight cementitious materials. Therefore, this article discusses the properties of cenospheres related to the construction sector. Moreover, the effect of cenospheres on the engineering properties (i.e., physical, rheological, mechanical, durability properties), and sustainable benefits of cenosphere modified cementitious materials are comprehensively documented. The article concludes that cenosphereincorporated cementitious materials can attain significant improvement in the domain of lower density, rheological properties, thermal conductivity, acoustic insulation, and sustainability development, etc. It can also be concluded that cenosphere can replace approximately 10% and 30% of cement and fine aggregates, respectively without causing any significant detrimental impact on the engineering properties of cementitious composites.
