ABSTRACT
Due to increased urbanization and population with corresponding growth in the economy, the construction industry is expanding rapidly. The expansion of the construction industry has increased the consumption of concrete and its constituents especially Ordinary Portland Cement (OPC). The increased consumption and production of OPC is increasing environmental pollution due to the exponential increase in greenhouse gas emissions (like carbon dioxide). In view of this, addition of supplementary cementitious materials (like fly ash, silica fume, and slag) as cement replacement is encouraging to reduce the overall detrimental impact on the environment and promote sustainability in the construction industry. In this research, cenosphere (CS) and fly ash (FA) were incorporated as cement replacement from 0% to 20% with an interval of 5% to prepare high-performance mortar. The effect of CS and FA incorporated high-performance mortar was evaluated for rheological, mechanical, and durability properties cured under different conditions (water and dry) and temperatures (20 0C and 80 0C). These properties include workability, packing density, water absorption, compressive strength, flexural strength, fire resistance, acid attack, and drying shrinkage. The results revealed that water curing at a higher temperature is more effective than other curing condition and temperatures. It was also indicated that the incorporation of CS enhanced properties like flexural strength, fire resistance, acid attack, and water absorption. Furthermore, 10% replacement of cement with CS and FA proved to be the most effective against the mentioned properties.
