- W3214761766 abstract "AbstractCement industry is one of the major sources for global warming due to large amount of emission of carbon-dioxide. It is really important to reduce the usage of cement and replace cement with other industrial by products, which are produced in tons and used as landfill. Cenosphere is one promising waste material generated from coal power plants along with fly ash that can be used as partial replacement for cementious material. This work focuses on the usage of lightweight cementious material, i.e. cenosphere as a partial replacement for Ordinary Portland Cement (OPC). Cement properties such as initial setting time and consistency were measured. Compressive strength was studied using mortar cube of size 70.7 × 70.7 × 70.7 mm. Water absorption and sorptivity characteristics were measured using cylinder specimens of size 100 mm × 50 mm. Cenosphere was replaced at an amount of 5–20% of cement weight. Five different mortar mixes were prepared with 0 (control), 5, 10, 15 and 20% of weight of cement replaced with cenosphere. From the study, it was observed that the initial setting time and consistency increases with the increase in percentage of cenosphere. The measured consistency for 20% replacement of cenosphere was about 35%. The initial setting time increased from 40 min (OPC) to 147 min for the replacement of 20% of cement. There was only a slight reduction in the crushing strength with the cenosphere replacement. From the experimental work, it can be stated that effect of cement replacement with cenosphere has only a small impact on the consistency and strength. Cenosphere being a hollow lightweight particle, when added to cement reduces the density of cement products, reduces the cost and also the environmental impact. It also improves the durability, workability and shrinkage resistance of cementious mix." @default.
