Strength, sorption and abrasion characteristics of concrete using ferrochrome ash (FCA) and lime as partial replacement of cement
چکیده انگلیسی
This paper presents the results of experimental investigations and microstructure study carried out to evaluate the possibility of utilization of ferrochrome ash (FCA), a waste product from ferroalloys industries for partial replacement of cement in concrete preparation. FCA is used in four different substitution rates such as 10, 20, 30 and 40% along with 7% lime. Various strength and durability tests were conducted to understand the effects of FCA and lime on performance of concrete. Test results revealed that replacement of cement by FCA in various % with 7% lime enhanced the 28 days compressive strength 1.5-13.5%, flexural strength 4.5-9%, bond strength 15-29%, abrasion resistance 10-23% and reduced the sorptivity 25-43%. The concrete containing 40% FCA and 7% lime, replacing 47% of ordinary Portland cement (OPC) in total, exhibited strength of normal concrete or even more at all ages. XRD and petrography studies confirmed the results of mechanical and durability properties.
