Impact of Ferrochrome Ash and Gypsum Powder on

2019-7-1 · Acharya and Patro (2016) reported that there was enhancement of 28 days compressive strength (1.5-13.5%), flexural strength (4.5-9%), bond strength (15-29%), abrasion resistance (10-23%) and reduction of sorptivity (25-43%) due to substitution of cement with ferrochrome ash FA in various percentage with 7% lime substitution. The concrete having 40% ferrochrome ash FA and 7% lime showed same amount or even more strength than normal concrete mix at all ages. Due to incorporation of ferrochrome ash FA and lime caused decrease in workability and slight increase in fresh density. Replacement of ferrochrome ash with lime has a positive impact in compressive strength whereas, only replacement of ferrochrome ash FA with cement may cause a negative impact in concrete. There was a positive impact on abrasion resistance of concrete with incorporation of ferrochrome ash FA and lime. Concrete in which ferrochrome ash FA and lime are incorporated found less sorptivity than normal concrete mix. It was reported that ferrochrome ash
