Effect on Concrete Strength by Partial Replacement of Cement with Cotton Stalk Ash and Rice Husk Ash

Huge quantity of Cotton stalk ash and rice husk ash are generating as a waste product in agriculture sector in India and many other developing countries every year. In lack of proper wakefulness and technology expansion, great portion of these by products remain unutilized causing severe disposal and environmental troubles. The main goal of this thesis is to examine the performance of M40 grade concrete with a mix ratio as per M40 grade and a water cement ratio of 0.425 Additionally, it aims to determine the compressive strength, flexural strength, and split tensile strength of concrete cement when cotton stalk ash and rice husk ash are used in place of cement. With various percentage like 10, 20, and 30 etc. of cotton stalk ash and rice husk ash well as with combined replacement of Cotton stalk ash and rice husk ash. and results that the workability of concrete was found to be reduced on enhance the Cotton stalk ash CSA , rice husk ash RHA by difference percentages. The Maximum increase in 53.67 N mm2 of compressive strength is obtained after the period 28 days with cotton stalk ash substituting 10 of the cement CSA . The maximum increase in flexural strength over the period of 28 days was 5.98 N mm2, with cotton stalk ash substituting 10 of the cement CSA . When 10 of the cement is replaced with cotton stalk ash, the significant increase in split tensile strength for 28 days is 4.23N mm2 CSA By substituting cotton stalk ash, rice husk ash for 20, 10 of the cement, the compressive strength as per this investigations for 28 days is observed 49.47 N mm2 CSA, RHA is not achieved highest value but achieve the target mean strength. The greatest results are achieved when cotton stalk ash are utilized, although at different percentages.
