STUDY ON NEEM SEED HUSK ASH AS REPLACEMENT MATERIAL FOR CEMENT
Partial replacements of constituents of concrete have been the recent developments in the field of Civil Engineering and materials research. Neem Seed Husk Ash is partially replaced with the cementing material and the strength criteria are monitored and compared with the conventional ones to prove the effectiveness of the utilization of the replacement material. The properties of the M30 grade of concrete partially replaced with Neem Seed Husk Ash (NSHA) are studied experimentally, and the variations in strength are monitored. The compressive strength of the NSHA concrete increased with age but decreases with the increase in the proportion in the ash to cement. The setting time and workability of the NSHA concrete decreased as the replacement level of the Neem seed husk ash to cement increased with the different percentage of NSHA and combination of NSHA with suitable proportions of superplasticizers. Even though NSHA in concrete shows an increase in strength in the previous studies, and the results obtained from the NSHA concrete in this experimental investigation indicated a reduced compressive strength.
