Implementation of Unprocessed Dried Horse Manure Ash in Sustainable Concrete


Objectives: To examine the strength characteristics of the given grade of concrete after partial replacement of the cement (5%, 10%, 15% and 20%) as well as partial replacement of the sand (5%, 10%, 15% and 20%) by Horse Manure Ash (HMA). Methods/Statistical Analysis: Implementation of HMA as an admixture, in the direction of producing high strength concrete is a novel approach. This paper presents change in the properties and in the behavior of concrete, with and without using HMA. In and all 72 specimens with proposed M30 grade mix were casted and tested. Slump tests and compaction factor tests were used to determine the workability of the green concrete. The compressive strength of cube blocks was obtained at 7 and 28 days and the flexural strength of prism blocks was obtained at 28 days for the determination of strength characteristics. Findings: In most of the previous research works authors have made attempts to incorporate several supplements for the cement and aggregates like that of fly ash, clay, slag etc. and natural as well as synthetic fibres like that of the fibres obtained from steel, glass, metals, coir, jute, plastic, rice husk, straw etc. into the concrete. Dried horse manure and its ash produced after burning was never used for research purpose. The experiments performed for the present research work have shown that the addition of HMA as an admixture in concrete mix showed encouraging and interesting results when tested at 28 days. The best possible replacement of HMA in concrete without affecting target mean strength was found to be up to 10% for cement replacement and 15% for sand replacement. The workability of the designed concrete mix increases continuously up to the 20% replacement of sand as well as of cement by HMA. The maximum compressive strength and flexural strength at 28 days of concrete was found when cement is replaced up to 5% and sand is replaced up to 10% by HMA in concrete mix. Application/Improvements: Horse manure is a natural organic waste obtained in huge amount from the defence areas and other sports campuses. This waste can be successfully utilized for the production of high strength concrete.
