Analysis of the Characteristic behaviour of Concrete with Rice Husk Ash and Sugarcane Bagasse Ash
In the last decades, the use of residue in construction industry, especially as additives in concrete, has been subject of many researches as it may lead several improvements in the concrete properties, besides reducing the environmental pollution. The world rice harvest is estimated in 600 million tons per year. In terms of production sugarcane tops the crop ranking order. In India alone there grows 352 million tons of sugarcane and processed by 138 sugar mills. Considering that 22 of the grain is husk. So both the rice husk and sugarcane bagasse ash are complete waste and can be used as substitutes in concrete. The RHA and Sugarcane bagasse ash were trialed to replace concrete with various ratios of RHA 0 , 10 , 20 , 30 and 40 with fine aggregates and SCBA 0 , 5 , 10 , 15 and 20 with cement. The water cement ratio in all the mixes was maintained at 0.55. From the experimentations it was inferred the modified specimen resulted in number of improvement of properties of cement. The observed increase in compressive strength of concrete is maximum, when the conventional concrete is modified with 15 SCBA and 30 RHA. With this percentage modification there seen increase in both 28 as well as 7 days compressive strength. There observed considerable reduction in slump value yet keeping the mix workable or in other words we can say that modification of concrete by SCBA and RHA do not adversely affect the workability. The 28 day split tensile strength test revealed that the inferences of compressive strength test and split tensile strength were somehow similar to one another. More the application of SCBA and RHA, lesser are their disposal problems and thus results in reduction of carbon credits by these waste products. This research promoted an ecological way of waste management and sustainable construction.
