ABSTRACT In recent decades, concrete technology has reached the broad-based areas of operations through the implementation of Self Compacting Concrete to increase the concrete performance. Due to high silica content, the pozzolonic characteristic of RHA makes it as a supplementary material for cement. In this paper, Cement was partially replaced with Rice Hush Ash of 5%, 10% 15%, 20%, 30% and 40% influencing the properties of SCC. The aim of this report is to explore the effect of cement replacement by RHA on the fresh and mechanical properties of SCC. In addition, the bucking behaviour of the axial loaded reinforced concrete column was predicted using Artificial Neural Network. Experimental data are collected and 100 experimental data is used for training the ANN model and 20 sets of data is utilized for testing. From the results it is observed that SCC blended with RHA shows the positive relationship between 30% replacement of RHA with an increase in the strength of compression and tensile strength of around 6. The buckling behaviour of the 70% Cement + 30% RHA SCC reinforced column was predicted by ANN- PSO is a precision and efficient model.

ABSTRATO A mudanca contínua na forca e outras propriedades, problemas ambientais, aumento no preco do cimento, avanco da indústria da construção civil faz uso de materiais alternativos como materiais de grau funcional (FGM) que leva a um novo material sobre concreto como concreto funcionalmente classificado (FGC), Neste presente artigo, a investigação tem sido realizada no concreto funcionalmente classificado utilizando lama vermelha e também sobre cinzas.Neste grau M20 de concreto é usado como concreto convencional na zona de compressao e M25 com a substituicao de cimento por lama vermelha e flyash com porcentagem variada (5%, 10% ,15%) respectivamente na zona de tensao.Os resultados indicaram que os 10% da lama vermelha e 10% das cinzas de mosca como o valor ideal para o feixe de concreto e pela curva de deflexao de carga, e evidente que o feixe de concreto funcionalmente classificado tem mais vantagens do que o concreto comum, uma vez que possui mais durabilidade e características de resistencia.A análise do microscopio eletronico de varredura também foi realizada no concreto de grau funcional da lama vermelha e cinzas de moscas de concreto funcionalmente classificado.Indicou claramente os poros presentes nos materiais que tendem a aumentar a forca do concreto.

ABSTRACT The continuous change in the strength and other properties, environmental problems, hike in cement price, advancement of construction industry makes the usage of alternative materials as Functionally graded materials (FGM) which leads to a new materials on concrete as Functionally graded concrete (FGC), In this present paper, investigation has carried out on the functionally graded concrete by using red mud and also fly ash. In this M20 grade of concrete is used as the conventional concrete in compression zone and M25 with the replacement of cement by red mud and flyash with varying percentage (5%, 10% 15%) respectively in the tension zone. The results indicated that the 10% of the red mud and 10% of the fly ash as the optimum value for the concrete beam and by load deflection curve, it is evident that functionally graded concrete beam has more advantages than ordinary concrete since it has more durability and strength characteristics. Scanning electron microscope analysis was also carried out on the red mud functionally graded concrete and fly ash functionally graded concrete. It clearly indicated the pores present in the materials which tends to increase in strength of the concrete.
