STUDY ON STRENGTH AND BEHAVIOR OF CONVENTIONALLY REINFORCED SHORT CONCRETE COLUMNS WITH CEMENT FROM INDUSTRIAL WASTES UNDER UNIAXIAL BENDING

The most ubiquitous and versatile building material, Ordinary Portland Cement (OPC) Suffers from several maladies that inflict may harmful effects on the society. Ever increasing demands for OPC for infrastructural development world over, additional binder production also becomes possible by producing binder totally from industrial wastes; in this category comes fly ash - lime - gypsum (FaL-G) cement. FaL-G cement is a hydraulic cement constituted totally by industrial wastes, fly ash, lime, and gypsum. The cost of FaL-G cement is only 20% of the cost of OPC. FaLG cement concrete works out to about 67.09% of the cost of OPC concrete. The main objective of this investigation was to obtain experimental data, on the strength and behavior of reinforced concrete columns made of FaL-G cement, subjected to combined axial load and uniaxial bending. A total of 10 short columns (5 each with FaL-G and OPC) were cast, the columns were loaded with different eccentricities of 0.1,0.3,0.5 and 0.7 in the universal testing machine of 1000 kN maximum capacity with different loading ranges. The results, deflections and crack width were determined by experimentally and numerically for OPC and Fal-G, comparisons were made with theoretical results to obtain correlation factor.
