Abstract

This paper presents results of an experimental investigation carried out to study strength and ductility of conventionally reinforced high performance concrete flexural members (i.e. beams) additionally reinforced with steel fibres. Totally ten beams of 150 x 200 x 2200 mm size were cast with and without steel fibres, and tested under two point flexural loading. For casting beams, a high performance concrete (HPC) of M60 grade, and short discrete steel fibres of 0.5 mm diameter were used. The main variables considered in this study are: three different aspect ratios of steel fibres viz. 50, 75 and 100, and in each aspect ratio, three different volume fractions of fibres viz. 0.50%, 0.75% and 1.0%. Test results indicate that addition of steel fibres to conventionally reinforced HPC beam improves strength, ductility and other engineering properties markedly, and the improvement achieved is more when fibre length or fibre content is more. However, the rate of improvement reduces with increase in fibre content. Besides, incorporation of steel fibres improves cracking behaviour of beam by increasing first crack load, and also by forming large number of fine cracks. Furthermore, introduction of steel fibres improves dimensional stability and overall integrity of beam by effective 'fibre bridging action' across cracks. Empirical equations are also proposed to predict strength and ductility of SFRHPC composite beam in terms of 'fibre reinforcing index'.

Abstract

To build high rise building by reducing column sizes and increase available space, to build the super structure of long span bridges and to the durability of bridge decks, a high strength is needed. High strength concrete was used in South Wacker in Chicago of 80 Mpa, Baynunah Tower in Abu Dhabi of 80 Mpa and Frankfurt Trianon in Germany of 125 Mpa. If high strength concrete is self-compacting, the production of densely reinforced building element from high strength concrete with high homogeneity would be an easy work. In the present experimental investigation, attempts are made to study the comparative study of flexural behaviour of High Strength hybrid fibre reinforced self compacting concrete beams of M 100 grade with addition of varying percentages of crimped steel fibers 0, 0.5,1.0, 1.5% and Glass fibers 0%, 0.03%. The studies indicated that the addition of glass fibre and steel fibers in certain proportions in High Strength hybrid fibre reinforced self compacting concrete beams had contributed towards development of high performance and high strength concrete which is the need of the hour.

Abstract

The Seismic behavior of buildings critically depends on its overall shape, size, and configuration. Buildings with re-entrant corners in plan are considered to be irregular by many seismic design codes. The seismic behavior of RC buildings with symmetrical floor plan shapes having re-entrant corners (H shape, + shape) is investigated in this paper. Various types of building plan configurations with increasing amount of irregularity (A/L ratio) as per IS 1893 code are modelled and analyzed using ETABS 2015 software. A regular plan building is also modelled as a bench mark problem to compare all irregular models. Response spectrum analysis has been carried out for all these models located in seismic zone V of India. Various dynamic parameters such as Story displacement, Story drift and Base shear are compared and some useful conclusions are drawn.

Abstract

This study presents strength properties of concrete reinforced with steel-polypropylene hybrid concrete and compared it with steel fiber reinforced concrete and polypropylene concrete. Hybrid Fiber Reinforced Concrete (HFRC) is formed from a combination of different types of fibers, which differ in material properties, remain bonded together when added in concrete and retain their identities and properties. The combining of fibers, often called hybridization, is investigated for a M40 grade concrete. The fibers used polypropylene and steel (crimped) fibres with different fiber proportions of steel and polypropylene. Compressive test and split tensile strength were performed and finally the result was extensively analyzed to associate with above fiber combinations. Based on experimental studies, the paper identifies fiber combinations that demonstrate maximum compressive and split tensile strength of concrete.

Abstract

In the present paper the pozzolanic effect of two different mineral admixtures( Fly ash and Ground granulated Blast Furnace slag) in Roller compacted concrete (RCC) was studied quantitatively with various strength indices namely specific strength ratio(R), index of specific strength(K) and contribution rate of pozzolanic effect to strength(P). Cement was partially replaced with mineral admixtures by 10%, 20%, 30%, 40%, 50% and 60% by weight respectively for Fly ash (FA) and Ground granulated Blast Furnace slag (GGBS). Besides the strength properties, these indices showed that early curing age, specific strength of Fly ash Roller Compacted Concrete (FRCC) decreases with increase in FA content, whereas the specific strength of GGBS Roller Compacted Concrete (GRCC) increases with increase in GGBS content. After 90 days of Curing, the contribution of mineral admixture effect on Flexural Strength of FRCC and GRCC are 50% and 63 % respectively.
