This paper describes the experimental work on Hybrid Fibre Reinforced High Performance Concrete using three types of fibres namely steel, glass and polyester fibres of a reputed brand. Silica fume was added as a mineral admixture to partially replace the cement in concrete and a super plasticizer was used to get the desired workability. A comparison with steel fibre reinforced concrete and plain concrete showed significant improvement in the strengths of the hybrid fibre reinforced concrete due to the inclusion of both fibres and silica fume.

The synthesis of various substituted 4-methoxy-1H-quinolin-2-thiones from various substituted aniline with malonic acid, phosphorousoxychloride, sodium methoxide glacial acetic acid and thiourea under different conditions is described. All these substituted 4-methoxy-1H-quinolin-2-thiones were synthesized from four steps; the first step involved the synthesis of substituted 2,4-dichloro quinoline from aniline (substituted), with malonic acid and phosphorous-oxychloride. In the second step, the substituted 2,4-dichloro compound was heated with freshly prepared methanolic sodium methoxide solution to give 2,4-dimethoxy quinoline compounds, it was then refluxed with glacial acetic acid and hydrochloric acid to get the substituted 4-methoxy-1H-quinolin- 2-one. The final steps involves with an objective of introducing a chloro in the position 2 of the quinolone system, the substituted 4-methoxy-1H-quinolin-2-one was refluxed with distilled PoCl 3 chloroform. The substituted 2-chloro-4-methoxy quinoline was then refluxed with thiourea and alcohol to get substituted 4-methoxy-1H-quinolin-2-thiones. The purity of the synthesized compound was judged by their C, H and N analysis and the structure was analyzed on the basics of mass, FT-IR and 1H NMR. Source

Bagasse is a cellulose fiber that is obtained as a residue from sugar cane after the juice is extracted in sugar mill. In earlier times, it was considered as a waste in sugar industry and was usually burnt for disposing. Later, due to the fuel crisis in 1970 and consequent increase in fuel prices, the concept of bagasse being regarded as a solid waste was changed into a useful biomass fuel for combustion in boilers. Also, there is an increasing demand for bagasse as raw material for paper, furniture and other industries. A typical 2500 TCD capacity sugar mill produces 750 tons of bagasse per day (30%). The moisture content (MC) of bagasse obtained from exit of sugar mill varies from 45 — 55 %. The bagasse which is used as fuel for boilers is normally combusted without drying due to the need for installing separate auxiliary equipment. The GCV of bagasse ranges from around 9600 kJ/kg for 50 % MC to 14500 kJ/kg for 25 % MC. Due to the presence of inherent & surface moisture, it is obvious that the calorific value of bagasse gets lowered and leads to high specific fuel consumption. As a rule of thumb, for every 20° C reduction in back end temperature there is 1% increase in boiler efficiency and for 10% reduction in excess air 0.4% increase in boiler efficiency were observed. Similarly, for every 1% reduction in bagasse MC, 0.8 % increase in boiler efficiency can be achieved. This necessitates the need for drying bagasse before being fed into the boiler. Despite many efforts put in by researchers for drying bagasse, the drying solutions were not successful due to its complex drying characteristics. On analyzing the different drier models, the major findings were that the flue gas obtained from boiler cannot be used for bagasse drying (by direct contact method), flash drier though technically possible is not energy efficient due to high energy consumption, rotary and fluid bed driers possess the disadvantage of inability to handle bagasse due to its abysmally low particle density. As a solution for drying bagasse, without negotiating the performance and energy involved, a percolating type batch drier has been designed. The objective of the project is to design, fabricate and analyze the drier performance experimentally and obtain the technical feasibility of the drying system for implementation in sugar mills. It has been observed that the moisture content of bagasse has been reduced by 15% in 2 hours’ time period with the new developed drier. © Research India Publications. Source

The main requirements of disaster resistant structures are good ductility and energy absorption capacity. Fibre reinforced concrete is one which possesses high tensile and flexural strength, improved ductility and high energy absorption capacity than the conventional concrete against dynamic loads. The use of hybrid fibres in the concrete mixture can produce a composite with better engineering properties than that of individual fibres in concrete. This paper deals with the experimental study on the flexural behavior of High Performance Hybrid Fibre Reinforced Concrete beams cast with steel and glass fibres subjected to cyclic loading. The various parameters such as load carrying capacity, stiffness degradation, ductility characteristics and energy absorption capacity of HPHFRC beams were compared with that of RCC beam. It has been observed that the high performance hybrid fibre reinforced concrete beam performs well in flexure when compared to concrete beams with mono fibre and without fibre. The combination of different types of fibres increases the ductility and energy absorption capacity significantly. Also the presence of hybrid fibres helps in reducing the crack width and causes lesser damages to the beams. Source
