Conventional concretes fail to prevent the intrusion of moisture and aggressive ions adequately. The use supplementary cementing composite ma...

Abstract—In this study, the Compressive strength of concretes made with Ground Granulated Blast furnace Slag (GGBS), Pulverised Fuel Ash (PFA), Rice Husk Ash (RHA) and Waste Glass Powder (WGP) after they were exposed 780C (exposure duration of around 60 minutes) and then allowed to cool down gradually in the furnace for about 280 minutes at water binder ratio of 0.50 was investigated. GGBS, PFA...

This paper focuses on the simulation and visualisation of coal combustion in the pulverised coal boilers. It is important to find optimal boiler configurations (both for the ecological and economical reasons), determine appropriate combustibles, optimize process of combustion, etc. These tasks are typically solved using traditional Computational Fluid Dynamics (CFD) methods that are in general ...

Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill, Rolls Crusher and Ball Mill. The pulverised samples were sieved to obtain four particle size fractions and temperature-programmed combustion (TPC) was used for the evaluation of their combustion behaviour. In addition, three coals of different hardness and rank were mixed in various proportions...

Thermal power stations using pulverised coal as fuel, generate large quantity of ash as waste by product, which poses dual problem of environment and disposal. Flyash is a versatile material with many possible applications such as land filling and in land reclamation of low lying areas. An experimental investigation has been carried out to study the behaviour of compacted ash overlying sand dep...
