Geotechnical Characterization Cement - Fly Ash –fibers Mix
The fly ash is a waste produced mostly from the burning of coal in thermal power station which contributes to environmental pollution. It is naturally-cementitious coal combustion by-product. Many studies have been reported in the literature on the performance evaluation of soil – fly ash system as well soil-fly ashfiber system. Although ample studies have been reported with randomly distribute...
متن کاملGlass Fiber Reinforced with Partial Replacement of Cement with Fly Ash
Concrete is one of the most widely used construction material in today’s world. Cement is one of the essential constituents of the concrete. Environmental issues are also playing a vital role in today’s world, the production of cement one of the major constituent of concrete leads to release the of a significant amount of carbon dioxide a greenhouse gas contributing 7% of greenhouse gas emissio...
متن کاملEffect of Copolymer Latexes on Physicomechanical Properties of Mortar Containing High Volume Fly Ash as a Replacement Material of Cement
This paper investigates the physicomechanical properties of mortar containing high volume of fly ash (FA) as partial replacement of cement in presence of copolymer latexes. Portland cement (PC) was partially replaced with 0, 10, 20, 30 50, and 60% FA. Copolymer latexes were used based on 2-hydroxyethyl acrylate (2-HEA) and 2-hydroxymethylacrylate (2-HEMA). Testing included workability, setting ...
متن کاملBagasse ash and rice husk ash as cement replacement in self-compacting concrete
In studies conducted to determine the workability of concrete, the bagasse ash and rice husk ash were added as a partial replacement for cement. Trial mixes with the varying water cement ratio, replacement percentage, quantity of super plasticizer and viscosity modifying agent, were prepared and tested. The results were used as the basis for defining three optimum cement replacement mix proport...
متن کاملCorrosion Resistance Performance of Fly Ash Blended Cement Concretes
Durability of reinforced concrete with respect to corrosion of reinforcement is one of the major aspects to be considered in the management of civil infrastructure systems. An accelerated laboratory test method developed at SERC where the concrete specimen containing rebar is subjected to polarization under a constant voltage in a sodium chloride solution. It is found that the current response ...
