A Comparative Study on Strength Properties for High Grade Blended Cement Concrete with Different Mineral Admixtures (GGBS, Fly Ash)
Samansai Srinivasa Ravikumar | B.Santhoshimatha
Abstract: Providing a greenery concrete is the aim to the present scenario by the mineral admixtures which having the cementing properties are used as a replacement of the cement which lead to green concrete, and also the industrial waste have discovered the need to disposal of industrial waste, The waste that have to be disposed can be kept to use in some manner, among the industrial waste processing cementations nature can be replaced as binder matter in concrete to apart. A large volume of production of cement leads to emission of many harm full gases like green house gases in atmosphere, which are tends for global warming. Hence, the researchers are currently focused on waste material having cementing properties, which can be added as partial replacement of cement which reduces cement production then the green house gases emission is also reduced, to sustain-able management of the industrial waste, Some of the mineral admixtures like fly ash, Silica fume, Rice Husk ash, Metakoline. In this Project Fly Ash & Ground Granulated Blast Furnaces Slag (GGBS) are used as cementations materials. Fly Ash is an industrial waste products, Ground Granulated Blast Furnaces Slag, (GGBS) which waste from, from an iron manufacturing industry, which may be used as substitute of cement in concrete due to its inherent cementing properties. Due to various codal specifications the binding material replacements of Fly Ash & GGBS have been restricted up to 80 % in maximum. In accordance with above restrictions the replacement variations in binding material have been decoded in a high strength concrete mixture as 10, 20, 30, 40, 50, %of replacement. The research work have been extensively executed in almost all areas of testing like compressive, split tensile, and flexural strength for 28, 56 days.
