Abstract
This paper illustrates admixtures advantages such as fly ash, silica fume and granulated blast furnace slag in concrete as it influence the properties of it. The properties such as compression, split tensile and flexural strength which are of mechanical for the specimens of different grades are obtained. The specimens are of M35 grade which includes fly ash are in proportions 5%,10% and 15% , silica fume of 5%,10% and 15% together as the replacement of cement and granulated blast furnace slag of 5%,10% and 15% as the small replacement of filler material which is fine aggregate. The water cement ratio by trials is kept as 0.45 for all proportions. The ground granulated blast furnace sand improves the compactness and slows the chemical activity. The use of different admixtures in concrete gives a high performance in concrete construction. The mechanical properties such as compression, split tensile strength and flexural strength are determined on 28 day.
