STUDY ON THE MECHANICAL PROPERTIES OF HIGH STRENGTH CONCRETE USING G.G.B.S AND SILICA FUME AS PARTIAL REPLACEMENT OF CEMENT. Vishvjeetsinh Dilipsinh Rana1, Aakash Rajeshkumar Suthar 2 1 Student Civil Engineering Department, L.J.I.E.T. Ahmadabad, Gujarat, India 2 Professor Civil Engineering Department, L.J.I.E.T. Ahmadabad, Gujarat, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - The aim of this investigation is to assess how mineral admixtures can enhance the compressive and flexural properties
of concrete by partially substituting cement. The research will involve conducting trial and error experiments to explore the impact of Silica fume and GGBS when partially replacing cement while maintaining a constant water-cement ratio to produce highstrength concrete. To achieve this, concrete samples of varying percentages of Silica Fume (5%, 8%, and 10%) and GGBS (25-50%) will be casted and evaluated, with partial substitution of cement, in sizes of 150mmx150mmx150mm (cube) and 500 X 100 X 100 mm (beam). The goal of the study is to identify the optimal percentage of Silica fume and GGBS that will provide the highest compressive strength (M65, M70, M75) and flexural strength. The research involves an analysis of how mineral admixtures such as Silica fume and GGBS can be effectively used in cement and concrete construction materials. Key Words: Cement, Concrete, Construction Material, Mix Design, Silica Fume, GGBS
I.INTRODUCTION The utilization of triple blended concrete is a method that improves the strength characteristics of concrete by altering its chemical composition, particle size distribution, and fineness. It involves incorporating additives like pozzolana, granulated slag, or inert fillers to modify the concrete's properties. As a result, this technique has led to the development of different cement formulations that conform to both national and international standards. Triple blended cement serves as a promising alternative to mineral admixtures such as fly ash, silica fume, and granulated slag. This type of concrete, known as triple blended concrete, exhibits exceptional physical, chemical, and mechanical properties, making it particularly advantageous in construction applications.
II. MATERIAL AND METHOD General In this chapter, you will find comprehensive details regarding the materials used. This includes information about the characteristics of the materials, the types of materials employed, and their respective proportions. Materials The materials utilized for the study consist of processed Silica Fume and GGBS as source materials, ordinary Portland cement, aggregates, water, and an admixture. Cement: The experimental work utilizes 53 grade ordinary Portland cement. The specific type of cement employed for the experiments can be seen in Figure 1.1. The chemical properties of the cement are outlined in Table 1.1.1, while Table 1.1.2 presents the physical properties of the cement.
