AN EXPERIMENTAL STUDY ON THE BEHAVIOUR OF CONCRETE ON PARTIAL REPLACEMENT OF CEMENT WITH GROUND GRANULATED BLAST FURNACE SLAG

Abstract

Concrete is the most widely used material in construction industry due to its high strength and stability. However environmental sustainability is at stake due to the damage caused by the extraction of raw materials and carbon-dioxide emission during cement manufacturing, so the industry is looking for the alternative supplementary cementitious materials. GGBS is useful in the design and development of high quality cement paste. The usage of GGBS serves as a replacement and also it is a by-product which is used as
eco-friendly material by utilizing the product without dumping which is produced from the industrial waste from the blast furnace used to make iron. Use of GGBS not only reduces the cost of production but also helps to reduce the impact on environment by consuming material which is considered as a waste product. The present study is conducted to investigate and evaluate the workability and strength characteristics of concrete of M20 grade concrete at different ages with partial replacement of cement with ground granulated blast furnace slag (GGBS) replacing cement in percentages of 10%,20%,30%,40% by weight. The mixes were designed using IS code. The concrete mixture produced in the form of cubes, cylinders, prisms are tested for compressive strength, split tensile strength and flexural strength. The Durability of concrete against acid attack was done after 91 days treatment with H2SO4.
