Study on Partial Replacement of Fine Aggregate with Red Soil in Concrete
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Many researchers are dealing with various types of admixtures to improve the mechanical and durability properties of concrete. In this present investigation, red soil is taken as an admixture to enhance the performance of concrete. An experimental investigation is carried out to study the behaviour of concrete by replacing the fine aggregate with locally available red soil. It involves a certain tests to find the quality improvement of concrete when red soil is added to it. The partial replacement of sand with red soil has been done according to the specific mix proportion to gain good strength in concrete and to calculate the imperviousness of red soil and also to find the special features of red soil which has the anti pest control in it. Mechanical properties such as compressive strength, split tensile strength, flexural strength and durability properties such as porosity, water permeability tests has been carried out for red soil mixed concrete and plain concrete to differentiate the strength and imperviousness in it . From the chemical properties of red soil, it is found that by replacing the fine aggregate with red soil turns the concrete as anti pest control. This red soil and river sand samples are first taken for preliminary test such as the sieve analysis test. Noticeably the red soil is of uniform size and so it is graded as poorly graded soil but the river sand is not finer as compared to the red soil. The partial replacement of sand in concrete has been done using red soil in a mix proportion of 1:1.5:2.75 which gives the significant improvement in strength and imperviousness. The characteristics of red soil has a great impact on strength, imperviousness and anti pest control. After conducting all these tests, red soil is found suitable for concrete as an admixture of it which can be used in construction of buildings.
