Abstract

In recent technological applications, use of Geo-fabric materials have gained importance in various civil engineering works, Geotechnical, Transportation systems, Hydraulic and other applications like Embankments, Irrigation structures, Airfields, Agriculture etc (Shukla, 2002). These Geo-fabrics have been particularly useful in reinforced soil systems which have led to economical civil engineering structural elements. These materials exhibit appreciable tensile strength and bond strength. The concrete members are brittle materials, to withstand the tensile strength of the members as they are reinforced by steel bars. In recent days, because of environmental safety concepts the replacements of construction materials are widely done in the research fields. Inparticular, partial replacement of cement and steel has got more significant in research field because of its high emission of carbon gases during the production. In the view of these concepts, the present paper deals with checking the Biaxial Geo-grid by adding appropriate volume of fraction to fresh concrete mix and study the strength criteria for different curing periods as per Indian standards (BIS, 1959, 2000, 2009). The compressive, Split tensile and flexural strength characteristics are studied with the help of concrete cubes, Cylinders, and prisms With conventional and Geo-grid proportioned specimens. The study shows that the addition of Geo-grids shows no appreciable change in compression strength at initial age of curing but it shows better performance in flexure by which is stands more than 10% higher strength compared to regular conventional specimens not proportioned with Geo-grids. Basic tests are carried at concrete age of 7days, 14 days and 28 days by considering 6 specimens in each case and finally from tests results it is concluded that these Geo-grids are capable of withstanding failure under flexure that further increases the shear, strength also it is recommended that it can be used for further partial replacement of reinforcements in concrete members.
