REVIEW PAPER ON GGBS AND TANNERY WASTE TO COMPLETE REPLACEMENT OF CEMENT

Abstract

The most crisis the Earth is against nowadays is the environmental pollution and climatic change. Majorly in the construction field the production of OPC causes the emission of Co2 and some harmful pollutants thus results in the environmental pollution. We have the options to reduce the pollution crisis on environment by involving the industrial wastages as a construction material. In this project the geo polymer concrete is prepared by the combination of GGBS, Tannery waste and alkaline solution. The Alkaline solution is for the polymerization process, and it is prepared by the combination of (NaOH) Sodium hydroxide and (Na2SiO3) Sodium silicate. Different molarities of NaOH solution (i.e.) 2M, 4M, 6M, 8M, 10M, 16M are there to prepare the alkaline solution but 16M only used in this project and compressive strength at different ages of each cubes of Tannery waste at different proportion 5%, 10%, 15%, 20 must be calculated and compared to find the optimum one.

SEM (Scanning Electron Microscope) analysis test also conducted to analyse GGBS and Tannery waste. The sieve and water absorption tests are also conducted for the fine aggregate and coarse aggregate. The cube specimen of size 150mmX150mmX150mm are taken. Two different curing techniques are carried out before testing (i.e.) by water curing or by oven curing to accelerate the strength and durability aspects. These geo polymer concrete cubes are tested for the compressive strength at the ages of 1,7,14 and 28th day. The testes conducted on the geo polymer concrete cubes are compression strength, water absorption and bulk density.
