Durability Properties of Admixture of Fly Ash, Bottom Ash and GBFS

EasyChair Preprint 5475

Abstract

Fly ash, bottom ash and granulated blast furnace slag (GBFS) are industrial wastes materials from thermal power plants and steel industries. Due to stringent disposal laws, it is a challenging issue to dispose-off. It can be used as concrete admixture of above these raw materials by geopolymer techniques. It will reduce the cost of disposal, which includes treatment, transportation, and environmental cost and also reduce consumption of cement. Ordinary Portland cement concrete is very popular in construction but it is not an eco-friendly material because a huge amount of energy consumed for cement production and their consequent a huge amount of CO₂ is released in atmosphere. This article especially emphasized the use of raw material as eco-friendly and effect in compressive strength of their product concrete exposed in various chemical environments, various exposure duration and various silicon/aluminium ratios. The compressive strength of sample was determined in 1% and 3% of H₂SO₄, CH₃COOH, Na₂SO₄, MgSO₄, and NaCl solutions for exposure 7, 28 and 60 days. The reduction in compressive strength was found in the entire sample in each condition.

Keyphrases: Geopolymer, compressive strength, waste material
