Durability Performance of Ferro Geo Polymer Concrete

Abstract

The expansion of the building sector is ultimately driving up the manufacturing of Portland cement, which rises pollution. Consequence of this is global warming. Sustainable alternatives are being used in concrete on a large scale to minimise the impact of greenhouse gases. Concrete made of geo-polymers is one of such alternative. Since Geo Polymer Concrete (GPC) is inherently known for its resistance to aggressive environment, to add to its characteristics, steel wire mesh was incorporated into geo polymer concrete which can largely be termed as “Ferro Geo Polymer Concrete” (FGPC). In the current study, durability properties of FGPC such as resistance to acid attack, Half-Cell Potential (HCP) and resistance to abrasion have been studied. Welded square wire mesh has been used in the specimens with different number of layers. FGPC specimens were compared to GPC specimens of same grade without mesh. Double layered FGPC specimens have shown better resilience to acid attack having weight loss and strength loss of 0.44% and 17.24% when immersed in H2SO4 and 0.45% and 8.4% when immersed in HCL correspondingly. Double layered FGPC has better resistance towards abrasion of concrete with PWL of 2.43% and ADA of 1.07 mm.
