An assessment on the durability performance of fly ash-clay based geopolymer mortar containing clay enhanced with lime and GGBS

Geopolymer mortar is an innovative mortar using fly ash waste as an alternative to cement. The development of advanced fiber geopolymer mortar materials is an alternative solution to the weaknesses and shortcomings of conventional materials so that they have the ability to reduce and even absorb sound intensity and prevent noise propagation in overcoming noise problems in the field of building construction. Many factors can affect sound absorption, including the type of aggregate, modification of material composition that has a density level in fiber geopolymer mortar. The development of fiber geopolymer mortar can be developed in the construction field to reduce sound frequency and improve sound insulation. There are also different measurement mechanisms to determine the performance of the material in improving sound quality. This paper aims to review the performance of sound-absorbing fiber geopolymer mortar. This review is expected to provide insight into the development of fiber geopolymer mortar in building construction to improve comfort and reduce noise pollution.

“…The results showed how using Pozzolana can impact the environment. Lekshmi et al examined the endurance accomplishment of clay-containing geopolymer mortars based on low calcium fly ash and assessed water absorption, sorptivity, abrasion resistance, acid attack resistance, and sulphate attack resistance of the ideal blend [16]. Using pozzolana cement in place of ordinary cement has been considered as a major research gap.…”

The research looks at the characteristics of Normal Concrete (NC) by testing small square blocks and larger cylindrical samples to see how they respond under pressure and strain. The flexibility of different Ground Granulated Blast Furnace Slag (GGBS) and silica fume mixtures is measured using the Saenz Model, and the results are shown in graphs comparing stress and strain. This study examines how substituting materials like GGBS and adding materials like silica fume to concrete affects its strength and environmental impact. Seven mix designs of M35 grade concrete were prepared to study strength, toughness, ability to stretch, and absorb energy, and how stress and strain are related. The results show that substituting 35% GGBS and adding 10% silica fume is best for improving the strength of NC when compressed. The suggested mathematical equations for how well NC can resist being compressed match up closely with the real-life test results. However, the measured factors show that incorporating 30% GGBS with 5% and 15% silica fume in the concrete causes more environmental harm. However, the NC without pozzolana shows a lower measure of its environmental impact, except for its contribution to climate change.

“…The aluminosilicate rich source materials are activated by an alkaline medium. Fly ash [3], ground granulated blast furnace slag (GGBS) [4], red mud [5], rice husk ash [6], palm oil fuel ash [7], metakaolin [8], sugarcane bagasse ash [9], dolomite [10][11][12][13], clay [14][15][16][17], etc are commonly used as source materials in geopolymers. The combination of sodium based silicates and hydroxides or potassium based silicates and hydroxides, as alkaline activators have been employed in developing geopolymer binders [12].…”

The enormous demand for concrete as a construction material over the globe has proliferated the production of cement. It has been reported that the production of one ton of cement produces approximately one ton of carbon dioxide gas to the atmosphere. In geopolymer system, the use of cement is eliminated by using aluminosilicate rich industrial and agricultural waste as source material, which is activated by an alkaline medium. Biomineralization in concrete by using microorganisms is a technique used to enhance the mechanical and durability performance of concrete by imparting self-healing of cracks generated in the system. This paper reviews the feasibility of microbial inclusion in geopolymers. In this review, the mechanical and durability characteristics of microbial geopolymer binders along with the observations of microstructural characterization are elucidated. The mechanical properties in terms of compressive strength, split tensile strength and flexural strength are studied systematically from the existing literature. The durability studies of bio-mineralized geopolymer binder (BMGP) in terms of water absorption, sorptivity, acid attack resistance, sulphate attack resistance and resistance towards freeze thaw effect are analysed in the study. Also, the possible applications of biomineralized microbial geopolymer concrete are critically reviewed in this paper
