Microstructure And Mechanical Properties

This paper presents the results of an experimental study on the behavior of fly ash-, bottom ash-, and blended fly and bottom ash-based geopolymer concrete (GPC) cured at ambient temperature. Four bathes of GPC were manufactured to investigate the influence of the fly ash-to-bottom ash mass ratio on the microstructure, compressive strength and elastic modulus of GPC. All the results indicate that the mass ratio of fly ash-to-bottom ash significantly affects the microstructure and mechanical properties of GPCs

Structural Applications

To combat the present situation of greenhouse gases emission from cement production, a promising solution is to utilise supplementary cementitious by-product materials such as fly ash to produce green concrete known as Geopolymer concrete (GPC). However, despite fly ash based concrete is a promising substitute for ordinary Portland cement (OPC) concrete, it is not yet being utilised to its full potential for structural applications.  And so, to utilise green concrete to its full potential, this paper aim is to conduct an experimental study that will integrate fly ash based concrete within steel-concrete composite beams. The research will include casting of composite beams with GPC mix, and an OPC concrete as a reference mix designed according to British Standards. To determine the ultimate moment capacity, a total of Four (4) composite beams comprised of coventional and Bondek steel profile concrete slab are designed and tested according to Australian Standards. From the test results, it was found that composite beam with conventionalconcrete slab outperformed the beams with Bondek profile sheeting. Also, regarding of ultimate bending moment capacity, the composite beam with geopolymer concrete experienced almost identical to OPC composite beam.

Abstract In this study concentrated on the development of GPC by using industrial waste products such as fly ash, alccofine (1203) and GGBS. GPC is an advanced eco-friendly concrete manufactured by activating source minerals rich in alumina and silica by alkaline liquids to form aluminosilicates based on inorganic polymers. Where cement was complete replaced with mix proportion of 50% fly ash, 25% alccofine (1203) and 25% GGBS for different molarities (8M, 10M and 12M) of alkaline activators which is solving the problem of unsustainable usage of limestone and pollutant related to the manufacturing process of cement. The present paper reports the cube compressive strength, cylindrical split tensile strength and flexural strength of GPC and which is compared with M25 grade of control specimens. It was observed that the strength of GPC is increased than normal concrete as molarities increases of 8 M, 10M and 12M. The paper explains about the effectiveness of fly ash, alccofine (1203) and GGBS materials.
