Utilisation of fly ash and Ground Granulated Blast Slag as an alternative material in concrete reduces the use of OPC in concrete. Evolution of geopolymer concrete cured at ambient temperature broadens its suitability and applicability to concrete based structures. This paper presents the mix proportions and outcome of an experimental study on the density and compressive strength of geopolymer ...

In this fast-moving construction world, the main problem of conventional concrete is formation carbon-di-oxide (CO2). This due to emission CO2 during production cement. As a solution for this, Geopolymer (GPC) was invented it has capability produce nil emissions. addition in our modern world everyone wished complete project within short span time but takes more setting and curing. disadvantage ...

Clay is a naturally occurring material that can be converted to different clay minerals through thermal treatments, and used for the development of products. Clays have been applications in sectors. Detailed information regarding these materials construction industry are described. has as supplementary cementitious Portland cement (OPC) mortars concretes. These decrease raw CO2 emissions during...

This paper discusses the influence of fiber reinforcement on properties geopolymer concrete composites, based fly ash, ground granulated blast furnace slag and metakaolin. Traditional composites are brittle in nature due to low tensile strength. The inclusion fibrous material alters behavior along with a significant improvement mechanical i.e., toughness, strain flexural Ordinary Portland cemen...

Protection, restoration, and regeneration of aquatic habitats are an increasingly important issue requiring intensive research. In the marine environment, artificial reefs may be deployed to help offset habitat loss, increase local biodiversity stimulate recovery ecosystems. This study aimed at fabrication by 3D printing. framework European INTERREG Atlantic Area collaborative project “3DPARE”,...

In this work, the effects of slag addition on geopolymerization process and sulfate resistance alkali-activated cement were studied. The substitution metakaolin by increased reactivity precursors, contributing to a higher reaction rate accelerating process. mechanical properties significantly improved with incorporation slag. results show that transformation gel phases development pore structur...

This study proposes potential replacement for the Portland-based cement, which is a common sealant used in deep high-temperature geothermal wellbore completions. The experimental laboratory studies were focussed on alkali-activated aluminosilicates. It was proven, that so-called, geopolymer-based sealing systems exhibit high compressive and flexural strength at elevated temperatures, good resis...

Geopolymers are a class of material that could potentially be used for sealing and repair damaged concrete structures. This application is important both decommissioning activities standard industrial applications. The purpose this article to investigate the interface between ordinary Portland cement geopolymer. surface microstructure investigated by SEM, EDX, micro-Raman after embedding in geo...
