it has been shown that geopolymerization can transform a wide range of waste aluminosilicate materials into building materials with excellent chemical and physical properties such as fire and acid resistance. in this research work, geopolymerization of construction waste materials with different alkali-activators based on combinations of na2sio3 and naoh has been investigated. a number of syste...

Geopolymer concrete is a more environmentally friendly alternative than conventional because its production does not need cement. Instead, waste materials such as fly ash, rice husk slag, etc. are used. This research studies the effect of activator concentration (6–10 M), curing temperature (40–80 °C) and incorporation ratio thermally mechanically treated recycled aggregate (0–100%) on changes ...

Summary Shallow-depth cementing presents unique challenges due to its low temperature and pore pressure characteristic. The curing process of the cementitious material is typically prolonged at temperatures resulting in a delayed process. use low-density slurry mitigate introduces another challenge, as it leads reduction final compressive strength. On other hand, operation requires develop enou...

The clay soil can present various issues as a construction and infrastructure material. Clay is susceptible to shrinkage swelling, limited bearing capacity, poor drainage, erosion. Several techniques, including stabilization, drainage systems, excavation may alleviate these control the risks associated with soil. There growing interest in stabilization developing environmentally friendly altern...

Geopolymers are a new promising binder manufactured by activation of a solid aluminosilicate source material with a highly alkaline activating solution and aided by heat. Fly ash, considered to be a waste material is rich in silica and alumina and hence can be used as a source material for manufacture of Geopolymers. These binders have been reported to achieve high early strength and better dur...

Geopolymer concrete is generally composed of alumina–silicate materials combined with alkaline solution. plays a vital role to safeguard the environment by way eliminating cement in concrete. The agricultural and industrial disposals include rice husk ash flyash can be used as binding material it activated using Concrete structures usually constitutes significant portion across nation which pie...

Geopolymer concrete has the outstanding characteristics of low carbon emissions and energy consumption while utilizing industrial solid waste, is expected to replace cement as a new generation green building materials. Moreover, with continuous increase in amount concrete, environmental damage resource depletion caused by mining sand gravel aggregates have become increasingly serious. It immine...

The emission of carbon dioxide gas from the cement manufacturing industry has raised concerns about global warming. Geopolymer concrete (GC) is gaining attention as a sustainable and environmentally friendly alternative to traditional concrete. current study focused on using local clay synthesize characterize metakaolin-based GC with varying percentages nanosilica (NS) (1.5%, 3.0%, 4.5%, 6.0%, ...

Abstract Coatings are used as practical solutions against the intrusion of corrosive ions into concrete structures, particularly, in harsh marine environment. In present study, effectiveness using cement-based and geopolymer-based coatings produced by-product materials has been evaluated. Silica fume GGBFS at their optimum dosages were incorporated mortar mixtures a cement replacement, NaOH or ...
