Abstract Geopolymer (GP) has recently emerged as a novel and environmental friendly alternative to conventional soil stabilization products like lime Ordinary Portland Cement (OPC), which adversely affect the environment. This article emphasizes GPs produced from high calcium class C fly ash (CFA) an alkali activator comprising sodium hydroxide silicate solution for sand stabilization. The expe...

Currently, innovation continues to be developed replace cement with other materials so that the use of as a building material can reduced. Utilization coal waste (fly ash) is an alternative subtitude cement. From previous studies, fly ash mixed alkaline in form NaOH and Na2SiO3 ratio 1:5 produce geopolymer concrete. This concrete research was continued by adding bendrat wire fibers into mixture...

Portland cement (PC) is a common material used in civil infrastructure engineering. Cement production emits roughly 2.2 billion tons of CO2 per year, contributing 8% global emissions 2016. This contributes to almost half the calcination process, and together with thermal combustion, clinker generation could be responsible for 90% sector’s emissions. One effective technique dealing these industr...

Concrete is a versatile construction material used along with reinforcement. made up of binder materials and aggregates. Cement primary to produce conventional concrete. Carbon dioxide emissions in the atmosphere are symptom issue related Portland cement manufacture. It estimated that one ton produced releases an equal amount CO2 into atmosphere. On other hand, many industrial wastes dumped ope...

This paper presents the results of a study on the effect of temperature on geopolymers manufactured using pozzolanic materials (fly ash). In this paper, we report on our investigation of the performance of porous geopolymers made with fly ash after exposure to temperatures from 600 °C up to 1000 °C. The research methodology consisted of pozzolanic materials (fly ash) synthesized with a mixture ...

This study reports on the microstructure, compressive strength, and drying shrinkage of metakaolin (MK) based geopolymers produced by partially replacing MK by oil palm ash (OPA). The OPA was used as raw material producing different molar ratios of SiO₂/Al₂O₃ and CaO/SiO₂. The geopolymer samples were cured at 80°C for 1, 2, or 4 hours and kept at ambient temperature until testing. The compressi...

Many experimentation and researchers were made in the recent decades concrete advancement field of technology given a major focus. In years research, many new replacement materials identified further details studies over to have clear better idea about material. this study, binder which is be cement basically replaced with combination Alccofine-1203(A), Metakaolin (MK), Ground Granulated Blast-...

Recycling of usable resources from waste must be prioritized to adhere the circular economy policy implemented worldwide. This study aims use wastewater sludge incineration ash (WSIA), which is a by-product treatment processes, in 3D printing industry as sustainable material. First, we explored stability incinerated generated facility Seoul by evaluating its physical (water content, organic mat...

Environmental concerns have prompted researchers to focus on the development of alternative building materials like geopolymer concrete. However, their implementation requires curing beyond 60°C, which limits application sites. This study aims design a concrete at room temperature (30 ± 5°C) in laboratory Burkina Faso using metakaolin-based binder activated by an alkaline solution NaOH and natu...
