Waste glass is inert and non-degradable which leads to enormous environmental sustainability troubles, but it can be reused in concrete due the potential of pozzolanic activity. This study proposes methods on activity excitation waste powder (WGP) including mechanical, chemical, mechanical-chemical activation. The results showed that mortar containing 30% 75 ?m WGP activated by method was optim...

The utilization of recycled brick aggregate (RBA) and powder (RBP) in cementitious materials helps the reclamation clay waste construction demolition waste. This work studied properties with RBA as RBP supplementary material. has lower apparent density higher water absorption than natural aggregate, an irregular micro-structure contains high content silicon aluminum oxides possesses excellent p...

Omni Processors (OP) are machines which use sludge as a fuel to generate electricity and clean water, but create ash at the same time. In present study, fly bottom investigated materials for potential reuse in construction field. First, granular size, density Blaine finesse determined. Then, chemical composition microstructure obtained by means of X-ray fluorescence Scanning Electron Microscopy...

Treating spent pot lining by the Low Caustic Leaching and Liming (LCLL) process creates an inert non-hazardous residue called LCLL Ash. Ground as a fine powder calcined, Ash showed pozzolanic behavior in cement. The effect of calcination temperatures on reactivity was studied compressive strength activity index, Frattini tests, RILEM R 3 followed XRD analysis. When calcinating at below 800 °C, ...

Pozzolanes are mineral additives that have been widely used in concrete production recently. The main purposes of pozzolana to provide economy and improve various properties concrete. In this study, obsidian which located Pasinler District Erzurum Province has high amount reserves the world with silica content, zinc slag occurring during metal, metal industry mainly Turkey capacity world, pozzo...

This study evaluates the pozzolanicity of Nyiragongo volcano lava flows in Congo by an indirect method using mortars with different rock powder proportions. The clinker used is a locally produced alite clinker, whose chemical and mineralogical composition was determined XRF, Bogue Taylor formulas. were collected from 2002, 2010 2021 eruption sites, characterized CIPW normative mineralogy geomec...

In the last decade, nanomaterials made a major breakthrough in concrete industry by providing with unique properties. Earlier studies have shown improvement early strength of that can accelerate construction process. this study, 1% and 2% nano-silica were added to mixtures contain 30% 70% ground granulated blast-furnace slag (GGBS). Adding GGBS mixture showed an increase compressive 13.5%, 7.8%...

This paper presents the investigations of selected properties concrete containing two fractions fly ash microspheres (FAMs) with grain size up to 200 µm and 500 µm. Concrete mixtures ordinary Portland cement three substitution rates by FAMs, 1.3%, 2.0%, 2.6%, were investigated. For all mixes, constant water–binder ratio (w/b) equal 0.50 was used. The research program included determination chem...
