Abstract The metal-production industry creates a wide exhibit of strong waste, fluid effluents, and vaporous squanders. stable wastes include slag, powdery materials, sludge, scrap. So feasibility have look at metal slag recycling in fly ash bricks applied laboratory assessments commercial trials on three exceptional styles clay bodies. Crucial necessities consist grinding 90micron size, additi...

The objective of this research is to enhance the properties concrete by using Fly Ash as a partial substitution concrete. Tests carried out on cement are Initial and Final setting time aggregates, specific gravity sieve analysis. mean target strength with given compressive at 28 day quality control level calculated. Concrete blend proportions for first tryout mix calculated casting cube 15mm si...

Reactive uptake coefficients for nitric acid onto size-selected (d(ve) = 102 and 233 nm) sodium chloride aerosols are determined for relative humidities (RH) between 85% and 10%. Both pure sodium chloride and sodium chloride mixed with magnesium chloride (X(Mg/Na) = 0.114, typical of sea salt) are studied. The aerosol is equilibrated with a carrier gas stream at the desired RH and then mixed wi...

Salt crystallization is one of the most dangerous forms degradation affecting frescoes. This phenomenon can lead to cracking, flaking and detachment pictorial layer, ultimately ruining work art. However, characterization soluble salts via chemical analysis be employed determine conditions artifact establish proper restoration and/or conservation strategies adopted. In this archaeometric study, ...

Medium and highly sulfidic tailings are high-volume wastes that can lead to severe environmental damage if not properly managed. Due the high content of sulfide minerals, these undergo weathering put in contact with oxygen water, generating acid mine drainage (AMD). The moderate-to-high is also an important technical limitation for their implementation production construction materials. This pa...

In response to the enormous amounts of coal discard generated during mining and preparation, development an efficient sustainable strategic use this resource is essential. Furthermore, rising urban population over next decades confronted with depletion quality raw materials for building components. To end, study reports new information on morphology, water absorption, flexural strength properti...

Composite thermochemical energy storage (TCES) represents an exciting field of thermal which could address the issue seasonal variance in renewable supply. However, there are open questions about their performance and root cause some observed phenomena. Some researchers have breakdown particles production phase, use. This study seeks to investigate underlying this breakdown. SEM EDX analysis be...

Abstract The small stalactites found on the ceiling at level I near Sutoris shaft in thirteenth-century historic salt mine Bochnia, Poland, are mainly composed of mirabilite (Na 2 SO 4 ·10H O) followed by blödite Mg(SO ) ·4H O). unique presence these two minerals only one location this old underground is attributed to contemporary precipitation from percolating solutions. This can be caused a c...
