Assessment of the ability of MGO based binary binders for the substitution of Portland cement for mortars manufacturing
This article evaluates the ability of a magnesia kiln dust (PC-8) and a commercial calcined MgO (MCB100), combined with ground granulated blastfurnace slag (GGBS), as constituents of binary M-S-H binders. Mortars and pastes ... -
A biological insight of hops wastes vermicomposting by Eisenia Andrei
The study was conducted to assess the feasibility of using Eisenia andrei earthworms for vermicomposting hop remains from a lupulin extraction enterprises for the brewing industry. Vermicomposting process was conducted ... -
Characterization of biomass briquettes from spent coffee grounds and xanthan gum using low pressure and temperature
This paper analyzes the ability of the SCG for briquettes production based on the use of xanthan gum as binder under low-pressure and low-temperature biomass manufacturing conditions. Briquettes were manufactured at room ... -
Conversion of a gasoline engine-generator set to a bi-fuel (hydrogen/gasoline) electronic fuel-injected power unit
The modifications performed to convert a gasoline carbureted engine-generator set to a bi-fuel (hydrogen/gasoline) electronic fuel-injected power unit are described. Main changes affected the gasoline and gas injectors, ... -
Durability of polyester polymer concretes based on metallurgical wastes for the manufacture of construction and building products
Varied target materials can be incorporated into polyester polymer concretes (PPC). This allows natural aggregates to be substituted for different waste products in non-structural polymeric construction and building ... -
Experimental study of the performance and emission characteristics of an adapted commercial four-cylinder spark ignition engine running on hydrogen-methane mixtures
The use of hydrogen/methane mixtures with low methane contents as fuels for internal combustion engines (ICEs) may help to speed up the development of the hydrogen energy market and contribute to the decarbonization of the ... -
Experimental study of the valorization of sulfate soils for use as construction material
This article shows an experimental investigation carried out for the stabilization of a sulfate soil. The stabilization was carried out in two phases: the first phase was the consumption of the sulfate present in the ... -
Feasibility of vermicomposting of spent coffee grounds and silverskin from coffee industries: a laboratory study
In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a ... -
Low energy spent coffee grounds briquetting with organic binders for biomass fuel manufacturing
This paper analyzes the ability of the spent coffee grounds (SCG) for briquettes production with xanthan and guar gums as binders. Briquettes were manufactured at room temperature, at 15%, 20%, 25% and 30% of moisture, at ... -

Recycled granulates manufacturing from spent refractory wastes and magnesium based binder
This paper analyzes the ability of two Spent Refractory Wastes (SRW) for the manufacturing of recycled granulates for construction applications. A binary magnesium oxide and ground granulated blast furnace slag hydraulic ... -
Stabilization of a clay soil using cementing material from spent refractories and ground-granulated blast furnace slag
Nowadays, huge amounts of refractory materials are generated around the world. The majority of them lack valorization methods. This study analyzes the ability of a doloma and two magnesia spent refractory wastes as soil ... -
Sulphate soil stabilisation with magnesium binders for road subgrade construction
This paper analyzes the ability of magnesium oxide-based additives to stabilise a low bearing gypsum marly soil, in order to reach subgrade requirements. This soil was not adequate for stabilisation with lime or cement ... -
Vermicomposting of lavender waste: a biological laboratory investigation
In the present work, lavender waste, a residue of the essential oil extract industry, was used to feed Eisenia andrei with mature horse manure at ratios of 0:100, 25:75, 50:50, 75:25 and 100:0 on dry weight basis. ...
