Amorphous silica and alumina of metakaolin are used to adjust the bulk composition of black (BSS) and white (WSS) steel slag to prepare alkaliactivated (AAS) mortars consolidated at room temperature. The mixdesign also includes also the addition of semicrystalline matrix of river sand to the metakaolin/steel powders. The results showed that high strength of the steel slag/metakaolin mortars ...

· In countries such as India and Italy, organized crime groups have emerged as prominent illegal suppliers of soil and sand. The proposed study focuses on an understudied research area at the intersection between organized crime and environmental crimes, and offers a transcomparative study of illegal soil and sand mining conducted by Indian and Italian .
Chromite sand has the following physical and chemical properties: Melting point of 2150°C. Good thermal conductivity. Good resistance to thermal shock. Excellent resistance to metal penetration or burnon. Resists slag attack. High dimensional stability. Standard grades. LKAB Minerals offer one standard grade.

Journal description. Disseminates information relating to the development of new civil engineering materials, the processing and field production of the materials, the evaluation of construction ...
AAS with alkali content of 3% of slag mass, modulus of, sand slag ratio of, and water slag ratio of was adopted as the substrate material for mortar and ferrocement specimens. SSWM with a grid size of mm and a wire diameter of mm was adopted as the reinforcement. Five groups of specimens, including mesh, mortar, and ferrocement with one, .
The molten material flows through a filter medium for the purpose of separation of slags, sand particles or other oxidic impurities (s. Casting filter).. Purifiion of used air, exhaust air, and dustcarrying hot gasses in industrial plants in accordance with emission laws and other statutory rules and regulations for keeping air clean is also referred to as filtering (s.
Investigation of strength of concrete by replacement of sand with copper slag and cement with sugarcane bagasse ash. This investigational study conducted to observe the potential of Sugarcane Bagasse Ash as a cement replacing material which is similar to that of Portland Pozzolana Cement and Copper slag as a fine aggregate replacement material. Seven different concrete mixes with the .

significantly less dust than sand and slag abrasives. The type of abrasive used in a particular appliion is usually specific to the blasting method. Dry blasting is usually done with sand, metallic grit or shot, aluminum oxide (alumina), or silicon carbide. Wet blasters are operated with either sand, glass beads, or other materials that remain suspended in water. Emissions And ...
region, byproducts such as coal wash and steel furnace slag were considered to be potential structural fill material for the above tide level. In this study the behaviour of mixtures of coal wash and steel furnace slag where the content of coal wash ranged from 0% (, pure steel furnace slag) to (, pure coal wash) has been studied ...

· This work focuses on the use of copper slag, as a partial replacement of sand for use in cement concrete and building construction. Cement mortar mixtures prepared with fine aggregate made up of different proportions of copper slag and sand were tested for use as masonry mortars and plastering. Three masonry wall panels of dimensions 1 × 1 m were .
· Alkaliactivated slag (AAS) mortars were prepared using pottery sand as a fine aggregate in a ratio of 1 : using a blend of sodium silie and NaOH as an alkaline activator at room temperature. The effects of sodium oxide content and silie moduli on the setting time, fluidity, consistency, compressive strength, and drying shrinkage of different AAS mortars .
Ground Granulated Blast Furnace Slag (GGBS) is a cement substitute that improves durability and also the environmental credentials of concrete mixes. It is a byproduct of the ironmaking industry. For every tonne of GGBS used in a concrete mix, the embodied CO 2 levels are reduced by around 900 kg compared to the use of one tonne of traditional Portland Cement. What is GGBFS? The abbreviation ...
Open Access journals are the major source of knowledge for young and aspiring generations who are keen in pursuing a career in sciences. This system provides easy access to networks of scientific that contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholarly explore these works extensively.

The species assemblages of benthic ciliates from two adjacent loions at a sandy shore of the Ligurian Sea (Italy) are examined and compared. The environmental conditions are very similar, ex cept that one loion is more exposed to hydrodynamic disturban ce than the other. Sediment samples (168 sandy samples from each station) for the identifiion and enumeration of ciliates were ...
