Thermal insulation and mechanical properties of a specially improved insulation plaster under freezing-thawing and high-temperature conditions
(Oxford University Press, 2023)
In this study, the effects of heat preservation and the resistance to environmental conditions of ready-made insulating sludge used in the interior and exterior facades of the buildings were investigated. The insulation ...
Effect of content and length of polypropylene fibers on strength and microstructure of cementitious tailings-waste rock fill
(MDPI, 2023)
The mechanical strength properties of cemented tailings backfill are very important for the safe and environmentally friendly mining of mineral resources. To check the impact of polypropylene fiber on strength and ...
Experimental performance assessment of a novel insulation plaster as an energy-efficient retrofit solution for external walls: A key building material towards low/zero carbon buildings
(Elsevier, 2023)
Thermal insulation plasters have become the focus of attention in the building sector. Among the most important reasons for this is the high thermal energy losses of the buildings. Since conventional briquettes used in ...
On the effect of green nonstructural materials on scour reduction downstream of grid dissipators
(IWA Publishing, 2023)
In this study, a nonstructural and eco-friendly solution has been used to reduce scouring downstream of screens. Upstream of the screen are stilling basins protected against scouring, but downstream locations are subjected ...
Cementitious backfill with partial replacement of Cu-rich mine tailings by sand: rheological, mechanical and microstructural properties
(MDPI, 2023)
The thinning of tailings gradation during ore processing leads to a sizeable fall in the strength of cementitious paste backfill (CPB), increases operational risks, and encourages researchers to use alternative economic ...
Admixture effects on the rheological/mechanical behavior and micro-structure evolution of alkali-activated slag backfills
(MDPI, 2023)
Recently, alkali-activated slag (AAS) has attracted extensive attention in cemented paste backfill (CPB) due to its low cost/CO2 emissions and high strength benefits. However, a comprehensive analysis of the mechanical/rheological ...
Improvement of the durability of concrete by substitution of raw ground colemanite
(Elsevier, 2023)
This study investigated the effects of raw ground colemanite (GC) mineral on concrete strength and durability. Concrete mixtures were prepared at six replacement levels of GC (0%, 1%, 2%, 3%, 4% and 5%, by weight of cement). ...
Sill role effect on the flow characteristics (Experimental and Regression Model analytical)
(MDPI, 2023)
This study investigates the effects of gate openings and different sill widths on the sluice gate’s energy dissipation and discharge coefficient (Cd). The physical model of the sills includes rectangular sills of different ...
Polypropylene fiber effect on flexural strength, toughness, deflection, failure mode and microanalysis of cementitious backfills under three-point bending conditions
(MDPI, 2023)
Cemented tailings backfill (CTB) is continually practiced in a large number of metallic mines for re-filling underground ore extraction areas. Re-filling these areas can boost the security of mining teams during construction. ...
