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 ...
Predicting long-term impact of cementitious mine fill considering sand as a copper-tailings substitution
(Elsevier, 2023)
It is of great importance to use different materials or techniques to enhance the quality/behavior of cementitious mine fill (CMF). This leads the mining industry to evaluate new production techniques or resources that ...
A novel framework for strength prediction of geopolymer mortar: Renovative precursor effect
(Elsevier, 2023)
Concrete is the most used building material today as it has many advantages due to its structure. Geopolymer composites could potentially replace concrete in the future due to the demands of the construction industry. The ...
Accuracy improvement in Ag:a-Si memristive synaptic device-based neural network through Adadelta learning method on handwritten-digit recognition
(Springer, 2023)
Traditional computing architecture (Von Neumann) that requires data transfer between the off-chip memory and processor consumes a large amount of energy when running machine learning (ML) models. Memristive synaptic devices ...
Solar salt with carbon nanotubes as a potential phase change material for high-temperature applications: Investigations on thermal properties and chemical stability
(American Chemical Society, 2023)
Nano-enhanced phase change materials are highly employed for an enhanced heat-transfer process. The current work reports that the thermal properties of solar salt-based phase change materials were enhanced with carbon ...
