Discrete studies are performed on the reuse of end-of-life tires in the construction industry as their accumulation is a global concern to the environment. In consequence, the desired focus of this work is to understand the interaction of powder derived from recycling process of tire waste which yet...
Solid Waste Management
Natural gravel used as aggregates in the construction had a severe impact on the environment leading to scarcity in recent times. Furthermore, the resistance of such natural aggregates to crack at higher temperature zones was less. This paper investigates the above concerns on scarcity and meagre...
Solid Waste Management
Dumping of construction wastes has become one of the serious concerns in the construction industries subsequent to the scarcity of construction materials, specifically aggregates. Extensive research works have been performed to utilize the dumped waste as aggregates, yet its substandard properties...
Solid Waste Management
A Squeeze and Excitation Network is a deep-learning architectural component designed to enhance networks. The "squeeze" step reduces the spatial dimensions of the input feature maps, and the "excitation" step adaptively recalibrates channel-wise feature responses. This allows the network to focus on...
Water and Wastewater Treatment
Cyanide compounds are widely used in some electroplating, chemical and metallurgical industries. They are often found in their liquid discharges. This work highlights the performance of an activated alumina-supported copper catalyst in the removal of cyanide by oxidation with hydrogen peroxide in...
Solid Waste Management
Industrial by-products such as cementitious materials or aggregates have the potential to mitigate the adverse environmental effects associated with traditional cement manufacture. Geopolymer Concrete (GPC) is more eco-friendly than conventional concrete because it does not require cement. GPC with...
Solid Waste Management
As an important resource for the IT sector and due to the extremely hazardous elements it contains and the low recycling rate, e-plastic waste management and recycling are growing swiftly. E-plastic waste utilization reduces aggregate costs, landfill costs and energy prices. Rapid population growth...
Solid Waste Management
Excessive consumption of natural resources for concrete production results in the diminution of conventional resources, leading to the scarcity of construction materials. Perhaps, the dumping of construction wastes increases the municipal wastes ensuing in disposal problems. The dumped construction...
