The sustainable utilization of post-consumer waste glass in concrete has emerged as a promising approach to reduce cement consumption, mitigate landfill disposal, and enhance material performance. However, most previous ...

Glass ionomer cement as one of the restoration materials requires high compressive strength so it can last during functional activity. The latest glass ionomer cement comes with glass hybrid technology and a nanofilled r...

Abstract Background Dental plaster, dental stone, and improved stone are commonly used gypsum products for dental molds. While improved stone is preferred for final molds due to its strength, dental plaster is cheaper bu...

Abstract Accurate prediction of compressive strength is important for the efficient design of sustainable concrete incorporating palm oil fuel ash (POFA). This study developed a hybrid artificial neural network model opt...

Abstract The Broad Learning System (BLS) provides an effective framework for nonlinear mapping, offering advantages over traditional deep neural networks through its expanded input node architecture. While BLS has demons...

Oil palm empty fruit bunch (OPEFB) fibers have emerged as a promising natural alternative to synthetic fibers due to their mechanical strength and biocompatibility, although research on their use as a reinforcing in comp...

The present study focuses on proposing various statistical models, such as linear regression (LR), nonlinear regression (NLR), and artificial neural network (ANN), to forecast the compressive strength of environmentally ...

Abstract This research employs hybrid machine learning techniques to optimize the mechanical properties of 3D-printed polylactic acid (PLA) lattice structures. By integrating random forest (RF) and XGBoost (XGB) algorith...

Abstract Metamaterials are defined as artificially designed micro-architectures with unusual physical properties, including optical, electromagnetic, mechanical, and thermal characteristics. This study investigates the c...

Abstract The development of sustainable infrastructure in Nigeria requires the effective use of native timber species in designed constructions. This study assesses the structural integrity of glue-laminated timber (Glul...

Red mud that is produced as a residue of alumina from bauxite ore through the Bayer process is undesirable or has potential environmental problems due to its large volume and high pH. Red mud was incorporated into the co...

Abstract This work developed an enhanced model to examine the High-Strength Fiber-Reinforced Concrete (HSFRC) that is replaced with 10% metakaolin as a sustainable cement replacement and four types of fibers at different...

The experimental tests are carried out on the strength and deformation characteristics of four typical rock samples of phyllite taken from the northern tunnels of Longmen Mountains of the Chengdou-Lanzhou Railway. The re...

To illustrate the variation laws of strength characteristics and micromechanism of rubber-sand mixtures, a series of laboratory tests including direct shear tests, unconfined compressive strength tests and scanning elect...

Abstract Utilization of industrial waste to produce geopolymer concrete is a good answer to minimize the carbon-dioxide( Co2) released from the traditional procedure of producing Ordinary Portland cement (OPC). This not ...

Transverse reinforcement with welded meshes is used in areas of significant compressive forces, usually in local places, where it is necessary to increase the strength of concrete in axial compression. In a calculated wa...

A crucial objective for mitigating the global environmental footprint of the construction sector is the imperative to develop sustainable and ecological concrete alternatives. This investigation presents a novel strategy...

Waste material, including glass, presents significant environmental challenges due to its non-biodegradable nature and low global recycling rates. Incorporating waste glass into concrete offers a sustainable solution, bu...

Аn analysis of the structure formation of concrete composites, compressive strength of which exceeds 120 MPa and a quantitative analysis of their qualitative composition and hydration products by X-ray diffraction, x-ra...
