Mechanical Performance and Embodied Energy Assessment of Geopolymer-Stabilized Earthen Masonry Blocks Incorporating Gold Mine Tailings and Tank Bed Soil

Due to its contributions to the emission of greenhouse gases, the depletion of topsoil, and the consumption of non-renewable energy resources, the fired clay brick industry is under considerable scrutiny. The investigation of unfired Geopolymer-Stabilized Earthen Bricks (GSEBs) with binder matrices comprised of Class F...

Multi-Objective Optimization of GGBS Blended Pervious Concrete: Coupling Mechanical Strength, Permeability, and Water Purification via Microstructure Control

This study extends the design space of pervious concrete with respect to strength, drainage, and water purification using a multi-objective optimization approach. GGBS was used as a partial cement replacement (15–45%) across four no-fines coarse-aggregate gradations and assessed for compressive strength (accelerated, 7...

Flexural Performance of Reinforced Concrete Beams Incorporating Cement-Bonded Fly Ash Aggregates as Partial Replacement of Natural Coarse Aggregate: Experimental Investigation, ANN Modelling, and Durability Assessment

The rising demand for natural coarse aggregate and its consequences have necessitated investigations into alternative aggregates from industrial sources. The structural performance and durability of reinforced concrete beams with cement-bonded Fly Ash Aggregate (FAA) at 25%, 50%, 75%, and 100% of the volume of natural...

Experimental Investigation and ML Based Prediction of Compressive Strength of Concrete with Substitution of Coarse Aggregates by Agro-Waste under Wax and Water Curing Regimes

The rapid urbanisation of the Earth’s inhabited continents has led to the depletion of the planet’s natural aggregate reserves. In response, scientists and engineers have begun to seek out alternative construction materials that are both sustainable and capable of maintaining the structural integrity of constructed bui...

A Unified Digital Twin Framework for Autonomous Lifecycle Management of Civil Infrastructure: Integrating Cyber–Physical Systems, AI-Driven Predictive Analytics, and Real-Time Optimization

A unified DT framework that couples a cyber-physical sensing and communication layer, an entropy-weighted multi-sensor fusion scheme, a hybrid physics-plus-machine-learning surrogate, extended Kalman assimilation for continuous model updating, and a constrained multi-objective optimisation layer that closes the loop fr...

Experimental investigation of the mechanical and durability performance of hybrid basalt fiber-reinforced concrete using gaussian process regression-based prediction
