Abstract: Concrete is one of the key component in the construction field. The importance of concrete is because of its strength and long lasting properties. The incorporation of nano materials in concrete helps to improve the characteristics of conventional concrete. Titanium dioxide (TiO2) is one such nanomaterial that helps to increase the performance of concrete by enhancing self-cleaning, anti-microbial and anti-bacterial activities. This paper... More

Abstract: The present study aims to analyzse alternative passive design solutions for enhancing building energy and hygrothermal efficiency in the Sahelian zone. To achieve this, a model representing a standard single-storey cement-hollow block dwelling building and its relevant parameters was input into EnergyPlus, combined with OpenStudio or SketchUp. Scenarios were then analyzed to evaluate the effects of roof solar reflectivity, wall external... More

Abstract: In order to improve the damage resistance of concrete, a cement-based self-healing additive (abbreviate as CS) was prepared. To investigate the influence of CS on the self-healing performance of cementitious material, X-ray diffraction (XRD) and thermal analysis were used to investigate the effects of different dosages of CS on the hydration process and hydration products of cementitious material. Compressive strength test and load damage... More

Abstract: Crystalline admixtures (CA), also known as permeability reducer admixtures, are used in binder-based materials to improve concrete durability by reducing water permeability depth, increasing compressive strength, and stimulating crack healing. The purpose of this study is to evaluate the potential of crystalline admixtures to enhance the self-healing characteristics and durability attributes of concrete and to contribute to the understanding of...

Abstract: Evaluating the performance of existing concrete structures is essential in civil engineering, with compressive strength serving as an indicator of performance. Non-destructive testing (NDT) techniques are commonly employed due to their cost-effectiveness and the ability to assess structural integrity without causing damage. However, NDT methods often yield less accurate results than destructive testing (DT), which, although highly reliable, is... More

Abstract: Geopolymer composites are remarkable binding materials due to their sustainability and recyclability. This study investigates the behaviour of Self-Compacting Geopolymer Concrete (SCGC) as a viable alternative to conventional concrete. It examines the effects of adding Lightweight Coarse Aggregate (LWCA) and Steel Fibre (SF) under different curing environments on the fresh and hardened properties of SCGC. Curing was applied using microwave and... More

Abstract: The rapid emergence of the Internet of Things (IoT), immersive technologies, and spatial devices is transforming architecture by changing the built environment from a passive backdrop to an active participant in user activities. This shift creates complex sociotechnical networks and leads to what we call intelligent places adaptive systems that respond to user behavior, environmental signals, and interactions with architectural components. This... More

Abstract: Materials used in building envelopes and urban areas contribute significantly to the urban heat island (UHI). In this context, this paper presents a study utilizing infrared thermography (IRT) to assess urban streets and building surface materials in the coastal city of Bayahibe, Dominican Republic. Measurements were conducted in situ in six urban street canyons (Sections A–F) during the warmest and coldest weather conditions. A FLIR T420... More

Abstract: This study investigates the influence of date palm fibers (DPF) on the mechanical performance of bituminous mixtures using two experimental methodologies: the wet and dry processes. In the wet process, DPFs were pre-blended with bitumen at varying contents ranging from 1% to 5% by weight, prior to mixing with aggregates. The resulting mixtures were evaluated based on several key performance indicators, including Marshall stability, creep... More

Abstract: The rapid growth of the global population, coupled with increasing pollution levels, highlights the urgent need for sustainable and eco-friendly construction materials, such as unfired clay bricks. However, their widespread adoption remains limited due to certain performance drawbacks, particularly in thermal insulation, a critical factor in addressing climate change challenges. In this study, a plant-based waste-derived biopolymer was... More

Abstract: This work quantifies the thermal performance of natural composite blocks made from Yapatera diatomaceous earth reinforced with sugarcane bagasse fibres. Prismatic specimens (185 × 185 mm) with three thicknesses (≈76 mm, 100 mm, and 150 mm) and bagasse contents of 5–15% (wt.) were tested at hot-face temperatures of 100, 250, and 450 °C in a full-factorial 3 × 3 × 3 plan (54 tests). Thermal conductivity (k) was measured using a guarded hot-plate... More

Abstract: The uptake of biochar from sewage sludge has developed into a critical avenue for resource reclamation whilst solving waste disposal concerns. However, despite the latter side in environmental palliative, the use of this biochar for remediation, recovery of nutrients, or adsorption of pollutants is often suboptimal due to poor surface area, high percentage of ash and functional group scarcity. Sewage sludge-derived biochar (SSB) has emerged as a... More

Abstract: This paper introduces a thermodynamically grounded framework that replaces conventional energy-centric building simulation with a heat-based reconstruction method, enabling the use of standard-year weather data without bespoke weather files. High-accuracy predictive models are developed to estimate seasonal heating and cooling loads and to derive convective heat transfer coefficients for transitional seasons. Models are calibrated against... More

Abstract: Decorative construction typically accounts for 20–50% of total project costs. China introduces energy-saving panels, primarily composed of sand particles, to reduce its energy consumption. Most importantly, it has the ability to efficiently resolve intricate acoustic issues with remarkable speed and convenience. This study focuses on sand-based energy-saving panels, which efficiently address complex acoustic issues while reducing energy... More
