Abstract: This study investigates the impact of bedding plane orientation on sodium chloride (NaCl) precipitation in a calcarenite stone, subjected to salt weathering cycles. It involves conducting wetting-drying cycles using sodium chloride on two series of specimens sampled parallel and perpendicular to the bedding plane. Capillary imbibition was carried out using saline solutions of two concentrations (15 g/L and 45 g/L). SEM observations show that,... More

Abstract: Fiber reinforcement significantly enhances the strength, toughness, and durability of concrete by reducing the propagation of microcracks in the concrete matrix. With the rising demand for high-performance concrete (HPC), this study investigates the mechanical properties of HPC with varying proportions of polypropylene (PP) and steel (ST) fibers. Supplementary cementitious materials (SCMs) toward partial replacement of ordinary Portland cement... More

Abstract: Concrete creep, which is characterised by the gradual, time-dependent deformation under sustained loading, remains a critical factor for structural durability, safety and long-term performance. This review synthesises key advancements in creep research, tracing its evolution from early foundational experimental studies and empirical models such as Bažant’s B3 to contemporary materials innovations and emerging computational frameworks. Novel... More

Abstract: Concrete blocks are widely used for wall construction in Thailand, and reliable Carbon Footprint of Product (CFP) data for these blocks is essential for accurately estimating the embodied carbon of buildings—a crucial consideration in sustainable building design. This research evaluates the CFP of concrete blocks produced by a Thai factory, using a functional unit of one ton. The assessment applies a "Cradle to Gate" approach, covering both raw... More

Abstract: This study evaluates the influence of sand content on the mechanical behavior and water resistance of compressed earth bricks (CEBs) manufactured from Lendi clay (Douala, Cameroon). Twenty-seven specimens (prismatic and cubic) were produced with three formulations: 0%, 30% and 60% sand substitution by dry mass, compacted at 2.5 MPa and cured for 7, 14 and 28 days. Raw material characterization included particle size distribution, sand... More

Abstract: The movement of interacting faults within the Earth's crust during earthquakes may cause significant structural damage. Large earthquake fault surfaces are often planar or a combination of several planar fault segments. This study analyses the interaction between a non-planar and a planar fault, where the faults are inclined, buried, creeping and strike-slip in nature. The non-planar fault is infinite and formed by two interconnected planar... More

Abstract: This study explores the novel application of Triumfetta pentandra (TP, “Nkui”) fibers, a tropical plant that is abundant yet underutilized in civil engineering, to enhance the performance of compressed earth bricks (CEBs). The main objective is to assess how incorporating these vegetal fibers can improve the mechanical properties of CEBs while maintaining durability. TP fibers were extracted, characterized, and integrated into the soil used for... More

Abstract: Reactive Powder Concrete (RPC) is an advanced construction material prized for its superior strength and durability. However, its dense, ultra-low porosity microstructure, while beneficial for mechanical properties, renders it highly susceptible to explosive spalling when exposed to temperatures between 200 °C and 400 °C. This dangerous phenomenon occurs as trapped moisture and air within the RPC’s pores rapidly expand upon heating, generating... More

Abstract: The rapid change in CO2 concentration levels, due to climate change, will lead to a significant reduction in the durability and safety of the vital reinforced concrete (RC) structures. Utilizing supplementary cementitious materials, such as low calcium fly ash (LCFA) or slag, etc., with larger percentages in concrete mixes, would lead to an increase in the carbonation depth and risk of corrosion, especially for cracked concrete sections...

Abstract: The transition toward low-carbon concrete (LCC) represents a critical pathway for decarbonizing the construction sector and achieving global net-zero targets. This study provides a comprehensive and analytical review of material innovations, digital enablers, and policy mechanisms shaping the evolution of LCC technologies. A systematic PRISMA-based review combined with bibliometric mapping (VOS viewer) was conducted across various peer-reviewed... More

Abstract: Sustainable development has emerged as a defining priority in contemporary urban planning, with increasing emphasis on minimizing environmental impacts while promoting efficient resource use and long-term resilience. Among the globally recognized frameworks supporting this transition, the Leadership in Energy and Environmental Design (LEED) certification system has become a key benchmark for evaluating environmentally responsible construction...
