More than one century after its massive introduction in the building industry, concrete is still most popular material. Nevertheless, several critical infrastructures show severe signs of distress. This fact fostered, recent years, need rethinking design process structures, view reducing maintenance costs and extending their service life. work has been performed framework H2020 project ReSHEALi...

Unfortunately, the production of cement impacts pessimistically on environments since it emits CO2—a principal Green House Gas (GHG)—encouraging earth-heating dilemma. Moreover, necessitates not only high temperature produced by devouring narrow natural mineral coal resources to obtain very amounts energy, but also gulps down limestone deposits as a raw material that is found confined in nature...

The use of sediments as supplementary cementitious material is increasing, but very limited information on their effect durability are available. aim this study to evaluate the and transport properties self-consolidating concrete (SCC) incorporating treated marine (TMS) dredged from Dunkirk harbor. Three SCC mixtures made with 0% (SCC-R), 10% (SCC-1), 20% (SCC-2) partial substitution cement wei...

Soil water infiltration is central to hydrologic studies and lends itself for detailed experimentation mathematical–physical modeling. The most rigorous of these approaches numerically solve Richards’ equation, possibly coupled through a heterogeneous soil surface routine groundwater model. This approach computationally expensive prone mass balance errors overparameterization. Analytic solution...

Wildfire can impact soil-hydraulic properties by reducing saturated hydraulic conductivity and sorptivity, making recently burned landscapes prone to debris flows flash floods. The post-fire hazard window range from years decades. In Northern California, where wildfire frequency is steadily increasing, the recovery wildfires unknown. Following October 2017 Nuns Tubbs fires in Bay Area of we est...

In Europe, about 55% of concrete bridges are 50 years old and require non-structural rapid repair strategies to reinstate the aesthetic durability performances. Existing focus primarily on superficial restoration that continues demonstrate premature deterioration due inevitable micro-crack formations further propagate macro-cracks leading ingress moisture along with harmful ions. this study, be...

Abstract Aims The surface crust formed by the drop impact of rainfall and/or irrigation is a prevalent characteristic in many Mediterranean soils. However, temporal variation soil hydraulic properties induced during high-frequency has rarely been investigated. Methods Beerkan infiltration tests conjunction with BEST method were used to investigate effects crusting on spatio-temporal saturated c...

Steel corrosion in reinforced concrete (RC) structures the marine environment is a major concern for engineers and asset managers. This paper presents an assessment of application deemed-to-satisfy durability design specification approach on newly constructed RC bridges Swakopmund-Walvis Bay Freeway upgrade Namibia, with desired service life at least 100 years. The comprised combination South A...

This study assesses the effect of mix design parameters on fresh and hardened properties, cost, carbon footprint geopolymer mortar made with desert dune fines (DDF) blast furnace slag (BFS). Taguchi method was employed in designing experiments. Four factors were considered, each having three levels, leading to a total nine mixes. The comprised DDF replacement percentage, alkali-activator soluti...
