Flexural behavior of corroded RC beams repaired with high performance cementitious mortar under cyclic loading

Structural Concrete, EarlyView.
Abstract The understanding of the cyclic performance of reinforced concrete (RC) elements is of vital importance in relation to the extent of the service life of buildings and infrastructures. Steel rebar corrosion plays a major role in this regard because it significantly affects the overall structural integrity, especially under cyclic loads, leading

Durability and compressive strength of blast furnace slag-based cement grout for special geotechnical applications

Materiales de Construccion, 2014
Special foundations, most prominently micropiles and soil anchors, are frequently used in construction today. In Spain, the grout for these special technical applications is generally prepared with portland cement, although the codes and standards in ...

Development of a full-Scale approach to predict overlay reflective crack [PDF]

International Journal of Pavement Engineering, 25(1), 2310095 (2024)
Resurfacing a moderately deteriorated Portland cement concrete (PCC) pavement with asphalt concrete (AC) layers is considered an efficient rehabilitation practice. However, reflective cracks may develop shortly after resurfacing because of discontinuities (e.g. joints and cracks) in existing PCC pavement.

Residual textile reinforced mortar‐to‐concrete bond after exposure to harsh environments

Structural Concrete, EarlyView.
Abstract Textile reinforced mortars (TRM) are materials whose mechanical behavior has been extensively investigated during the last few years. However, studies on the behavior of these materials after exposure to various aggressive environments are still limited and, hence, their performance during their entire service life remains to be determined ...

Structural behavior of deteriorated Gerber half‐joints in highway overpasses by nonlinear finite element analysis combined with a simplified uniform‐corrosion model

Structural Concrete, EarlyView.
Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...

Silica-coated admixtures of bismuth and gadolinium oxides for 3D printed concrete applications: Rheology, hydration, strength, microstructure, and radiation shielding perspective [PDF]

Construction and Building Materials, Volume 470, 4 April 2025, 140563
This study examines the impact of replacing up to 5 vol% of Portland cement (PC) with both pristine Bi2O3/Gd2O3 (BG) and silica-coated BG particles. Two different types of silica coatings, each with varying synthesis methods, were applied to coat the BG structures, and their impact on the fresh, hardened, microstructure and radiation-shielding ...

Alkali-Activated Cement-Based Binders (AACBs) as durable and cost-competitive low-CO2 binder materials: some shortcomings that need to be adressed [PDF]

, 2017
Available online 14 October 2016.The production of 1 t of ordinary Portland cement generates 0.55 t of chemical CO2 and requires an additional 0.39 t of CO2 in fuel emissions for baking and grinding, accounting for a total of 0.94 t of CO2.

Data informed performance assessment and structural health monitoring for existing and historical concrete structures

Structural Concrete, EarlyView.
Abstract Our generation inherits this cultural heritage of historic material and historic reinforced concrete structures and thus bears a certain responsibility to preserve these historic buildings with the help of the new technologies of lifetime management, conservation concepts and the new digitalization as well as the emerging safety concepts of ...
