Structural Concrete, EarlyView.Abstract Cellulose nanocrystals (CNCs), increasingly utilized in cement‐bound materials, offer improved material properties and enhanced sustainability due to their bio‐based origin. Nanosilica (NS), known for its high reactivity and refinement of cement microstructure, also significantly impacts cement performance.

Hydration of the combinations of ground granulated blast furnace slag cements [PDF]
, 2014 The heat of hydration is known as a measurement of the initial chemical reactions for the hydration of cement. The heat liberated during the hydration process affects the temperature rise in concrete, which may cause an early-age thermal cracking of a ...

Structural Concrete, EarlyView.Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...

Structural Concrete, EarlyView.Abstract Fly ash foam composite concrete (FFC) is a sustainable, lightweight alternative to traditional concrete. However, accurately predicting its compressive strength (CS) through conventional laboratory methods is challenging due to its non‐linear behavior induced by the addition of foam content and fly ash. Also, the laboratory determination of CS

Structural Concrete, EarlyView.Abstract The field of reinforced concrete (RC) strengthening continues to evolve as the construction industry seeks cost‐effective and sustainable alternatives to structural replacement. This study, therefore, aimed to comprehensively investigate the pioneering application of steel‐reinforced grout (SRG) for strengthening large‐scale, 3.5‐meter‐long ...
