Evaluation of the relationship between strength, quality grade, microstructure and abrasion of concrete

open access: yesMaterials Research Express, 2021
Surface abrasion is the most general cause of concrete deterioration. Abrasion can be a catalyst for structural failures, as abrasion leads to structural cracks and reinforcement corrosion.

Multiaxial compressive strength of hybrid fiber reinforced concrete: A unified empirical model

open access: yesFrontiers in Materials, 2023
In engineering design, the strength analysis of concrete structures heavily depends on the compressive strength of hybrid fiber reinforced concrete (HFRC), which also has an impact on the stability and safety of the structure. The objective of this study

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

THE UTILIZATION OF CONCRETE WASTE AS AN AGGREGATE SUBSTITUTE AND THE ADDITION OF DENIM FABRIC FIBERS ON COMPRESSIVE AND FLEXURAL STRENGTH OF CONCRETE

open access: yesJurnal Pensil
Concrete is one of the construction materials used in building structures, bridges, roads, and others. The material components that make up concrete consist of fine aggregates (sand), coarse aggregates (gravel), water, and cement. However, the drawbacks
