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

Materials 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

Frontiers 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

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

Jurnal 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

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
