Empirical Models for Strength Characteristics of Concrete with Wood Ash Using Pebbles as Coarse Aggregates

ABUAD Journal of Engineering Research and Development
The determination of flexural and split tensile strengths of concrete is not commonly carried out on construction sites like compressive strength. However, not much research has been conducted on the correlation between flexural, splitting tensile and ...

Research Progress and Applications of Non‐Carrier‐Injection Electroluminescence

Advanced Electronic Materials, EarlyView.
Non‐carrier‐injection electroluminescence (NCI‐EL) uses AC fields and displacement currents to trigger light from internal charge reservoirs, enabling minimalist emitters with remotely coupled terminals. This review maps shared mechanisms across organics, GaN, quantum dots, and TMDCs, compares planar, interdigital, single‐terminal, and coaxial designs,

Effect on compressive strength of epoxy-modified mortar with further dry-curing [PDF]

, 2015
The percentage of concrete porosity will affects the strength and performance of the concrete. It is believed that, with an additional curing, the porosity of the concrete becomes lower and the strength will increase.

Effect of polyester fiber on compressive strength and split tensile strength properties of high strength concrete

Mehran University Research Journal of Engineering and Technology
High strength concrete (HSC) is essential for large-scale projects, such as bridges, dams, and high-rise buildings, as it allows for reduced dimensions of beams and columns. This experimental study investigates the effect of polyester fiber on the compressive and split tensile strength properties of HSC grade C60.
