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.

Using Epoxy Resin as Partial Cement Replacement in Concrete with Silica Sand as Fine Aggregate
Civil engineering and architecture, 2021 Plain concrete has low tensile strength, therefore, it is reinforced with steel for structural use. Both the production of concrete and the manufacture of steel adversely affect the environment.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review
Journal of Field Robotics, EarlyView.ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Structural Concrete, EarlyView.Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Evaluation of in-situ shrinkage and expansion properties of polymer composite materials for adhesive anchor systems by a novel approach based on digital image correlation [PDF]
, 2019 The curing reaction of thermosetting resins is associated with chemical shrinkage which is overlapped with thermal expansion as a result of the exothermal enthalpy. Final material properties of the polymer are determined by this critical process.

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin
Structural Concrete, EarlyView.Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.
