Determination of the bilinear stress‐crack opening curve for normal‐ and high‐strength concrete [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2008 ABSTRACTAn improved version of the method proposed to ACI committee 446 and to RILEM TC 187‐SOC to determine the fracture parameters of concrete is applied in this study to several mixtures of normal and high‐strength concretes. The results are processed with a C++ program developed by the authors to automatise the mathematical operations required to ...

Effect of aggregates on the compressive strength and permeability of concrete [PDF]
مهندسی عمران شریف, 2022 Aggregates make up between 60% and 80% of the concrete volume, being surrounded by the cement paste and their properties all have significant impact on the behavior of concrete, during the service life for which it been designed.

Mechanical properties of lightweight concrete with sintered aggregate [PDF]
MATEC Web of Conferences, 2020 The objective of this paper is the determination of short-term properties of lightweight concrete with sintered aggregate. The aggregate material comes from the recycling of ashes from power plants, which yield granules after processing. The research was

Study of the strength properties of modified concrete in tension [PDF]
E3S Web of Conferences, 2023 The resistance of concrete to axial tension is much less than the resistance to compression and is largely determined by the adhesion of its components. The low tensile strength of ordinary concrete is explained by the heterogeneity of its structure and ...
