Influence of Inertia on the Dynamic Compressive Strength of Concrete

open access: yesMaterials, 2022
The rate sensitivity of concrete material is closely related to the inertia and viscous effects. However, the effect of inertia on the dynamic strength of concrete remains unclear. In this paper, digital image correlation technology was applied to study the strain variation of dry and saturated concrete with different loading rates.

SIZE EFFECT IN COMPRESSIVE STRENGTH OF CONCRETE

open access: yesTransactions of the Architectural Institute of Japan, 1977
Abstract Three series of experiments were carried out to examine the effect of the size and type of aggregate on the size effect in the compressive strength of concrete from the standpoint that it may result from the geometrical heterogeneity of concrete system.

USES OF DRY VINASSE AS A FRIENDLY ENVIRONMENTAL MATERIAL TO IMPROVE PROPERTIES OF CEMENT MORTAR AND CONCRETE [PDF]

open access: yesJES: Journal of Engineering Sciences, 2020
This study aims at using the sugar by-product (dry vinasse), as one of the concrete production requirements, instead of getting rid of them in vain. Dry vinasse was obtained by drying liquid vinasse at 250 ° C.

Relationship between compressive and tensile strengths of roller-compacted concrete

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The abstract roller-compacted concrete (RCC) is a zero slump concrete comprising the same materials as that of conventional concrete with different proportions. The RCC must be compacted to reach its final form.

ANN-Based Fatigue Strength of Concrete under Compression [PDF]

open access: yesMaterials, 2019
When concrete is subjected to cycles of compression, its strength is lower than the statically determined concrete compressive strength. This reduction is typically expressed as a function of the number of cycles. In this work, we study the reduced capacity as a function of a given number of cycles by means of artificial neural networks.
