SIZE EFFECT IN COMPRESSIVE STRENGTH OF CONCRETE
Transactions 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]
JES: 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
Journal 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.

Evaluation of the use of steelmaking slag as an aggregate in concrete mix: A factorial design approach [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2017 Slag is investigated towards its potential use as an aggregate in concrete mix production. Full factorial design methodology is applied to study the effect of two process input variables, namely: slag as coarse aggregate and slag as medium aggregate on ...

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

Analysis of the Optimum Usage of Slag for the Compressive Strength of Concrete [PDF]
Materials, 2015 Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength ...
