Testing High-Strength Concrete Compressive Strength

ACI Materials Journal, 1993
Comparative testing reveals that high strength concrete (HSC) compressive strength values are greater by 5% when measured on 100 x 200 mm specimens. Moreover, the coefficient of variation on one set of three 100 x 200 mm specimens is as small as, or smaller than that for 150 x 300 mm specimens.

The Dispersion of Concrete Compressive Strength of Existing Buildings

2014
The correct estimation of the compressive concrete strength plays a key role in the evaluation of the structural performance of existing RC buildings. Both Italian (NTC 2008) and European (EC8) Standards define different levels of knowledge according to the number of tests carried out on a building.

Compressive strength and modulus of elasticity of freshly compressed concrete

Construction and Building Materials, 2012
Abstract This paper is going to offer an interesting solution to enhance the compressive behavior of concrete in terms of strength and modulus of elasticity. In the presented method, by compressing the fresh concrete in a fabricated pressure apparatus, the excess water of concrete is expelled and the percent void is remarkably decreased.

Critical parameters for the compressive strength of high-strength concrete

Cement and Concrete Composites, 2017
Abstract This study investigates the influence of several material properties underlying the failure mechanism of high-strength concrete (HSC) under uniaxial compression. An experimental-numerical characterization of a single inclusion block (SIB) – an idealized composite comprising of a granite cylindrical core embedded within a high-strength mortar

Predicition of concrete compressive strength

2008
A compressive strength of concrete is considered as its basic material property. The conventional practice is that other mechanical and physical properties are brought into correlation with the compressive strength. Therefore, the prediction of compressive strength has always been of the greatest importance.

Neural prediction of concrete compressive strength

International Journal of Materials and Structural Integrity, 2018
In the past, a few researchers predicted the compressive strength of concrete from its ingredients by employing artificial neural network (ANN). Evaluation of the models with different performance metrics, such as correlation coefficient and errors of estimation, indicated that there was scope for improvement in the prediction performance of ANN.

Residual Compressive Strength of Heated Concrete

Architectural Science Review, 1993
Test results of a study designed to analyse the effect of elevated temperatures on the compressive strength of concrete incorporating factors such as water-cement ratio, aggregate-cement ratio, time of exposures are presented. It was shown that water-cement ratio is not a sensitive factor, while the hours of exposure to heat and the concrete mix are.
