Determination of in situ uniaxial compressive strength of coal seams based on geophysical data
(SPRINGER HEIDELBERG, 2009)
The central issue for pillar design in underground coal mining is the in situ uniaxial compressive strength (sigma (cm)). The paper proposes a new method for estimating in situ uniaxial compressive strength in coal seams ...
Experimental investigation on the use of steel-concrete bond tests for estimating axial compressive strength of concrete: part 1
(IBRACON - Instituto Brasileiro do Concreto, 2013-10)
This study analyzes the feasibility of using steel-concrete bond tests for determining the compressive strength of concrete in order to use it as a complement in the quality control of reinforced concrete. Lorrain and ...
Evaluation of the long-term compressive strength development of the sewage sludge ash/metakaolin–based geopolymer
(2021-07-28)
This paper aimed to evaluate the long-term compressive strength development of the sewage sludge ash/metakaolin (SSA/MK)–based geopolymer. SSA/MK–based geopolymeric mortars and pastes were produced at 25ºC with different ...
Numerical and experimental preliminary study of temperature distribution in an electric resistance tube furnace for hot compression tests
(Universidad Nacional de Colombia Sede Medellín, 2014-08-26)
Hot compression tests are performed when jaws, each one with a jacketed section to cool a part of its length, move through a tube furnace at elevated temperatures to compress a metal sample between them, changing the ...
On the compressive strength prediction for concrete masonry prisms
(SPRINGER, 2010)
The results of a combined experimental program and numerical modeling program to evaluate the behavior of ungrouted hollow concrete blocks prisms under uniaxial compression are addressed. In the numerical program, three ...
Compressing arrays of classifiers using Volterra-Neural Network: application to face recognition
(Springer, 2013-07)
Model compression is required when large models are used, for example, for a classification task, but there are transmission, space, time or computing constraints that have to be fulfilled. Multilayer Perceptron (MLP) ...
Prediction of modulus of elasticity and compressive strength of concrete specimens by means of artificial neural networks
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacao, 2016-01-01)
Currently, artificial neural networks are being widely used in various fields of science and engineering. Neural networks have the ability to learn through experience and existing examples, and then generate solutions and ...
Experimental study of reinforced masonry beams
(IBRACON - Instituto Brasileiro do Concreto, 2019-11-11)
An experimental program on reinforced concrete masonry beams was conducted aiming to better understand the behavior of reinforced masonry beams. The beams were designed to fail in flexure, assessing cracking patterns, ...
Influence of compression forces on tablets disintegration by AC Biosusceptometry
(Elsevier B.V., 2008-05-01)
Analysis of physical phenomena that occurs during tablet disintegration has been studied by several experimental approaches; however none of them satisfactorily describe this process. The aim of this study was to investigate ...
Influence of the addition of “synthetic termite saliva” in the compressive strength and water absorption of compacted soil-cement
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2016)
