Lab scale of charcoal compression strength: a new approach
(Associação Brasileira de MetalurgiaBelo Horizonte, 2014)
One of the main issues regarding the use of charcoal in metallurical processes is its mechanical strength, which is much lower than coke. There is no defined standard to determine charcoal compression strength, and the ...
High-Strength Concrete Masonry Walls under Concentric and Eccentric Loadings
(Asce-amer Soc Civil Engineers, 2018-06-01)
Masonry walls and columns are common structural members that typically resist compressive loads, with a number of such members being required to resist combined axial load and out-of-plane bending due to direct out-of-plane ...
INTRA-RING COMPRESSION STRENGTH OF LOW DENSITY HARDWOODS
(Universidad del Bío-Bío, 2006)
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 ...
Hardness and compressive strength of indirect composite resins: effects of immersion in distilled water
(Blackwell Publishing, 2004-11-01)
The aim of this study was to evaluate the effect of ageing in distilled water on the hardness and compressive strength of a direct composite resin Z100, a feldspatic porcelain (Noritake) and three indirect composites ...
Shear modulus G(0) and its correlations with matric suction, unconfined compression strength and tensile strength of an unsaturated residual soil
(Ios Press, 2015-01-01)
Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding ...
Influence of ultrasonic setting on compressive and diametral tensile strengths of glass ionomer cements
(ABM, ABC, ABPol, 2008)
The aim of this study was to assess the influence of ultrasonic wave propagation on the compressive (CS) and diametral tensile (DTS) strengths of glass ionomer cements (GICs). Three variables were evaluated: conventional ...
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 ...
Evolution of the mechanical properties of a tropical soil stabilized with lime and ash of rice rind
The ash of rice rind is a pozzolanic material that reacts with the calcium hydroxide (Ca (OH)2) forming bonding composites, when finely worn out and in water presence. Considering this behavior, the objective of the present ...
THE DENSITY, COMPRESSION STRENGTH AND SURFACE HARDNESS OF HEAT TREATED HORNBEAM (Carpinus betulus L.) WOOD
(Universidad del Bío-Bío, 2009)
