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 ...
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 ...
Effect of milling process for rice husk ash on mechanical strength of blended Portland cement mortars
Nowadays, the reuse of waste products in the construction process is a priority research area. Several industrial and agricultural waste products have been investigated, such as fly ash, sugar cane bagasse ash and rice ...
Spent FCC catalyst for preparing alkali-activated binders: An opportunity for a high-degree valorizatio
Spent FCC catalyst is a waste from the petrochemical industry which has excellent pozzolanic properties, containing more than 90% silica and alumina. Its similarity to metakaolin creates interesting prospects for its use ...
Effect of SiO2 on compressive strength and hot abrasion resistance of self-reducing pellets bonded with Portland cement
Effects of electroplated zinc-nickel alloy coatings on the fatigue strength of AISI 4340 high strength steel
It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...
Unsaturated polyester based composites reinforced with curauá fiber - Preliminary studies
Curauá fiber processing characterization has been performed throughout the different processing steps. Unsaturated polyester has been used as matrix in the production of curauá reinforced composite samples. Compression ...
Plasma immersion ion implantation on 15-5PH stainless steel: Influence on fatigue strength and wear resistance
Surface improvement in steels is of great interest for applications in industry. The aim of this investigation is to study the effect of nitrogen ion implantation on the axial fatigue strength and wear resistance of 15-5 ...
Application of UTHSCSA-Image ToolTM to estimate concrete texture
The texture of concrete blocks is very important and is often the decisive factor when choosing a product, particularly if the building specifications does not dispense with the high resistance of the blocks, but has the ...
