Abstract: The durability of a concrete road to abrasive forces can be assessed effectively by measuring its abrasion resistance. This technical note reports the findings of a laboratory study including compressive strength, abrasion, ...

Abstract: In this work, the abrasion resistance of high volume fly ash concrete was investigated. Concrete mixtures containing a large amount of fly ash replacing the cement in mass basis at 50 and 70% were prepared with various ...

Abstract: In this work, a laboratory investigation was carried out to evaluate the strength and particularly the shrinkage properties of concrete containing high volumes of fly ash. The concrete mixtures made with 50 and 70% replacement ...

Abstract: The potential of a concrete for carbonation can be assessed effectively by measuring its carbonation depth using an accelerated carbonation testing. This paper reports the findings of a laboratory study including compressive ...

Abstract: igh-vertical-resolution rawinsondes were used to document the existence of low?bulk Richardson number (Rb) layers in tropical cyclones. The largest frequency of low Rb existed in the inner 200 km at the 13.5-km level. This ...

Abstract: Surface enlargement during bulk metal forming processes is one of the key parameters controlling the tribology at the tool-workpiece interface. Not only the surface roughness evolution but also the integrity of the lubricant ...

Abstract: Liquid water concentrations in cumulus clouds have been measured from an aircraft using the Johnson-Williams hot wire device. From simultaneous continuous cloud replicator records, liquid water contents have been computed ...

Abstract: Ice nuclei collected on Millipore filters were processed at ?16.6°C water saturation and resulting crystals allowed to sublime. The filters were then reprocessed. Eighty-three percent of the original sites reactivated, 17% ...

Abstract: Brush seals are one of the most effective sealing technologies in turbomachinery since they enable contact-type operation for close clearance control. Brush seal bristles must interact under turbine conditions, and the ...
