From the development of a mechanical device capable of performing the slump test of concrete, this work evaluated the equipment's ability to simulate the test recommended by norm. Slumps using the standard test and the ...

This work presents reliable empirical correlations of slump and spread measurements with yield stress of different materials based on the automated slump test methodology (capable of monitoring the transient regime of the ...

In order to mitigate mistakes, an automated slump test apparatus was developed for obtaining the slump measurement. Initially, tests involving eight different compositions of carbopol gel (used as a test material for ...

The current work shows the feasibility of using the mini-slump test to assesses the workability and rheological properties of MK-based geopolymeric pastes. The study aimed to define standard test procedures, including video ...

O ensaio de abatimento de tronco de cone, desenvolvido inicialmente como ferramenta de controle de qualidade para avaliar a consistência de materiais cimentícios e com grande aplicação no setor da construção civil, tem ...

Yield stress measurements were carried out on slurries prepared from five different ore samples of varying contents of bitumen and fines in the sand fraction. The rheological measurements were performed using the vane, ...

Mixing concrete is a standardized material whose consistency is measured by the slump, which has a previously defined acceptability range, but not always respected in the tacing water redosage by the mixer operator, causing ...

The Los Sombreros Formation represents the western continental margin slope deposits of the Argentine Precordillera, a sub-terrane accreted to Gondwana as part of the Cuyania Terrane in early Palaeozoic times. The age of ...

Evidence of earthquake-induced liquefaction features in the Acequión river valley, central western Argentina, is analysed. Well-preserved soft-sediment deformation structures are present in Late Pleistocene deposits; they ...
