1. Rutting analysis of 100 mm diameter polypropylene modified asphalt specimens using gyratory and Marshall compactors
Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a more realistic way of simulating actual compaction. In this study, mechanical differences of reference and polypropylene modified asphalt

2. Método de dosagem de concreto pelo volume de pasta com emprego de cinza volante / Concrete mix-proportioning method by cement paste volume using fly ash
This study was developed in order to create and a streamlined methodology of concrete mix proportioning using fly ash to reduce the cement content and an intensive use of a pollutant contributing to the increase of sustainability in construction through reducing consumption of clínquer and the release of carbono dioxide to the atmosphere. It was established

3. Estudo comparativo de métodos de dosagem de concretos de cimento Portland / Comparative study of mix-proportioning methods of Portland cement concrete
O presente trabalho tem como objetivo fundamental realizar um estudo comparativo de cinco métodos de dosagem de concretos de cimento Portland, alguns deles, de grande divulgação e uso no Brasil. Os cinco métodos estudados, designados como ABCP/ACI, EPUSP/IPT, INT/Lobo Carneiro, ITERS/Petrucci e SNCF/Vallette, são apresentados inicialmente através dos s

4. Estudo do comportamento do concreto no estado fresco contendo areia britada
The crushed sand possesses different characteristics from the natural one, mainly due to the high fine materials contents, particle size distribution, shape, roughness and lithological types. It is formed during the process of comminution of rock, and its able to suffer classification and improvement of the particles shape. Such characteristics affect, in la

5. Os compostos do clínquer Portland: sua caracterização por difração de raios-X e quantificação por refinamento de Rietveld. / Portland clinker phases: their characterization by X-ray diffraction and quantification by Rietveld refinement.
The project has focused on the application of X-ray diffraction (XRD) on the characterization and quantification of the Portland cement clinker crystalline compounds using the Rietveld method. The present research represents a pioneer scientific contribution on the theme in Brazil. Overall forty clinker samples from five distinct kiln lines were collected fo
