Rheological effects of commercial waxes and polyphosphoric acid in bitumen 160/220--high and medium temperature performance.
October 1, 2007... The effects of adding three commercial waxes and a polyphosphoric acid to three bitumens of 160/220 penetration grade were studied using different types of laboratory equipment, such as Dynamic Shear Rheometer (DSR), Differential Scanning...

Estimates of self-compacting concrete 'potential' durability.
October 1, 2007... Abstract The building industry is progressively trying to use self-compacting concrete (SCC) in order to improve many aspects of construction, principally reinforced concrete. However, the problem of its durability still exists,...

Fatigue behaviour of recycled tyre rubber-filled concrete and its implications in the design of rigid pavements.
October 1, 2007... Abstract This paper presents the results of fatigue bending tests on prismatic samples of recycled tyre rubber-filled concrete (RRFC) with different volumetric fractions (VF) of rubber (0%, 3.5% and 5%) after a long term exposition to...

Optimization on proportion for recycled aggregate in concrete using two-stage mixing approach.
October 1, 2007... Abstract Recycled aggregate (RA) is well acknowledged having a poorer quality due to its higher porosity resulted from cement mortar remains attaching to its surface that hampers the recycling rate of concrete waste. Many previous...

Debonding of FRP in bending: simplified model and experimental validation.(fiber-reinforced polymer)
October 1, 2007... Abstract Reinforced concrete members strengthened in bending by bonding of surface-mounted fiber-reinforced polymer (FRP) may present several failure modes: failure of material (reinforcing steel, concrete and composite material) or...

The use of the powder marble by-product to enhance the properties of brick ceramic.
October 1, 2007... Abstract In general, the ornamental stone industries have as by-product a fine rock powder that might be suitable to be used in civil engineering construction purposes. Therefore, this work intends to discuss some technical aspects...
