Types and Causes of Concrete Deterioration

concrete, the passive corrosion rate is typically 0.1 µm per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher (ACI 222 2001). Because of concrete’s inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures.

Discrete Element Modeling of Asphalt Concrete: Microfabric ...

A microfabric discrete element modeling (MDEM) approach is presented for modeling asphalt concrete microstructure. The technique is a straightforward extension of a traditional discrete element modeling (DEM) analysis, in which various material phases (e.g., aggregates, mastic) are modeled with clusters of very small, discrete elements.

Sustainable Precast Concrete

Precast concrete structures are usually lighter than the equivalent area of on-site cast-in-place concrete. This can represent a significant reduction in the number of truck movements and reduced consumption of fossil fuels. The amount of energy consumed during the transport of precast elements is about 0.00114 MJ/kg/km.
