We consider applications, illustration and concrete numerical treatments of some homogenization results on Stokes flow in porous media. In particular, we compute the global permeability tensor corresponding to an unidirectional array of circular fibers for several volume-fractions. A 3-dimensional problem is also considered.
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Structural health monitoring of porous materials such as concrete is becoming a major component in our resource-limited economy, as it conditions durable exploitation of existing facilities. Durability in porous materials depends on nanoscale features which need to be monitored in situ with nanometric resolution. To address this problem, we put forward an approach based on the development of a ...
Porous concrete can be used as a drainage system that allows rainfall to percolate into the ground, reduce stormwater runoff, and recharge groundwater. consists of coarse aggregate cement paste. Stone mining waste in river, namely medium-sized gravel which is often called blondos stone, has not been optimally building material. Based on these reasons, it tried use stone porous concrete. Three v...
The work presented includes a review of the state art porous concrete. Its purpose is to evaluate potential use concrete in constructions where level surface runoff justifies it. A literature here has been necessary parameters special consideration have defined dosage permeable mixtures. study definition terms its main components: cement, coarse aggregate, water, additives, and sand, little or ...
