Properties of porous concrete from waste crushed concrete
Tests carried out on porous concrete were: void ratio, coefficient of permeability, compressive and flexural strengths. The effect of recycled aggregate on total void ratio, strength and permeability was examined. Styrene butadiene rubber-based redispersible polymer powder and latex were introduced to mixtures to improve strength properties.

Void ratio Geotechdatafo
Void ratio is usually used in parallel with soil porosity (n), which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: e = n /(1-n) and n = e / (1+e) The value of void ratio depends on the consistence and packing of the soil.

Relationship of void ration to rock size/shap Soil
Jan 05, 2009· When they are nested as close together as possible, the void ratio is 0.35. So you can see you need a rock material that is single sized, not necessarily spheres, that when in its tightest position, results in a void ratio of about 0.4. The diameters don't matter for this as long as they all are the same.

Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).. There are many ways to test porosity in a
