The purpose of this study was to develop porous concrete with acceptable permeability and strength using recycled aggregate from waste crushed concrete. The optimum
01.10.2013· Most economical means to utilize recycled aggregate could be porous concrete which uses more than 80% aggregates. Porous concrete contains little or no fine aggregate, using an adequate amount of cement paste to coat and bind the aggregate particles to create a system of high porosity and interconnected voids to quickly drain off water, its poresity depends upon application and size of
Pattison produces POROUS FILL products in our state-of-the-art, jaw/cone crushing plant. Our crushing plant is built around a sophisticated compression crushing technology that reduces fines generation and increase fractured faces. Where is Porous Fill Used. Pattison POROUS
01.01.2019· The crushing mechanism interferes directly with recycled aggregate properties at different levels: particle size distribution, aggregate shape, generation of micro-fractures, as well as regarding the detachment of porous hardened cement paste from particle surface in order to recover pure, non-porous natural aggregates. However, crusher selection in the recycling industry is mostly carried out
30.06.2011· CCA is more porous than virgin aggregate. Mark Wachal, senior project manager of Recycled Materials Co., Arvada, Colo., says CCA is about 10% lighter than virgin aggregate, due to its porosity and the presence of paste with lower density than traditional mineral aggregate. Thus, CCA—combined with the fine aggregate or “dust” from the crushing
12.09.2014· A “good” porous aggregate (Image 2) should be poorly-graded from 3/8” to ¾” diameter; with 25 to 40% porosity. It should pass the heaviest of rainfall, is easily rutted/shoved and nearly impossible to suitably compact. Such good porous aggregate

The purpose of this study was to develop porous concrete with acceptable permeability and strength using recycled aggregate from waste crushed concrete. The optimum mix proportions were employed to prepare porous concretes using normal and recycled aggregates. Tests carried out on porous concrete were: void ratio, coefficient of permeability, compressive and flexural strengths. The effect of recycled
The hammer head of the hammer crusher has a shearing effect. The materials crushed by the hammer crusher will form internal cracks, which can promote some materials to be squeezed and ground at the bottom of the hammer crusher, so cement plants like to use it. The hammer crusher crushes materials, which is convenient for the ball mill in the subsequent process to grind materials. However, in the aggregate industry, this kind of crack will cause the aggregate
12.09.2014· A “good” porous aggregate (Image 2) should be poorly-graded from 3/8” to ¾” diameter; with 25 to 40% porosity. It should pass the heaviest of rainfall, is easily rutted/shoved and nearly impossible to suitably compact. Such good porous aggregate is often called open-graded base course (OBGC) when used under pavements.

Porous concrete or asphalt surfaces are made up of a coarse aggregate that is coated in mortar or cement paste. This creates a structure in which there are countless pathways for water to trickle through the surface and down into a collection area or directly into the soil. In theory, this is a great idea. But, there are a variety of ways in which this system can fail you.
