Prediction of Pervious Concrete Permeability and Compressive [PDF]

, 2020
: admixtures. The hydrological property of pervious concrete is the primary reason for its reappearance in construction. Much research has been conducted on plain concrete, but little attention has been paid to porous concrete, particularly to the ...

Research on the strength prediction for pervious concrete based on design porosity and water-to-cement ratio

Reviews on Advanced Materials Science
The strength prediction of pervious concrete is hard to implement for the mix design due to the porous structure. This work studied the influence of the water-to-cement ratio on the fluidity, viscosity, and mechanical properties of cement paste.

Pervious concrete: a state-of-the-art review

Journal of Materials and Engineering Structures, 2020
Pervious concrete is a special type of concrete, achieved by either minimizing or excluding the sand from the normal concrete mix. In recent years, the practice of pervious concrete as a pavement material in small volume roads and parking lots has added ...

Innovative high-strength, high-permeability concrete for large-scale applications in permeable subgrade of highway tunnel

Case Studies in Construction Materials
The durability of concrete roads in mountainous regions may be reduced due to underground water infiltration and surface water erosion within highway tunnels. A promising solution is the use of pervious concrete as a drainage subgrade layer to drain away
