DEVELOPMENT OF PERVIOUS CONCRETE HAVING STRENGTH ENHANCEMENT ADMIXTURE FOR MANAGING STORMWATER RUNOFF

Effects of Stormwater Runoff from New Development

Most people know that urban runoff is a problem. Few understand just how harmful it can be for rivers and streams. To secure better watershed planning urban runoff control, we must first convince the public and its officials that they are needed. We need to show clearly and convincingly both the nature and the magnitude of the water quality and quantity problems that poorly planned and managed ...

Mix Design Development for Pervious Concrete In Cold Weather Climates

Portland cement pervious concrete (PCPC) is increasingly being used in the United States in sidewalks and parking lots due to its benefits in reducing the amount of runoff water and improving water quality. In the United States, PCPC typically has high porosity and low strength, which has resulted in limited use of pervious concrete in hard wet freeze environments (i.e., the Midwest and Northea...

Investigating the Physical Properties and Runoff Treatment Capability of Pervious Concrete Containing Granular Activated Carbon

Prediction of Pervious Concrete Permeability and Compressive Strength Using Artificial Neural Networks

Pervious concrete is a concrete mixture prepared from cement, aggregates, water, little or no fines, and in some cases 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 analytical prediction modeling o...

Virtual Pervious Concrete: Microstructure, Percolation, and Permeability

As the usage of pervious concrete continues to increase dramatically, a better understanding of the linkages between microstructure, transport properties, and durability will assist suppliers in mixture proportioning and design. This paper presents various virtual pervious concrete microstructural models and compares their percolation characteristics and computed transport properties to those o...
