  • Method of forming a self-consolidating concrete construction with self-roughening properties
    Patent number: 10941075
    Abstract: Adding a small amount of lightweight course aggregate to a normal weight concrete mix to produce a clean, rough top surface so that manual or mechanical roughing of the top surface is not necessary. The lightweight course aggregate will float to the surface, and make a rough surface so that the bond and shear resistance of the interface (cold joint) between previously placed and newly placed concrete will be as strong as a manually roughened joint.
    Type: Grant
    Filed: May 19, 2016
    Date of Patent: March 9, 2021
    Assignee: Georgia Tech Research Corporation
