Title: Innovations by Michael R. Kelley in Lightweight Concrete Technology
Introduction
Michael R. Kelley is an accomplished inventor based in Butler, PA (US), known for his significant contributions to the field of concrete technology. With a total of five patents to his name, Kelley has focused on developing innovative lightweight concrete compositions and methods for placing concrete.
Latest Patents
One of Kelley's latest patents is for a lightweight ready-mix concrete composition. This composition includes 8-20 volume percent cement, 11-50 volume percent sand, 10-31 volume percent prepuff particles, 9-40 volume percent coarse aggregate, and 10-22 volume percent water, ensuring that the total does not exceed 100 volume percent. The prepuff particles used in this composition have an average particle diameter ranging from 0.2 mm to 8 mm, a bulk density between 0.02 g/cc and 0.64 g/cc, and an aspect ratio of 1 to 3. The slump value of this composition, measured according to ASTM C 143, ranges from 2 to 8 inches. After setting for 28 days, the concrete achieves a compressive strength of at least 1400 psi, as tested according to ASTM C39.
Another notable patent involves a method of placing concrete compositions. This method includes combining 3-40 volume percent cement, 5-50 volume percent fine aggregate, 5-50 volume percent coarse aggregate, and 10-22 volume percent water. Additionally, 1.5-40 volume percent of prepuff particles is added to form the concrete composition. The concrete is then pumped to a higher elevation than the delivery point for placement. This composition contains less than 30 volume percent of other lightweight aggregates, and the slump value of the placed concrete is greater than 1 inch, with a density ranging from about 40 to about 135 lb./ft.
