Latest Patents
Crocker’s latest innovations include two notable patents focused on lightweight cementitious compositions. The first patent describes a lightweight cementitious composition that involves a dry mixture containing a hydraulic cement component and a lightweight aggregate component, which is designed to yield a workable slurry upon the addition of water. This slurry, containing at least 4 volume percent entrained air, sets into a concrete mass characterized by a strength of 2500 psi and a density of 115 ppcf or less. The hydraulic cement component is versatile, including Type S, Type M, or Type N masonry cements, alongside pozzolanic or expansive cements, and potentially a Type I, Type II, or Type III portland cement.
The second patent outlines a similar lightweight cementitious composition. It emphasizes producing a workable paste upon mixing with water, which again incorporates at least two to three types of cement constituents. Key characteristics of these formulations include a bulk density of around 85 pounds per cubic foot and a manageable slump loss of no more than 2 inches within half an hour after mixing. This innovative product is designed for convenient packaging, weighing no more than 50 pounds per container.
