Title: Innovations of James A Ray in Hydraulic Cement Technology
Introduction
James A Ray is an accomplished inventor based in Mantua, OH (US), known for his significant contributions to the field of hydraulic cement technology. With a total of six patents to his name, Ray has developed innovative solutions that enhance the performance and strength of cement mixes.
Latest Patents
Ray's latest patents focus on improving hydraulic cement mixes. One notable invention involves the incorporation of an admixture comprising at least one acetic acid ester of a glycol. This admixture is designed to increase the compressive strength of products made from such mixes. In portland-type cement mixes, these admixtures also serve as set accelerators. In high-alumina cement mixes, they not only enhance strength but also inhibit the spontaneous loss of strength typically associated with high-alumina cements. A preferred admixture identified in his patents is ethylene glycol diacetate, used in amounts of up to about 3.0% by weight based on the weight of the cement.
Another patent details a hydraulic cement mix that includes hydraulic cement, aggregate, and sufficient water for hydraulic setting. This mix also incorporates an additive comprising glycerophosphoric acid or its salts, such as calcium, magnesium, potassium, and sodium glycerophosphate. The additive is present in an amount sufficient to increase the strength of the mix when hardened, generally up to 0.2% by weight, with preferred amounts ranging from 0.005% to 0.2% by weight based on the weight of the cement.
