With an ever-changing landscape to the availability of pozzolans for the industries that we serve, CR Minerals has patented several of our products for use in the concrete industry as well as the oil and gas sector. These patents offer product protection for our customers and ensures that the performance they receive is the same high-end design that was developed through years of product development.
Our patents fall into two broad categories. The first category surrounds remediating fly ash to produce a material (Tephra® RFA) that can meet a Class F or Class C ASTM C618 product specification. The materials used to produce these Tephra® RFAs includes waste fly ash, Class C fly ash, natural pozzolans including metakaolin, slag and other materials. Our patents in this space include USPTO numbers 9561983, 9611174, 10017418, 10689292, 10370295, and 10377667.
The second category of patents encompasses using our technology and applying it to oil and gas applications. Materials used to make these Tephra® OG products are similar to those used to make our Tephra® RFAs and result in cementitious products that have enhanced downhole performance. Our patents for these applications include 104576001 and 10829414.
