Sunrise Resources plc advised that it has applied to the California Department of Transport for conditional approval of CS natural pozzolan for use in California State infrastructure projects. Caltrans is the Government body responsible for the award of State funded infrastructure construction projects in California. Caltrans Standard Specifications for concrete mandate the use of supplementary cementitious materials such as natural pozzolan in order to improve the durability and sustainability of its concrete structures.
In order for a construction material to be used in a Caltrans project it must be officially approved and listed on Caltrans's Authorized Materials List. In order to be listed, a material must be commercially available with 6 months test data from production. However, it has recently become possible for new sources of construction materials to be approved on a conditional basis and, in the case of natural pozzolan, it must meet the specifications for 1AASHTO M295 and 2ASTM C1567.
Caltrans will test the CS natural pozzolan against these specifications. The Company is confident that its CS natural pozzolan meets these specifications based on its own independent testing under these standards.
