CS PROJECT UPDATE - CALTRANS APPROVAL TO AUTHORIZED LIST
Further to its announcement of 11 May 2022, Sunrise Resources plc is pleased to advise that, its CS Natural Pozzolan has now been conditionally approved by the California Department of Transport ("Caltrans") for use in California State infrastructure projects, having successfully passed Caltrans's own independent compliance testing.
CS Natural Pozzolan is now listed on the Caltrans List of Approved Materials for Cementitious Materials for use in Concrete1.
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 ("SCMs") such as natural pozzolan in order to improve the durability and sustainability of its concrete structures. Further information on the role of natural pozzolan in sustainable development can be found in the Company's news release of 9 May 2022.
It has only recently become possible for new sources of construction materials to be approved on a conditional basis. Approval is conditional until six monthly test results from production runs have been submitted by the Company showing compliance with specifications. In the case of natural pozzolan, it must meet the specifications for AASHTO M2952 and ASTM C15673,. In order to give its conditional approval, Caltrans has successfully tested samples of CS Natural Pozzolan for compliance.
Commenting today, Executive Chairman Patrick Cheetham said: "I am delighted that Caltrans has conditionally approved the CS Natural Pozzolan. This is good news for the CS Project. Whilst we were confident that the CS Natural Pozzolan would pass Caltrans's testing procedures, this is an important step forward as many concrete specifiers look to this list as an independent endorsement when specifying for a wider range of non-Caltrans projects."
