Progressive Planet achieves technical milestone on fly ash alternative
Progressive Planet Solutions Inc., a developer of natural pozzolan properties in BC, Canada, is pleased to announce that its project to modify the rheology of zeolite from the Z-1 Zeolite Quarry has been successful.
On December 9, 2019, Progressive Planet announced that it had signed an agreement with the University of Alberta to develop an alternative to fly ash for use in the cement industry. The project was to end on April 30, 2020. The goal of the project was to modify the rheology of its zeolite so that it possessed similar rheology to commercially available fly ash.
On March 10, 2020, the company released a shareholder update which disclosed that the rheology (slump) had been improved with a combination of various inputs which will remain proprietary; however, one input in the blend which was disclosed was pulverized, recycled glass.
Progressive Planet is pleased to announce that it has received an additional update from the University of Alberta which revealed that the revised proprietary mix design achieved a slump that has exceeded the target slump of the fly ash based mix design.
The CSA tests which need be completed include Compressive Strength, Alkali-silica Reaction, Sulphate Resistance, and Freeze-thaw Resistance. In addition, one ASTM test will be completed to analyze air voids.
The longest test is the Sulphate Resistance and this test has a duration of eight months. As a result, the company will be targeting the 2021 construction season to have a commercial product that it can offer as a competitive alternative to fly ash to the ready mix and pre-cast concrete industries in BC and Alberta.
