PLAN replaces 50% of Portland cement with latest cement

Executive Summary

• Progressive Planet announced the development of a proprietary Limestone Calcined Diatomite (LCD) cement that can replace up to 50 % of Portland cement while meeting ASTM C618 compressive‑strength requirements.
• The company filed a U.S. provisional patent application for the LCD composition and a trademark application for “Planet LCD Cement.”
• A grand opening of the Calgary‑based C‑Quester™ Centre of Sustainable Solutions is scheduled for March 26, 2026, with plans to produce LCD cement, develop a dedicated plasticizer, offer contract testing services, and advance other supplementary cementing materials (SCM).

Key Details

• LCD Cement Innovation – Named “Planet LCD Cement,” it uses diatomaceous earth, limestone, and gypsum; tests show successful 20 %, 35 % and 50 % weight‑for‑weight Portland replacement with compressive strengths meeting ASTM C618.
• Intellectual Property – Canadian trademark filed; U.S. provisional patent application submitted for the LCD composition, with intent to file internationally within one year.
• Calgary Lab Grand Opening – Set for Thursday, March 26, 2026; will focus on:
• Scaling LCD cement production using waste diatomaceous earth.
• Developing a proprietary plasticizer tailored for LCD cement.
• Creating variants of “Gladiator” SCM.
• Providing contractual testing services as a future profit centre.
• Kamloops Lab Activities – Continuing quality‑control testing of PozGlass SCM; developing specialty glass‑nanoparticle additives; invested in particle‑size analyzer capable of detecting particles down to 10 nm.
• PozGlass SCM Pilot Plant Update – Phase 1 major components installed; roof, siding, and equipment energization underway. Targeted start of dry glass powder production by end of Q4 2026 (April 30, 2026), pending electrical service connection.
• Management Comments – CEO Steve Harpur highlighted cost advantages of waste diatomaceous earth versus metakaolin; CTO Dr. Doug Brown emphasized the reactivity of silica in natural pozzolans; Process Engineer Sam MacDonald noted timeline for pilot plant commissioning.
