VANCOUVER, BC, June 23, 2021 /CNW/ - Progressive Planet
Solutions Inc. (TSXV: PLAN) ("PLAN" or the "Company"), is pleased
to announce the positive accelerated-cure Resistance to Chloride
Ion Penetration (RCP) test results for its PozGlass™ SCM product.
The Company is focused on delivering economic and eco-friendly
solutions for the cement and concrete industry.
Based on the better-than-expected accelerated-cure RCP test
results, management believes the market potential for the
proprietary formulation and process in the blending of natural
pozzolans and recovered post-consumer glass could be larger than
originally expected.
Measuring RCP is essential because permeability is a factor in
the long-term durability of concrete. Lower permeability results in
longer lasting concrete because the metal rebar in the concrete is
better protected from outside chemical attack. This is especially
important in coastal saltwater environments, where the bulk of the
world's concrete is produced, and applications where de-icing salts
are used.
The 28-day accelerated-cure RCP testing was led by Dr.
Michael Thomas from C&CS
Atlantic. Dr. Thomas is a Professor in the Department of Civil
Engineering at the University of New
Brunswick (UNB), a registered Professional Engineer in the
province of New Brunswick and has
been working in the field of cement and concrete research since
1983.
Dr. Thomas's main research interests include concrete durability
and the use of industrial by-products such as pozzolans and slag.
He has authored more than 200 technical papers and reports
including the book "Supplementary Cementing Materials in
Concrete".
"The 28-day accelerated-cure test results give an indication of
the result expected at 91 days with standard curing. As such, the
value of 1035 Coulombs at 28 days for the concrete mix with 25%
PozGlass SCM indicates excellent performance that should
comfortably meet the requirements for a C-1 exposure (1500 Coulombs
at 91 days) and possibly C-XL exposure (1000 Coulombs at 91 days),"
stated Dr. Thomas. "I am confident that the C-XL requirement would
be met easily at a slightly higher replacement (such as 30%
PozGlass SCM)."
"The highest durability performance expectations in CSA A23.1
(latest version) are for C-XL concrete, which is structurally
reinforced concrete exposed to chlorides or other severe
environments with or without freezing and thawing conditions.
PozGlass SCM shows the potential to be used for the most demanding
C-XL applications and, therefore, greatly reduces the risks for
concrete producer's everyday applications as well," says
Ian Grant, who spent 5 years as a
senior executive in the cement and concrete industry prior to
becoming PLAN's VP of Business Development.
The full 91-day RCP test results will be available from Dr.
Thomas by end of July 2021. In
addition, the 6-month sulphate resistance test results will be
completed in early October 2021.
The Company has also received 56-day compressive strength
results from Dr. Thomas with strengths performing as expected.
PozGlass SCM has climbed to 56.3 MPa at 56 days, while the Portland
Cement control was at 59.1 MPa.
"With 25% replacement I would expect the strength to be lower at
early age but to see more strength gain with age to the extent that
strength parity is eventually reached and the pozzolan mix being
superior thereafter. The precise timing of this depends mainly on
the properties of the pozzolan and temperature," says Dr. Thomas.
"Achieving near strength parity at 56 days is quite typical of many
pozzolans."
PLAN is using the information gathered in this phase of testing
to facilitate early discussions with concrete producers as the
company moves towards full-scale commercialization of PozGlass SCM
in Western Canada and the Pacific
Northwest.
"Our intent with PozGlass SCM is to radically reduce the carbon
footprint of cement. When concrete lasts longer, less Portland
Cement is produced. Longer lasting concrete is a key to reducing
CO2 emissions and part of our goal of building a better, cleaner
world," stated Steve Harpur,
CEO.
ABOUT PROGRESSIVE PLANET
Progressive Planet is an emerging leader in supplying solutions
for a livable planet by developing low carbon, pozzolan-based,
cementing products which replace equivalent amounts of Portland
Cement and fly ash in concrete. The production of Portland Cement
is the second largest global generator of CO2 emissions.
Progressive Planet operates its flagship Z1 Natural Pozzolan
Quarry in Cache Creek, British
Columbia and is earning a 100% interest in the Z2 Natural
Pozzolan Property near Falkland,
BC and earning a 100% interest in the Heffley Creek Metals
and Natural Pozzolan Property. All three properties are within a
one-hour drive of Kamloops, BC, an
industrial hub with rail access to Canadian and US markets.
