4. Carbon
dioxide
Utilization

5. If cement could be made
without limestone,
theoretically, that could
eliminate many of the
industry’s CO2 emissions.
When that cement is used
to make concrete, the
process will actually
absorb carbon dioxide.

7. Carbonation curing is not only environmentally responsible, but when applied to the concrete block’s
treatment, it can also reduce shrinkage, decrease defects in the finished block units, and reduce
energy required to cure the concrete. The addition of CO2 into concrete production can also result
in higher early strength of the concrete. These higher early-strength gains can allow for producers
to reduce their cement loading, and thus further reduce their CO2 footprint.

11. Concrete that incorporates and reduces carbon dioxide
emissions

14. This curing process takes
24 hours and stores away
three kilograms of CO2
per Cement Masonry
Units by converting them
into a stable mineral,
alongside an additional
kilogram of CO2 that is
pulled from the
surrounding air during
the curing process.
