EPD Verified Certificate

Surface Tech announced today that it has completed the verification process to achieve an Environmental Product Declaration for JUNO C33 its advanced alternative supplementary cementitious/fine aggregate material (SCM).

An Environmental Product Declaration (EPD) is a transparent, objective report that details what a product is made of and how it impacts the environment across its entire life cycle. The EPD is an independently verified and registered document that can help construction projects earn credits for LEED v4 and other green building rating systems. EPDs satisfy the requirements of Product Category Rules (PCR) and follow international standards, including ISO 14044, ISO 14025, and ISO 21930.

SCM products are gaining in importance as producers seek new ways to decrease the amount of cement used in concrete mixes. Cement production is recognized as one of the largest contributors to global greenhouse CO2 gas emissions. Using less cement helps decrease CO2 build-up in the atmosphere and helps the environment.

JUNO C33 can be used to partially substitute traditional cement binders and/or fine aggregates in standard concretes. 

In addition to offsetting the use of traditional cement, the science behind JUNO C33 focuses its mineral material composition to increase the strength-bearing microstructure of concrete, making it stronger and last longer.

JUNO C33 also has a positive impact on fresh concrete by maintaining the creaminess needed to allow grey concrete to go down the chute into the framework.

JUNO C33 is easily integrated into existing plant operations, including silo, hopper, supersacks, bags, and dissolvable bags. Using JUNO C33 as an SCM can also result in cost savings, depending on the mix design.
