Mar Mac is one of the partners Graphene Integrations has worked with. This page introduces the company and points to the graphene products most relevant to its field, infrastructure materials.
About Mar Mac Applied Infrastructure Sciences
According to its website, MarMac Applied Infrastructure Sciences (AIS) is a chemical, engineering and formulations research and development laboratory focused on making infrastructure better. AIS specializes in polymeric coatings, topical treatments and concrete admixtures that extend the serviceable life of the building materials they are applied to, and it is a division of MarMac Manufacturing Company, Inc.

Where this connects to our work
Concrete is a core application for us. Our graphene concrete additive is a liquid concentrate validated at 5% by weight of cement (loading depends on mix design; see TDS). In independent third-party testing in 2023 it gave a 67.7% gain in compressive strength and increased water resistance by 25%. Results depend on the cement, aggregates, water-cement ratio and curing, so we test with each producer in its own mix, and any change to a mix design must be confirmed by the project engineer.
Graphene rebar is a separate effort that is in development. It is not a product yet, and we make no claims about it.

Concrete strength and embodied carbon
Cement is the binder in concrete. Its production releases CO₂ through limestone conversion and energy use, as explained by the IEA. That makes cement quantity an important part of a concrete carbon assessment.
GI’s additive achieved +67.7% compressive strength in third-party testing at the tested 5% supplied-additive dose by cement weight, not 5% pure graphene. This validated strength result supports investigating lower-cement mixes; it does not establish how much cement can be removed. Candidate mixes must meet the same required performance.
Conditional example: if 100 kg of Portland cement is actually avoided at the same required performance, gross avoided cement A1–A3 impact is 100 × 0.919 = 91.9 kg CO₂e. The 100 kg is an example assumption, not a reduction demonstrated by GI. The official US industry-average Portland cement EPD, revised July 2026, Table 4, gives 0.919 kg CO₂e/kg using 2019 production data, covering A1–A3, raw materials through manufacturing—not a current-year plant measurement or whole-life concrete footprint. CO₂e means carbon dioxide equivalent.
This is gross avoided cement-production impact, not measured GI net savings. Net savings require matched-performance mix validation and a consistent lifecycle comparison including additive manufacture, carrier, packaging, transport and all changed mix inputs. Unknown additive impacts are not zero. The strength result does not automatically establish cement reduction, longer service life or carbon capture.
