Can Better Concrete Give Us Better Air?...Yes.

Not many people realize that concrete is the most used man-made product on earth.  Each year, 2.5 billion tons of new cement is produced and used as a key ingredient to make concrete.  However, for every ton of cement produced, there a ton of CO2 is generated! This makes concrete a big contributor to CO2 emissions; more than 5% of the annual total!  More importantly, this creates a big opportunity for CO2 reduction.  By using a concrete with a significantly reduced CO2 footprint, we can all make a bold and measurable step forward in reducing global warming. If that same concrete is more durable and higher performance, then we can reduce the long-term costs of infrastructure.

2X Green provides twice the durability and up to a 70% reduction in CO2 when compared to standard concretes used in drainage and underground infrastructure.  Clearly, the better choice.

Why is Durability in Concrete Important...and Can it Really Be Measured?

Simply speaking, high performance concrete (HPC) is really concrete that is just much more durable.  Durability is important in concrete because the more durable a concrete, the more resistant it is to corrosion, and the more resistant it is to corrosion, the longer it will last.

The US Federal Highway Administration (FHWA) has been a long-time proponent of HPC for (above-ground) bridges and highways because of the increased durability.  In the highly corrosive environments of drainage and underground infrastructure, increased durability ¾ and therefore longer service life ¾ is absolutely critical.

The most common measure of concrete durability is the Rapid Chloride Permeability test (ASTM C-1202).  An alternative measurement method is ACI Life 365.  By any measure, 2X Green is a winner.  More than twice as durable than concretes that are normally specified for drainage and related applications.

CWR Delivers an Integrated Solution, ‘User-Friendly’ and Affordable Alternative

CWR supplies blended cements that are of consistent mix design, testing, certification, quality control and technical support to ensure the concrete solution will meet the asset owner’s most aggressive performance specifications.

This turn-key alternative avoids the unsustainable approach that requires each architect, engineer and asset owner (as well as the local precast and/or ready-mix firm) to become “expert” in SCM’s, sourcing, mix design, and testing.  Rather, it allows these parties to specify durability, service life and other performance characteristics that are relevant to the specific application (e.g., manholes, utility vaults, bridges, etc.) and do so with the confidence that they can receive the most durable, green infrastructure from local sources.

CWR delivers results to architects, engineers, asset owners, governments, precast/ready-mix companies, taxpayers and the environment.

CWR Delivers the Leading HPC Technical Team (click here for selected team bios)

CWR has assembled an unparalleled team of industry experts and engineers led by John Bickley, Denis Mitchell and Sid Mindess.  This team delivers decades of expertise in cement, concrete, HPC, SCM procurement and blending of specialty cements; HPC mix design for optimal durability; and HPC mix design for optimal GHG reduction and HPC Performance Specifications.
