A Brighter Future For California With PLC

Dec 7

Imagine if the iconic Bixby Creek Bridge on California’s coast saved 10% of its CO2 emissions, or 174 metric tons,* when built in 1932. Now imagine if every project in California since then did the same.

Be a catalyst for this change for future generations by making a simple change.

Shaping California’s Future with PLC

PLC is the acronym for Portland Limestone Cement, a proven substitution for traditional Portland cement. PLC is an embodied carbon game-changer with equal performance and up to 10% fewer CO2 emissions.

Every Step Matters

The global urgency for action to protect the climate is more evident than ever. Taking steps today to reduce carbon impacts sets a positive course for the future. These objectives have inspired bold commitments from Architecture 2030 and SE 2050. The State of California goals are for a 40% reduction in CO2 by 2030 and net-zero emissions by 2045. Specifying PLC is a key step in meeting these goals. Taking action, the California cement industry has developed an ambitious Carbon Neutrality plan for CO2 emissions reduction. View this transformational plan on the CNCA website at cncement.org.

Direct Replacement for Portland Cement

PLC is simple to produce, a direct replacement cement using existing materials at current production plants. This cement formulation is proven with decades of performance around the globe.

Technical Data and Specifications

Typical concrete specifications utilize ASTM C150 Portland Cement. To achieve carbon emission reductions, it is important to add ASTM C595, Type IL, Blended Hydraulic Cement to the specification. Since both C150 and C595 cements provide essentially the same performance levels, the specification may be limited to C595 cement to ensure carbon emission reductions. Additional specification and performance information is available in the CNCA Specification/Technical Sheet.

Measuring Impact of CO2 Savings

Measurement of impacts is vital. CNCA can help you calculate your CO2 reduction through PLC on projects. Architects and engineers can use this information to envision the wider-scale effects. Benefits are magnified when a firm applies these metrics throughout an entire portfolio of projects.
