Holcim’s masonry products offer quality, flexibility, and selection. Ranging from basic ASTM C91 Types M, S and N to a spectrum of pigmented masonry available in 70 standard colors and endless customized options, our masonry cement products to can meet any design need while helping to reduce the carbon footprint of the construction industry.

In independent testing, our Mortar Cement products exceeded the flexural bond strengths required in:

  • ASTM C 1329 Standard Specification for Mortar Cement
  • International Building Code Standard 2103.7 Mortar
  • CSA-A3002 Masonry and Mortar Cement

They also achieved flexural bond and compressive strengths that meet all seismic zone requirements, enhancing structural stability and maintaining the margin of safety.

Masonry Cement is specially-formulated to ensure a uniform texture and color at a quality level that can be used for almost any brick, block and stone masonry construction. Moreover, the lower global warming potential (GWP) of Masonry Cement and Mortar Cement supports Holcim in leading the industry in the reduction of carbon emissions and the shift toward low-carbon construction.

  • Masonry Cements are composed of Portland cement, plasticizers and air entraining additives. We proportion our masonry segments at the plant under controlled conditions in a single blending operation which provides a more uniform mortar and eliminates the need to batch cement and mortars in the field. In addition, their properties support industry and global sustainability initiatives:
    • GWP, Masonry Type S1 —661 (AR5)
    • GWP, Masonry Type N1 —566 (AR5)
    • Ozone depletion potential (ODP), Masonry Type S2 —1.5E-05
    • Ozone depletion potential (ODP), Masonry Type N2 —1.4E-05
    • Consumption of freshwater, Masonry Type S and N3 —0.0
  • Mortar Cement offers superior performance: durability, weather resistance and aesthetics. It is suitable for all masonry construction, especially projects that require higher flexural bond and compressive strengths.
