Suitably replace Type N or O mortars by accepting the limitation that Natural Hydraulic Lime mortars set slower. Standard Type N and O mortars meet their criteria at various intervals such as 28 day strength. Brick and stone walls built with Natural Hydraulic Lime mortars can continue to be built upon with no delay in continuing the work on each successive day for standard walls up to 12" thick. The final strengths of NHL mortars will be realised over time and the mortar will adequately provide weight distribution for the veneers until final strengths are achieved.

Check with us regarding your application. We can create similar Type S and Type M mortars for below grade building and where increased strength is needed with the addition of special non-Portland cement Pozzolans so that Green Technology is adhered to throughout the entire selection of mortars for building Sustainable Buildings.

The Relationship between the Elasticity Moduli and Flexural Strength noted above is very important. The higher the number reaches for the Elasticity Moduli translates to how much more brittle the mortar is. The importance of higher elasticity in mortar is the mortar's ability to deflect and recover with expansion and contraction. Ordinary Portland Cement has the same expansion and contraction coefficient as that of steel.

The relationship between the number for measuring final Flexural strength of mortar and that number measuring the final Compressive strength of mortar is also very important. NHL mortars have a smaller gap between the final performance numbers for Flexural strength and Compressive strengths in comparison to Ordinary Portland cement mixes. This is beneficial to creating durable mortar.
