PROMASONRY Mortar Sand meets or exceeds ASTM C-144 specification for masonry mortar aggregate.
Can be mixed with Portland cement to achieve a high performance mortar, paver base, paver joints, general landscaping, traction in snow and icy conditions.
PROMASONRY Mortar Sand can be mixed with Portland cement to achieve a high performance mortar. Below are two charts for proportioning mixes according to ASTM C-270 standards.
- The first chart specifies a Portland cement and hydrated lime based mix.
- The second chart specifies a Portland cement or masonry cement based mix.
- The left panel lists each mortar type and defines how they are most commonly used.
Mortar Types and Strengths:
Type M – Very high strength mortar (2500+ psi or 17.2+ MPa) commonly used in exterior applications at or below grade.
Type S – High strength mortar (1800+ psi or 12.4+ MPa) commonly used in exterior load bearing applications above or below grade
Type N – Moderate strength mortar (750+ psi or 5.2+ MPa) commonly used in interior or exterior non load bearing applications at or above grade
Type O – Low Strength mortar (350+ psi or 2.4+ MPa) commonly used in tuck pointing and interior non-load bearing applications
Type K – Very low Strength mortar typically used when tuck pointing historic structures
