How to Choose the Right Mortar Mix Type: N, O, S, or M

Oct 26, 2020 · Type N mortar mix has a medium compressive strength and it is composed of 1 part Portland cement, 1 part lime, and 6 parts sand. It is considered to be a general-purpose mix, useful for above grade, exterior, and interior load-bearing installations. It is also the preferred mortar mix for soft stone masonry.

Portland Cement Type I, II, III: Which to use in a ...

Type II is a moderate sulfate resistant cement, important when concrete is cast against soil that has moderate sulfate levels, but irrelevant to concrete countertops. Type III is a high early strength cement. It is ground finer and reacts faster than Type I, so the early compressive strength gains are greater.

How do I obtain high early strength concrete?

High early strength concrete (2500-3500 psi compressive in 24 hours) is usually accomplished using Type III high-early strength cement (see Table 1), high cement content (600-1000 lb/cu yd), and lower water-cement ratios (0.3 to 0.45 by weight). Super-plasticizers are also used to make the concrete mixture more workable during placement.

Strength of Concrete vs Grades of Cement

The strength of these cements further increases with time and at 90 days a good number of cements have C/S beyond 500 kg/sq. cm. Since the cements have good strength, these can be used for pavement quality concrete. Portland Pozzolana cements as per IS: 1489 (part – I) were produced for durability of structure rather than for higher strength.
