Can you use portland cement for mortar?
You can make mortar with just Portland cement, sand and water. The mortar that I used to permanently attach my brick and stone to my patios did not contain any hydrated lime.

What is the most important thing to consider when building a masonry wall?
One of the most important items when constructing a masonry wall is to insure its ability to keep the water out, often referred to as water permeance. Both masonry cement mortars and P/L blend mortars have the capability of providing for water permeance, given they are used effectively by the mason.
What is the ASTM C91 for cement?
Masonry cements in Types N, S, and M are covered by ASTM C91, Standard Specification for Masonry Cements.
What is Portland lime?
Portland/lime blends are manufactured in a blending facility using portland cement and hydrated Type S lime. The lime provides for workability, much the same as plasticizers do for masonry cements. Lime is made up of hexagonal shaped hydroxide crystals. These crystals are thin, flat particles which slip and slide over one another, but never separate completely, acting as a lubricant. The particles of lime in a portland/lime blend are very fine, helping to increase its ability to retain water effectively, again to help with workability.
Why does masonry stain?
However, this “stain” occurs when water dissolves the soluble salts contained in all masonry materials, the water then evaporates, and the salts are left behind. This occurrence is common on newly constructed masonry structures, due to the inherent moisture trapped within the structure itself.
Why do cement based products need water?
This is due to the fact that all cement based products need water to hydrate all of the cement particles. When a specimen is stored in a laboratory without atmospheric moisture, the cement particles are not allowed to hydrate completely, decreasing bond and water permeance capabilities.
Why does my wall not have water permeation?
The most common reason for a wall to lack water permeance is the mason was not familiar with the product being used and thus was unable to get full, complete head and bed joints.

How did Portland cement get its name?
It got its name because it had a similar color to a widely used stone in the Isle of Portland off the coast of England. Portland cement was able to attain very quick setting times compared to lime, but its strengths were fairly limited compared to natural cements and it didn’t catch on for about 50 years.

Why is it important to select the right mortar for restoring a building?
For those restoring a historic building built before 1930 it’s important to select the right mortar to avoid spalling bricks. When the selected mortar is harder than the brick it surrounds then the brick will become sacrificial and worn away rather than the mortar. A sign of impending disaster.
Is Portland cement a mortar?
The more portland cement is added to any mortar the harder it gets, and the harder it gets the greater potential you have to damage brick. In today’s home stores lime is largely missing from all mortars. The variety of strengths available today is mostly accomplished by other additives and air-entrenching in the mortar.
