The Composition of Contemporary Mortar

What are the cementitious materials commonly found in contemporary mortar?

a. portland cement
b. lime
c. portland cement and sand
d. portland cement and lime
e. portland cement, lime, and sand

Answer:

The cementitious materials in contemporary mortar commonly include portland cement, lime, and sand.

The cementitious materials in contemporary mortar consist of a combination of binders and aggregates to provide a balance of strength, workability, and adhesion for building and construction work.

Portland cement is a primary binder used in construction that sets, hardens, and adheres to other materials. Lime (calcium oxide) is often used alongside Portland cement to improve workability and water retention. Sand acts as a fine aggregate, providing bulk and strength to the mortar.

The combination of portland cement, lime, and sand is the most commonly used in contemporary mortar mixtures, especially for masonry work. This blend offers a good balance between strength and workability, ensuring suitable setting time, structural strength, plasticity, and adherence for construction purposes.
