Common types of mortar on the market

Mortar comes in various types, each formulated to suit specific construction needs. Here are a few common types of mortar on the market:
Type M Mortar: Type M mortar is the most robust, ideal for load-bearing structures and areas subject to high compressive forces. It is commonly used in foundations, retaining walls, and heavy masonry constructions.
Type S Mortar: Type S mortar offers a balanced mix of strength and durability, making it suitable for various applications. It is commonly used in masonry work that requires moderate to high power, such as walls and outdoor structures.
Type N Mortar: Type N mortar is versatile with medium compressive strength. It is commonly used in non-load-bearing walls, indoor projects, and exterior veneers.
Type O Mortar: Type O mortar is a low-strength mortar suitable for applications such as repositioning old structures and historic restoration projects.
Type K Mortar: Type K mortar is the weakest among the mortar types and is rarely used in modern construction.

What is the Most Common Mortar?

Of the different types of mortar, Type N is the most commonly used for general masonry applications. Its workability makes it suitable for a variety of projects, including interior and exterior masonry walls, chimneys and other non-load-bearing structures. Type N mortar offers a good compromise between cost-effectiveness and performance and is preferred by many developers.

What are the Components of Mortar?

Mortar is composed of several essential components, each contributing to its properties and performance:
Portland Cement: Portland cement is the primary binder in mortar, providing the adhesive properties that bond masonry units together.
Sand: Sand is the primary aggregate in mortar, responsible for the bulk and workability of the mixture. The choice of sand type and gradation affects the strength and texture of the mortar.
Water: Water is added to the dry mix to facilitate cement hydration, enabling it to bind the sand particles together.
Lime (Optional): In some mortar formulations, lime is added to enhance workability, plasticity, and water retention. It also improves the mortar’s resistance to freeze-thaw cycles.
Additives (Optional): Various additives, such as HPMC, can be incorporated into the mortar to enhance specific properties.

What is the Role of HPMC in Mortar?

In short, mortar, a vital construction component, is crucial in holding masonry units together and creating robust structures. The different types of mortar cater to various construction needs, striking a balance between strength and workability. HPMC is a valuable additive to make mortar more reliable and durable.
