What is the mortar mix ratio cement to sand?

• A. 1:3
• B. 1:2
• C. 3:1
• D. 2:1

Answer: (A)

One part cement to three parts sand provides a working, durable mortar that bonds masonry well without being too stiff. The cement acts as the binder that holds bricks or blocks together, while the sand supplies bulk, reduces shrinkage, and makes the mix workable for filling joints. If you add more cement, the mortar becomes stiffer and harder to lay, increasing the risk of cracking as it dries and making it difficult to trowel and finish neatly. If you use less cement, the mortar loses strength and bonding capability, which can lead to weaker joints. For general-purpose masonry, the one-to-three ratio strikes a practical balance between strength and workability.
