What is the ideal mixing ratio for mortar?

• A. One part cement to three parts sand
• B. One part cement to two parts sand
• C. Two parts cement to one part sand
• D. One part cement to four parts sand

Answer: (B)

The ideal mixing ratio for mortar is one part cement to two parts sand because this combination offers a good balance of workability and strength. This ratio allows for sufficient binding capacity while maintaining a workable consistency that can be easily applied and shaped. The one-to-two ratio ensures that the mortar has enough cement to achieve strength without becoming too rigid or difficult to work with. Using this ratio also helps in achieving proper adhesion when using mortar for laying bricks or blocks, as it provides enough paste to fill the voids between the materials, creating a strong bond. Additionally, this mix supports flexibility and resistance to cracking, which is essential for durable masonry work. Other mixing ratios, such as one part cement to three parts sand, may create mortar that is too weak and could compromise the structural integrity of the work. On the other hand, a mix like two parts cement to one part sand could lead to a very rigid, less workable mixture that may not adhere properly. The one part cement to four parts sand would produce a mixture that is too sandy, resulting in poor bonding and inadequate structural support.
