When preparing brick mortar, it's essential to follow the correct mix ratio to ensure the mortar has the right consistency and strength. The standard blend for brick mortar, which is widely recommended, consists of 6 parts sand, 1 part cement, and 1 part hydrated lime, which is a ratio of 6:1:1.

Here's a simple breakdown:

1. Cement: Acts as the main binding component.
2. Sand: Provides bulk and strength to the mortar.
3. Hydrated Lime: Enhances the workability and durability of the mortar.

By maintaining this 6:1:1 ratio, the mortar achieves an optimal balance of strength and flexibility, which is crucial for the longevity and stability of brickwork. This mix ensures that the mortar has enough binding capacity to hold the bricks together while also allowing for some flexibility, which is important for absorbing any movements or stresses without causing cracks.

Remember, when mixing your mortar, it's important to mix the materials thoroughly to ensure that the cement, sand, and lime are evenly distributed throughout the mixture. Also, the amount of water added should be carefully controlled to achieve a workable consistency that is neither too dry nor too wet, ensuring strong adhesion and ease of use during the brick-laying process.
