What is a key factor to consider when laying bricks for structural integrity?

When laying bricks, moisture content is a critical factor to consider for ensuring structural integrity. The moisture in the bricks and the mortar affects the curing process and the overall strength of the masonry. If the moisture content is too high or too low, it can compromise the bond between the bricks and the mortar, leading to issues such as cracking, poor adhesion, and a weakened structure over time. Proper moisture levels allow the mortar to hydrate effectively, facilitating a strong bond that supports the structural load and withstands environmental pressures. Keeping moisture levels balanced helps achieve the desired durability and longevity of the wall or structure being built.

While weather conditions can certainly impact the drying process and working conditions, they do not directly affect the bond strength as moisture content does. Color variation and brick size, while relevant to aesthetic and fit considerations, do not play a direct role in the structural integrity of the masonry.
