Wall Patterns Brick Vectors Photos Files
Grungy red brick blank wall texture. Horizontal wide brickwall background. To construct brick masonry wall we use some bond patterns. Dutch bond is a little bit different. Make usable mortar and state proper proportions of ingredients (lime, sand, etc.). The plumb bob hangs straight down, so the plumb line can be used to make sure that a wall is perfectly vertical and does not lean in any direction.
A perfectly vertical line is said to be plumb. The line stretcher is often set about a sixteenth of an inch away from the wall so that the bricks do not touch it (otherwise they might push the line out).
Distribute loads throughout the structure to achieve maximum strength. This bond is strong and often used for walls which are two-bricks thick. This is often used purely for decorative purposes rather than for load-bearing. Use a hoe to work the water into the cement until it is thoroughly worked in. Do not add more water to the mix than the bag indicates is acceptable. Adding too much water will create a weaker concrete. You must then consolidate the concrete.

To consolidate concrete by spading, insert the spade along the inside surface of the forms, through the layer just placed, and several inches into the layer underneath.
There are many ways to finish concrete surfaces, depending on the effect required. Sometimes you only need to correct surface defects, fill bolt holes, or clean the surface. Begin floating immediately after screeding while the concrete is still plastic and workable. However, too long a delay in troweling results in a surface too hard to finish properly. An unslippery, fine-textured surface can be obtained by troweling lightly over the surface with a circular motion immediately after the first regular troweling. Hairline cracks are usually due to a concentration of water and extremely fine aggregates at the surface. Hydration continues indefinitely at a decreasing rate as long as the mixture contains water and the temperature conditions are favorable. For most structural use, the curing period for cast-in-place concrete is usually 3 days to 2 weeks.
