Locks can be obtained with a latch bolt so that the door can be kept in a closed position without using the key. Locks in doors are usually fixed at a height of 1050mm. Some examples of common locks and latches used in farm buildings are illustrated in Figure 3.39.
Since concrete cannot shrink around a corner, stress will cause the concrete to crack from the point of that corner. Plastic shrinkage cracks are typically very narrow in width and barely visible. While nearly invisible, it is important to remember that plastic shrinkage cracks don't just exist on the surface, they extend throughout the entire thickness of the slab.
