The empirical method is the most commonly used method of locating control joints and is applicable to most building types. Therefore, it may be prudent to design the lintel to carry the full weight of the wall above it in addition to any superimposed loads. German engineers have been Using the same type of detail as for the unreinforced wall would require the control joint to cross the vertical reinforcement, thereby preventing movement and defeating the purpose of the control joint. If TILT-CRETE application as a cure to the casting slab is delayed for several hours or until the following day, the surface should be moistened with water before application of TILT-CRETE.
