INTERIM TRANSITION: Are there any questions about the demonstration? If not, let’s move on. (On SLIDE #27) e. Vertical reinforcement bars are placed in the cores, and filled with concrete or mortar. When block walls will be supporting heavy structural loads, cores will be filled with a 1:2:4 concrete mix ratio at places where girders will rest. The cores must be filled from the footing to the bearing surface of the wall. f. Horizontal truss type reinforcement is placed every second course (16 inches) vertically up the wall to reduce shrinkage and settlement cracks. g. In walls 20 feet and longer, 8" x 16" vertical pilasters are placed every 10' and filled with concrete to make the walls more rigid. (On SLIDE #28) TRANSITION: We have just covered the fundamental characteristics of masonry building materials. Are there any questions? OPPORTUNITY FOR QUESTIONS: 1. QUESTIONS FROM THE CLASS: Do you have any questions concerning the characteristics of masonry building materials? (Answer student’s questions.) 2. QUESTIONS TO THE CLASS: a. What are the two types of concrete block? ANSWER: Heavyweight, and Lightweight. b. What size are CMU’s manufactured? ANSWER: Full and Half block sizes. (BREAK 10 Min) TRANSITION: Before the trial we covered the fundamental characteristics of masonry building materials. Do you have any questions? If not, let’s discuss the fundamental characteristics of wooden building materials. (On #29)
