Document Summary

Know different types of concrete (shotcrete, etc. ) A masonry structure formed by combining masonry units with mortar Stone, clay bricks (solid or hollow) and blocks (concrete masonry units) Some countries rely on masonry rather than concrete. Great wall of china, tower of pisa, Needs specialists to do this work - could collapse if not done right - safety hazard. Compressive capacity only - works based on the compr. force between the units. Malta has a ton of sandstone masonry. Placed in molds, vibrated and compacted, and demolded quickly (holds shape) Function: mainly used to build walls (exterior and interior) Load-bearing - structural walls: carry loads from other members. Non-load bearing - walls only carry own weight (i. e. partition wall that doesn"t support floor or roof) Environmental consequences : furnaces used - very industrial process to make bricks. But can bricks be crushed afterwards and reused? (ongoing sustainability question)
