Across
  1. 1. Type of strength that concrete is primarily designed to resist
  2. 5. High range water reducing admixture,significantly increasing flowability
  3. 8. A horizontal structural element designed to support loads over a span
  4. 9. Very fine byproduct used as a pozzolan to greatly increase concrete strength and reduce permeability
  5. 10. A common supplementary cementitous material(SCM)
  6. 11. General term for reducing the volume of fresh concrete typically by vibration to eliminate air voids
  7. 12. The chemical reaction between cement and water
Down
  1. 2. Separation of concrete components during handling
  2. 3. Ability of concrete to resist weathering and chemical attack
  3. 4. Reaction of CO2 with calcium hydroxide,reducing concrete’s alkalinity
  4. 6. Volume reduction as concrete loses moisture after setting
  5. 7. Measure of how easily liquids can pass through hardened concrete
