MATERIALS CE 200 SEMINAR FINAL EXAM -
AGGREGATES AND MASONRY QUESTIONS &
CORRECT ANSWERS LATEST 2025
Walls constructed of masonry may be - ANSWER-1) Structural/Load-
bearing/Exterior walls
2) Non-structural, such as partition (interior) walls
3) Non-structural, such as veneer walls
partition walls - ANSWER-Non-loadbearing wall's that subdivide areas of a floor
veneer walls - ANSWER-non-loadbearing walls used for aesthetic
Good PHYSICAL properties of Aggregates - ANSWER-size, shape, texture, specific
gravity, etc.
Good CHEMICAL properties of Aggregates - ANSWER-reactivity, as in resistance to
chemical attacks
Good MECHANICAL properties of Aggregates - ANSWER-impermeability, volume
stability, hardness, toughness, soundness, porosity, etc.
T/F
For PCC :
, Rounded and smoothed textured coarse aggregates are better than Angular and
porous textured aggregates - ANSWER-True
T/F
For Asphalt Concrete:
Rounded and smoothed textured coarse aggregates are better than Angular and
porous textured aggregates - ANSWER-False
T/F
For Asphalt concrete:
Angular, Rouch and Porous textured Course Aggregates are better than
rounded/smoother aggregates - ANSWER-True
T/F
For PCC:
Angular, Rouch and Porous textured Course Aggregates are better than
rounded/smoother aggregates - ANSWER-False
T/F
As the trend to use recycled concretes and crushed rocks to supply coarse
aggregate (CA) for PCC — in response to diminishing naturally available gravel
along river beds — the use of chunky but angular, and less than completely
smooth-textured CA is now normal. - ANSWER-True
