Floor System Flashcards
High-mass floor system include:
Concrete slab-on-ground
Suspended Slabs or Precast Concrete Beams
Lightweight Suspended Concrete Floor Systems
Compacted Earth, Flagstone or Rock
This is the most common high-mass floor system.
Concrete slab-on-ground
These can be used with lightweight infill and concrete topping.
Suspended Slabs or Precast Concrete Beams
Floor panels, or thin poured concrete slabs on permanent formwork, supported on floor joists
Lightweight suspended concrete floor systems
These may be competitive in cost with the conventional timber and steel framed floors, and can reduce site impacts where a slab floor is preferable to a lightweight floor.
Lightweight suspended concrete floor systems
This is less common but effective when properly designed and built for climate and site
Compacted Earth, Flagstone or Rock
Such systems have either low or no embodied energy and minimal transport impact
Compacted earth, flagstone or rock
AAC meaning
Autoclaved Aerated Concrete
It is made with fine aggregates, cement, and an expansion agent that causes the fresh mixture to rise like bread dough
Autoclaver Aerated Concrete (AAC)
This type of concrete contains 80% air
AAC
This is less common but is effective when properly designed and built for climate and site.
Compacted Earth, Flagstone or Rock
Advantage of AAC
Construction flexibility
Durable anf dimensional stability
Fire resistant
Light weight
Dimensions of AAC
Height: 8 in
Width: 24 in
Thickness: 4, 6, 8, 10, 12 in
Specialty shapes of AAC
U shaped bond beam or lintel blocks
Tongue and groove back blocks
Cored blocms
What type of finish is specifically made for AAC? Also, they are polymer-modified plasters that seal against water instrusion yet allow moistyre vapor for breathability
Stucco-type finish
