LECTURE 2

 Concrete

The mixture of cement, water, and aggregate

  

Cement: (clay+cracked limestone+iron ore+ sand+(Heat)+Gypsum

Drinking water: used for giving adhesive character.

Aggregates: ashes, perlite

Concrete can be made and formed: Cast in place-Pre-Cast

Vibrator: for compress concrete

Concrete Central.

Transmitter: mix the concrete

Glaze: smooth the surface

Lento: 

Concrete: Rigid, Brittle; do not show plastic deformation.

 

Aerated Concrete: Lighter, better in insulation.

Lightweight Concrete:

non-load structure

can be used in insulation and acoustic

-Polymer Concrete, Fiber Concrete

The function is to increase tensional strength.

Reinforced concrete: use with steel

Shotcrete concrete: Sprayed: tunnels, pools

Types of Concrete:

Vacuum Concrete: Strength is higher, better surface quality.

Litracon transparent concrete:
