11.5. Lightweight Ready-Mix Concrete

Try these first

1. 1.

   What are the main aggregates used in Lightweight Ready-Mix Concrete?

   Hint

   Think about common materials that are lighter.

2. 2.

   What density range does LW RMC typically fall under?

   Hint

   Recall the density range mentioned in the notes.

3. 3.

   What is the primary benefit of using Lightweight Ready-Mix Concrete?

   • Lower cost
   • Reduced dead load
   • Higher strength

   Hint

   Think about how weight impacts building design.

4. 4.

   Lightweight Ready-Mix Concrete typically ranges in density from 800 to how many kg/m³?

   Hint

   Recall the density mentioned in class.

5. 5.

   Calculate the total dead load reduction for a high-rise building using LW RMC versus traditional concrete if the total volume is 1000 m³.

   Hint

   Think about the volume and density of both types of concrete.

6. 6.

   Discuss the suitability of using LW RMC for a new building project located in a cold climate. What factors should be considered?

   Hint

   Consider both thermal efficiency and structural traits.
