Differences Between Lightweight Concrete and Normal Weight Concrete

Lightweight and normal-weight concrete each have their place, but they dry differently, and that affects moisture testing. Jason Spangler, Vice President of Sales for Wagner Meters, explains what sets them apart before you put a floor over one.

He covers:

• The main differences between lightweight and normal-weight mixes, and how the aggregate drives them
• Why builders choose lightweight concrete, including sound absorption and better insulation
• Why lightweight concrete is more prone to moisture-related flooring failures: it holds moisture longer and takes longer to dry
• How that longer drying time makes accurate testing harder, and how drill depth changes for slabs that dry from both sides
