Conventional concrete has a density of about 2100–2500 kg/m³, whereas light weight concrete typically falls within which density range?

1. Density is the defining property that separates light weight from conventional concrete. 2. Conventional concrete sits in the 2100–2500 kg/m³ band, dominating dead load on a structure. 3. Light weight concrete is engineered to occupy 300–1850 kg/m³, reducing foundation loads. 4. The lower density brings lower thermal conductivity and reduced air conditioning load. 5. 2600 kg/m³ and above would describe high density radiation shielding concrete, not light weight. _Source: IGNOU Concrete Technology, Unit 11 "Special Concrete" (Light Weight, Aerated, No-Fines, High Density, Fibre Reinforced, Polymer Concrete)._
