Concrete Density - an overview ScienceDirect Topics

9.3.1 High-density concrete. High-density concrete or heavyweight concrete is produced using special heavy aggregates (with specific gravities higher than 3000 kg/m 3). EN 206:2013+A1:2016 (2016) defines heavyweight concrete as having an oven dry density greater than 2600 kg/m 3. The density achieved will depend on the type of aggregate used.

Concrete Composition - an overview ScienceDirect Topics

In the concrete compositions, 360 kg/m 3 PC-A cement was used; the maximum grain size of the river gravel was 31.5 mm. Because a major objective was to realise highly fluid mixtures, the fresh concrete slumps were 230 plus-minus 40 mm. This resulted in a water to cement ratio of 0.32 for the mixtures containing fillers and 0.35 for the reference mixture (no filler added).

Lightweight Concrete - an overview ScienceDirect Topics

Lightweight concretes can be produced with an over-dry density range of approximately 300 to a maximum of 2000 kg/m 3, with corresponding cube strengths from approximately 1 to over 60 MPa and thermal conductivities of 0.2 to 1.0 W/mK. These values can be compared with those for normal weight concrete of approximately 2100–2500 kg/m 3, 15 to greater than 100. MPa and 1.6–1.9 W/mK.

Foamed Concrete - an overview ScienceDirect Topics

The apparent density of aerated concrete is about 300 ~ 1200 kg/m 3, the compressive strength is about 0.5 ~ 7.5 MPa, and the thermal conductivity coefficient is about 0.081 ~ 0.29 W/(m•K). The aerated concrete has big porosity, small water absorption, low strength, good insulation, and bad frost resistance, often used for roof boards and walls.
