Additional information

When tested in the lab three blocks (size 40h30h20 cm) from cellular concrete to be used for masonry walls, were as follows:
Mass naturally moist state, kg 16.4 15.7 16.0
Weight of dry, kg 15.3 14.8 15.1
Weight in water-saturated state, 29.6 kg 29.2 29.8
Breaking strength in compression, kN (samples - cubes of 10x10x10 cm)
In the dry state 52 64 61
The water-saturated state 37 44 41
For reference: the true density of the material - 2.45 g / cm3
Define: Humidity (%), the average density in a natural state and dry (kg / m3), a porosity (%), by weight, water absorption and the volume (%), ratio of saturation, and it will then evaluate the frost resistance, compression strength (MPa) dry and water-saturated state, the ratio of softening material.
Create passport material and draw a conclusion about its suitability for masonry buildings.
