Concrete. Ha-25,30,35. Aggregate<15 mm. Steel. B500T welded mesh, 5 to 10 mm diameter. Reinforcements on edges and corners.
· Standard measures (Size limits given by the load capacity of the available machinery: <1000 kg standard tower crane; <5000 kg mobile crane)
Thickness > 12 cm in structural panels. 8- 12 m in non-load bearing panels.Height < 3.50 m normal truck; < 4.00 m
truck loader. Length < 13.50 m normal truck
· As an example, a 8cm thick panel would weight 200 kg / m2. Considering a 3, 50 m. height and a 5,00 m. length, the total weight would be 3.50 x 5.00 x 200 kg / m2 = 3.500 kg

2.3. Concrete sandwich panels· Same materials, but including an insulations, usually extruded polystyrene.· Standard measures
Thickness 6+10+6 (300kg/m2).Height around 2,00mLength 3,00 to 10,00m
· Total weight would be 1.800 to 6.000 kg/unit
