Standard cement prefabricated board load capacity is a square how many kilograms, thank you
In accordance with national standards: cast-in-place cement board bearing capacity is 250 kg / square meter, prefabricated board is 200 kg / square meter.
Prefabricated floor is generally hollow board, crack is a common quality, the overall poor, the advantage is the floor thick, sound better than the cast.
Many places prefabricated boards are off, but are not forced. Or according to the actual situation around, economic conditions, the general type of building to segment the solution.
Casting is in the field of mold, bar reinforcement, watering concrete and other construction procedures to do. Compared to the prefabricated system is the overall shape, good integrity, for a pipe through, or irregular shape of the floor is still very suitable, but its processes, wet operations, the site of watering, the construction period longer The The cast-in-place slab is good and the seismic capacity is strong. Generally there will be no cracks, but thinner, if not do noise treatment, will be more noisy
