Lightweight foam concrete wall panel fireproof testing
We have finished the full testing of expandable polystyrene sandwich wall panel reaction to fire, here's parts of eps concrete wall board fireproof testings.
The observations made during the test are follows:
10-25mins, surface exposed to the flame red hot;
65-90mins, surface exposed to the flame developed cracks, opposite side still cold;
90-120mins, surface exposed to the flame developed bigger cracks, opposite side now moderately warm;
Lightweight wall panels can be accepted by lots of countries and widely used as partition wall and external wall material.
