Concrete just isn't strong enough when it isn't reinforced internally with metal bar. They didn't have a chance.

I read an article yesterday which hinted that building codes there are just not enforced for whatever reason. I can't image a concrete code that doesn't require steel rebar. It could hold against idealistic pure compression alright but once put into tension, which is impossible to avoid as well, the concrete loses about 10 times its strength.
