Concrete constructions without reinforcement, like other unreinforced masonry buildings, can fall short during extreme earthquake shaking.
Ensure that your Completely ready mix supplier appreciates if you will be pumping concrete. Pumping mixes require a enough amount of fines and you will find boundaries to the scale with the combination to ensure that the mix for being pumpable.
