Chemistry Scientists replaced 40 percent of cement with rice husk cinder, limestone crushing waste, and silica sand, giving concrete a rubber-like quality, six to nine times more crack-resistant than regular concrete. It self-seals, replaces cement with plentiful waste products, and should be cheaper to use.

Yep, and really cracks mean nothing to engineers and the ACI, the only people who care about that are the architects that have to design around control joints.

Are you a structural engineer?

u/RicketyFrigate Nov 06 '19

Nah, but I work with them. The ACI measures concrete based on slump and compressive strength, the engineers design concrete as if it will crack regardless of how likely it will crack.

You work with a structural engineering company based out of Cincinnati? Can I ask which one? I’d like to avoid working with your company if possible. If I had to guess by your comment frequency i’d say you are a bored construction inspector, but not very knowledgeable.

It just astounds me how confident you sound but how misinformed you are about pretty much everything.

Weren't you the one that said Chernobyl had the chance of making all of Europe unlivable? I admit sometimes I get things wrong, but so does everyone else, especially yourself.
