Any bids?

Good job guys ... looking forward to reading the rest of the series ...

Whew! After 30 years in construction I thought I had a pretty good handle on concrete. Now that research has begun, I'm finding out that modern concrete is really amazing stuff! LaFarge alone spends $2 million a year on R&D.

It looks as if the "history" of concrete is still being made ...

Here is one for you Kenton.

SCC-Self compacting concrete, with no need of a vibrator for consolidation.

Innovation at it best.

I had a client that is working on building and safety installations of the tailing ponds. Technical safety engineer. I will try to get some information on SCC.

Thanks guys,

Yep, self-consolidating concrete, concrete you can place at 15 below zero, concrete that can go 60' x 60' without control joints, pervious concrete that is permeable to 5 gallons of water per minute per sq. ft., concrete that grass grows through that can be driven on, concrete so lightweight that you can cut it with a saw or drive a nail into it, concrete that absorbs carbon dioxide, chocolate-flavored concrete... I've got a list of 20 different kinds of concrete. The LaFarge batch plant here has over 400 design mixes on their computer.
Everywhere I go I look at concrete, take pictures of concrete, think about concrete... concrete, concrete, concrete... I want to become the Concrete Whisperer.
