Do they make some super fast drying concrete now?
Last week they were fixing some bad sections of a single lane (one lane
each direction), State highway, in a rural area. First they did the left
lane, then the right (so traffic could still use it). On Wednesday, they
removed several sections of the road (some as large as about 20X20ft.).
Thursday morning around 8 to 9 am, they poured new concrete. Around 7pm
on Thursday evening they re-opened that lane.
That's only 9 or 10 hours after the concrete was poured. I've never seen
such a thing. In fact I was almost hesitant to drive on it, thinking my
tires would sink into wet cement!!!!
I recall years ago, we had a concrete driveway poured, and we were told
to not walk on it for at least 24 hours, and not drive on it for at
least 3 days, preferably one week. I remember we waited the full week to
drive on it, and it was more like 48 hours before we walked on it.
Do they now have some new concrete that drys and sets in a few hours?
Apparently so ????? ???? ??????
What is it called?
