———with as little water as possible to give a stiff, “no-slump” concrete-——
ping for our resident concrete man
He finally gets around to the water, an ingredient unmentioned in the piece earlier.
Abram’s Law: Within the limits of workability, the strength of concrete is inversely proportional to the water cement ratio.
No slump concrete as produced by the Romans cannot be delivered in today’s market in transit mixers and placed into forms. A water to cement ratio of .25 does not contain enough water to allow super plastizers to produce a 4” slump for “pouring” when used, the strength and durability is lost.
WOW I did not realized anybody would consider me the resident concrete man around here.
Well honestly I do know something as I have been a concrete batch plant supervisor for 16 years now.
In its pure simplicity concrete is just simply amazing, a true gift from god that without it who could say how the advances in society would have evolved?
Yes I still deliver concrete, work this season has been brisk for me in Alaska and the pay quite good. We have downsized our workforce so on many occasions the minimal amount of drivers available are often called to work longer hours.
I love being a concrete mixer driver and fortunately all my delivery area is around Wasilla Alaska, I have been to Anchorage and I hated every minute of it.
