I worked in construction during the Summers when I was still in school. I remember that someone always sampled the concrete coming out of the truck when we poured a slab or any concrete structure. There are different grades of concrete (rated in pounds of pressure (PSI)) that are used according to the architects specifications. I believe it may have been the architectual firm that was sampling the concrete.

Rubicon,
Concrete setting times: http://powerblanket.com/2008/01/31/t...-setting-time/ and you can add accellerators to speed up the set time: http://www.fhwa.dot.gov/infrastructu...p/acclerat.htm |
