They sold us a lemon. The car broke 4 months after we bought it. Had to replace the transfer case ($4,000). The roof leaked when it rained ($500). Not to mention when we first got the car, all the...
When performing temperature tests, it is important to. use a good, accurate thermometer that is surrounded. by at least three inches of concrete. Take readings. quickly, noting that small samples lose heat fast. Concrete temperatures are affected by the mix-water. temperature, aggregate temperatures, cement type. and admixture type. Optimum concrete temperatures. will aid with setting, early strength development, proper curing and ultimately aid in achieving a higher. quality concrete. Hot concrete sets up rapidly, gaining.
The thermometer is placed to provide at least 3 inches of concrete around the. inserted stem and left in place a minimum of 2 minutes and until the temperature has stabilized. Start taking temperature measurements of the concrete (per ASTM C 1064) within 5 minutes after securing the remixed composite.nserted stem and left in place a minimum of 2 minutes and until the temperature has stabilized.
