In order to evaluate the suitability of nonpotable water available at the job sitefor mixing concrete, six standard mortar cubes were made using that waterand six others using potable water. The cubes were tested for compressivestrength after 7 days of curing and produced the loads to failure (in pounds)shown in Table P6.22.a. Based on these results only, would you accept that water for mixingconcrete according to ASTM C94?b. According to ASTM C94, are there other tests to be performed to evaluatethe suitability of that water? Discuss briefly.
