Chapter 11, Problem 10(choose chapter or problem)
The strength of concrete used in commercial constructiontends to vary from one batch to another. Consequently,small test cylinders of concrete sampled from a batch arecured for periods up to about 28 days in temperatureandmoisture-controlled environments before strength measurements are made. Concrete is then bought andsold on the basis of strength test cylinders (ASTM C 31Standard Test Method for Making and Curing ConcreteTest Specimens in the Field). The accompanying dataresulted from an experiment carried out to compare threedifferent curing methods with respect to compressivestrength (MPa). Analyze this data.Batch Method A Method B Method C1 30.7 33.7 30.52 29.1 30.6 32.63 30.0 32.2 30.54 31.9 34.6 33.55 30.5 33.0 32.46 26.9 29.3 27.87 28.2 28.4 30.78 32.4 32.4 33.69 26.6 29.5 29.210 28.6 29.4 33.2
