Chapter 8, Problem 8.17QP
A severe weathering clay brick was tested for absorption and saturation coefficient according to ASTM C67 procedure and produced the following data:
dry mass of specimen = 2.186 kg
saturated mass after 24-hr submersion in cold water = 2.453 kg
saturated mass after 5-hr submersion in boiling water = 2.472 kg
Calculate absorption by 24-hr submersion, absorption by 5-hr boiling, and saturation coefficient. Does the brick satisfy the ASTM requirements?
