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?

Q1: A: define the following:
Steel corrosion, seasoning, fly ash, flash point, grout
B: 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?
Some testing on fire clay brick was performed such as density, water absorption andcompression test. The result obtained has shown in Table Q2.
So Calculate the average density of brick. ?
