Calculate the load capacity of a concrete masonry wall ( length = 3.3 meters), if the units used were 15 MPa concrete block units 300x150x200 , for the following cases if the walls is :

1- Hollow, face shell width is 24 mm.

2- Fully grouted.

3- Partially grouted, where half the cores are grouted.

4.) A severe weathering clay brick was tested for absorption and saturation coefficient according to ASTM C67 procedure and produced the following data [20 pts]:  Dry mass of specimen = 2.186 kg

 Saturated mass after 24-hour submersion in cold water = 2.453 kg

 Saturated mass after 5-hour submersion in boiling water = 2.472 kg

It is required to

;- a- Calculate absorption by 24-hour submersion.

b- Calculate absorption by 5-hour boiling.

c- Calculate saturation coefficient.

Does the brick satisfy the ASTM requirement
