Compressive strength of brick made from mud, sand and cement : Compressive strength :
Compressive strength of mud clay brick: 1.6 -1.9 MPa
Strength of cement-soil mortar:4.19- 6.90 MPa
Compressive strength of cement sand mortar:1.67- 4.77 MPa
My conclusion based on the research I do related to the above topic is given below;
The compressive strength of mud-brick increases with increasing cement and sand into it.
