What happens if you put too much cement in mortar?
Since major force transfer in a concrete/mortar matrix is from sand-sand interaction, excess cement will turn the mortar very brittle since cement particles cannot transfer normal contact force – they are good at providing shear strength.

Is mortar same as cement?
Cement is a fine binding powder that is never used alone but is a component of both concrete and mortar, as well as stucco, tile grout, and thin-set adhesive. Mortar is composed of cement, fine sands, and lime; it is used as a binding material when building with brick, block, and stone.
