Approximately 29 bags are required for 1m3 of cement.

### What happens if you put too much cement in concrete?

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.
