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. via
What is the strongest concrete mix ratio?
A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In pre-mix concrete, the aggregate is already mixed with the cement. via

Why do you add sand to Portland cement?
Though water makes cement easier to pour and helps it to harden, cement and water by themselves don't hold together very well. The addition of sand makes cement more binding. Cement mixed with water and sand becomes mortar, the paste used to hold bricks together. Once you add gravel to the mix, it becomes concrete. via
How much concrete will one bag of Portland cement make?

Is it cheaper to mix your own concrete?
One of the least expensive ways to get concrete is to mix your own. You can buy bags of the mix from a home improvement store. Typically, you only have to add water for it to be ready to pour. Otherwise, you risk getting a weaker concrete once it cures, which could lead to cracks or crumbles within a couple of years. via
What are the 5 types of portland cement?
Five types of portland cement are standardized in the United States by the American Society for Testing and Materials (ASTM): ordinary (Type I), modified (Type II), high-early-strength (Type III), low-heat (Type IV), and sulfate-resistant (Type V). via
What is the difference between portland cement and regular cement?
Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver. via
