What is the mix ratio for concrete floor?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
Can you pour a concrete floor yourself?
Used for walkways, patios, and floors, concrete slabs are inexpensive to install and durable enough to last for years. When you pour your own concrete slab, you’re giving yourself a design material that is adaptive to many of your outdoor design needs, while saving money that would have been spent on a contractor.
How thick does a concrete floor need to be?
A residential concrete floor should be around four inches thick. If you plan on your concrete floors handling heavy loads, five to six inches is more appropriate. With that said, the minimum thickness of concrete flooring is around two inches, although we wouldn’t recommend choosing to go that thin.
Can 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.
What happens if you don’t put sand in cement?
If you don’t have enough paste, the concrete will dry with a honeycombed surface and may be too porous. If you have too much paste, the concrete will be easy to spread but more likely to crack when it dries. The water to cement ratio is very important when mixing concrete.
What happens if you don’t add sand to cement?
Can I mix cement with gravel only?
While sand is the most common aggregate used to create concrete, you can also mix cement with gravel, crushed stone or even pieces of old concrete. The key to success will be the ratio of the mixture.
