Can I just use cement on its own?
Cement mixed with water alone creates a grout which can be used for repairing any damage on concrete structures. This cement-based grout mix is also used in situations where normal concrete won’t work, such as underwater concreting.
Should I use concrete or cement to fill a hole?
Most holes can be fixed with a quality mortar mix, although you should use one with a crushed stone aggregate to fill holes over 1 in (2.5 cm) deep. Treat holes as soon as you find them so you can prevent water and rodents from further damaging the concrete and getting into your home.
Can I mix concrete with sand only?
Can I make concrete with just sand and cement? No, you can’t make concrete with only sand and cement. Concrete isn’t considered concrete without aggregates like gravel and stone. It’s the aggregates that contribute to concrete having high strength.
Does more water make cement stronger?
The increased water leads to a higher water-to-cement ratio. When excess water creates greater spaces between aggregate materials, the voids fill with air after the moisture evaporates. The resulting inadequate compaction reduces the concrete’s strength.
Is pure cement stronger than concrete?
Let’s start with the basics: concrete is significantly stronger than cement. Cement is a durable material in its own right, but it simply does not compare to concrete. That’s why cement is usually used for smaller, more decorative projects.
Is cement alone strong?
No pure cement is not stronger than concrete as cement is only binding materials which bind aggregate and sand with the help of water. If alone cement is used it will shrink and has no compressive strength for which concrete is known for. Pure cement is actually a component of concrete.
How do you mix concrete to fill holes?
Quote from the video:
Quote from Youtube video: And a pre-mixed tin of resin and curing agent make a well in the aggregate. And pour the premix tin into the well making sure you drain and scrape as much of the contents out as possible.
Can I use mortar to fill a hole?

Quote from Youtube video: Add. The dry mix into the mixer. And allow the mortar to mix for about a minute. Then add the remaining water as necessary. Continue to mix for three to five minutes.
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.
How do you make dry concrete mix?
For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used. Measure around half of the cement, sand and aggregates (for a concrete mix only) you’re going to mix. Using half now will prevent the mix from drying out before you get chance to use all of it – you can mix the other half later.
Can you mix concrete in the hole?
Fill the hole with Fast-Setting Concrete up to 3 to 4 inches below ground level. Pour about a gallon of water per 50 lb bag into the hole and allow the water to saturate the concrete mix. Wait about 4 hours to begin constructing your fence or applying heavy weight to your post.
Does concrete harden without mixing?
Fast-setting concrete is ideal for setting posts because there’s no mixing—you simply pour the dry concrete from the bag right into the hole, then add water.
How do you mix concrete without a mixer?
Quote from the video:
Quote from Youtube video: Push a little hole in the center of the concrete mix. Here. I have a bucket that I pre measured by what the instructions said for mixing it's got a gallon a half of water for this 80 pounds of mix.
