Use a higher density aggregate, or decrease the amount of air entrainment.
Concrete does not float naturally in water; it is denser than water. However, when concrete objects such as boats or platforms float on water, it is typically due to buoyancy provided by a hollow structure or trapped air pockets within the concrete. This buoyant force can make the overall concrete object less dense than water, causing it to float.
No, steel is denser than concrete, so it is heavier by volume. However, concrete can still be heavier in certain applications due to its bulkiness and ability to be molded into large shapes.
you make salt water denser by adding more salt to the water
Dry concrete has a greater density than wet concrete because the water content in wet concrete decreases its overall density. When the water in wet concrete evaporates during the curing process, the concrete becomes denser.
Dry concrete weighs more than wet sand because concrete is denser and more compact than sand, even when wet. Concrete is composed of cement, sand, gravel, and water, which results in a heavier material compared to sand alone.
you make salt water denser by putting more water or taking the salt off the salt water!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
how much do concrete layers make an hour
To make moldable concrete, mix concrete with a polymer additive that increases its flexibility and workability. This allows the concrete to be shaped and molded into various forms before it hardens.
To make concrete smooth, you can use a concrete float or trowel to level the surface while it is still wet. You can also use a concrete grinder or polisher to smooth out any rough spots after the concrete has dried.
Reinforced concrete is just normal concrete with steel reinforement placed inside.
If the correct concrete mix is used and laid properly, hot weather should not make concrete crack. Instead, it is the freeze-thaw cycle that makes concrete crack.
Commercial concrete companies make many millions/year.
