What is bleeding in concrete?
Bleeding in concrete is sometimes referred as water gain. It is a particular form of segregation, in which some of the water from the concrete comes out to the surface of the concrete, being of the lowest specific gravity among all the ingredients of concrete. Bleeding is predominantly observed in a highly wet mix, badly proportioned and insufficiently mixed concrete. In thin members like roof slab or road slabs and when concrete is placed in sunny weather show excessive bleeding.Due to bleeding, water comes up and accumulates at the surface. Sometimes, along with this water, certain quantity of cement also comes to the surface. When the surface is worked up with the trowel, the aggregate goes down and the cement and water come up to the top surface. This formation of cement paste at the surface is known as "Laitance". In such a case, the top surface of slabs and pavements will not have good wearing quality. This laitance formed on roads produces dust in summer and mud in rainy season.
How do reduce density of concrete?
Add ballast that is less dense than the gravel/sand in the concrete such as LECA (Light Expanded Clay Aggregate).
Why do you dress a bleeding wound?
To reduce bleeding if you apply a pressure dressing. And in any case, to reduce contamination of the wound.

Does putting ice on a cut stop the bleeding?
No. It will reduce swelling only. Pressure will stop bleeding.
Definition segregation and bleeding concrete mixture?
The separation of constituents in a heterogeneous mixture creating a non-uniform distribution of concrete mixture.
Can a concrete wall 20 feet in front of an antenna reduce signal?
Yes. . it is concrete. . and it is close. . ever driven through a tunnel, even a short one, and had problems with radio reception. So yes. . a concrete wall could reduce signal

What was bleeding thought to have done in the middle ages?
Reduce swelling, inflammation, and draw poisons from the blood. It was also thought to reduce fever.
How does elevating reduce swelling and bleeding?
Elevating a limb for example helps reduce swelling & bleeding because of gravity. Putting your leg or arm up enables gravity to help keep fluid from accumulating there. Likewise, it makes it harder for your blood to get to that part of your body...less blood means less bleeding.

Why do you need to hold your arm high when it is bleeding?
To reduce too much blood loss.
