you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
Yes, so that the concrete doesn't break or split.
Rebar is used as a tensioning device in reinforced concrete and reinforced masonry structures holding the concrete in compression.
yes
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
Lead weighs more than concrete. Lead is a dense metal with a higher specific gravity than concrete, which is a composite material made of cement, sand, and aggregates.
Because the sidewalk expands when it is warmer out, which can lead to cracking. In order to avoid this, the concrete peeps put intentional cracks in between each slab.
Concrete, lead
In Junior and Senior Infants we got concrete objects to count with.

Yes. It is a myth that a battery will run down sitting on concrete.

Concrete illustrations are used to put abstract ideas into close-up words. The concrete words could be described as tangible descriptions.
Lead or concrete are effective at shielding against gamma rays due to their density which allows them to absorb and block the radiation. Designing structures with thick concrete walls or using lead shielding in equipment can provide protection against gamma rays. Additionally, maintaining a safe distance from gamma ray sources and limiting exposure time are important safety measures.
It starts curing the second they put water in it.
Gamma radiation can only be stopped by a thick lead sheet or very thick concrete due to its high energy and penetrating ability. Lead and concrete are dense materials that effectively absorb and attenuate gamma rays, reducing their harmful effects on living organisms.
