1-2 ft per inch of thickness if it is outside and loaded(street with buses or trucks etc)
4-6 ft per inch of thickness if it is inside and unloaded(smaller cycles of temperature change

What is clay slab?
a clay slab is a slab made of clay
What is the difference between one way slab and two way slab?
when l/b ratio more than or equal to 2 then slab is designed as one way and when l/b ratio is less than 2 then slab is designed as two way.
What are the disadvantages of flat slabs?
In flat slab you save time formwork of beams.
If you painted your cement patio with a concrete paint but want to tile over it will the mortar stick to the oil-based paint?
I recommend consulting the flooring manufacturer, however, my experience suggests that the application you describe is an acceptable risk. Adhesion of floor tile to grout is more important than the grout's adhesion to the painted concrete substrate. Uniform stability is very important, and you have that with your painted concrete slab. When I had my tile done, the company used a primer to rough up the smooth surface.
What is the slab method in pottery?
The clay is rolled out like pastry into a flat slab. Then these slabs are cut, joined, curved and shaped to form the pot.
How many square feet of concrete slab can be poured without control joints?
15
What is the maximum aggregate size allowed in concrete slab that is 6inches thick?
2" based strictly on the slab thickness. However, it may be governed by form spacing, rebar spacing or rebar clearance to the forms.
Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
Is cracking at joints acceptable after new pour of concrete?
Cracking at expansion joints is always acceptable and is the reason for the joint itself. There are two kinds of cracks, pretty ones and ugly ones! Ugly ones are random cracks where the concrete relieves itself from drying shrinkage in a random location within the slab of concrete which is normally not appealing to the eye. Expansion joints are placed at predetermined intervals within the slab where random cracks are weakened planes in locations where cracking is predicted prior to fresh concrete placement. All concrete shrinks when it dries, the larger the slab, the greater the overall shrinkage. When the tensile strength of drying shrinkage exceeds the tensile strength of the concrete, cracking will occur. Lets just hopes it cracks in a spot where we planned it instead of a location where didn't. By the way, joints should be cut at least 25% of the depth of the slab.
What difference suspended concrete slab between unsuspended concrete slab?
Supended slab are slab not sit on the ground directlySuspended slab is a slab supported by beams.
When was Slab-O-Concrete created?
Slab-O-Concrete was created in 1994.
Can you pour a concrete slab onto another concrete slab?
No. Concrete won't bond to concrete. It will end up cracking.
If using composite metal floor deck. what will be the spacing of 12mm diameter deformed bars for 7x7 meter concrete slab?
5.33 is the weight of 12mm dia. bars.
What is a raft slab?
Also reffered to as 'slab footing' and it consists of concrete footing beams integrated into the concrete floor slab.
How big can a floating concrete slab be?
no matter how big the concrete slab is, it will never float
What are stress cuts in a concrete pad?
stress cuts also known as relief cuts make weak points in a concrete slab to allow for expansion and shrinkage cracks. Bascially, a concrete slab is going to crack and these cracks control where those cracks occur.
