What are 4 uses of limestone?
concrete , glass, cement and mortar
What is the difference between laen concrete and ready mix concrete?
Laen concrete contains very little actual cement. Laen cement is used as a base that is found under other cements. Ready mix concrete is used for primary uses of cement structures.
What are the uses of sand stones and gravels in construction?
in asphalt and cement concrete. We can use sand ,cement and water as a mixture of mortar.
Why do engineers use reinforced concrete?
Concrete is a material which is extremely effective when loaded in compression, yet performs poorly when loaded in tension. Steel on the other hand is quite effective in tension. Reinforced concrete uses steel bars wherever the concrete is loaded in tension in order to increase its capacity.
What is the full meaning of B R C in construction and uses?
I gives overall strength and reinforcement to slub concrete
What is a sentence for iron?
I had better iron these pants! Reinforced concrete uses iron bars for strength. Let's try to iron out our differences.
What is asbestos cement in technical terms?
Fibre reinforced cement board is a better descriptor. Asbestos has a bad press recently, but glass fibres are an adequate substitute provided one uses an alkali resistant glass.
What stronger brick or cement?
http://simscience.org/cracks/advanced/concrete2.html A common mistake people make is to use the words cement and concrete interchangably. It is important to remember that cement is only a component of concrete and concrete is the structural material. The cement used in concrete is not used as a building material because it would be too expensive and not as strong as concrete. So when you see a parking garage, a driveway, a sidewalk or a road remember it is made of concrete, not cement. And, by the way, that funny looking truck is a concrete mixer, not a cement mixer! But, if cement is not concrete, then what is it? Cement is a general name for a material that binds other materials together. Yes, it is another name for glue. There are many materials which we would classify as cements and they are usually identified with certain uses, and can produce different types of "concrete". The type of cement used to make the riding surface of some of our roads (blacktop!) is called asphalt cement. It is a petroleum bi-product, and it binds rock into the road material we call asphaltic concrete.
What are the three main uses of limestone?
Road gravel or base material, source of agricultural lime, concrete and cement ingredient.
How does the construction industry contribute towards carbon dioxide emission?
The construction industry uses large quantities of concrete, which is manufactured from cement. Cement manufacture is a significant source of carbon dioxide emissions.
Weight of reinforced concrete?
The weight of reinforced concrete varies depending upon the mix type. The engineering industry typically assumes a weight of 145 pounds per cubic foot (pcf) and most often uses 150 pcf for structural calculations. Note that this is for standard cured reinforced concrete. Lightweight concrete is generally taken as 110 to 120 pcf, again, depending upon the mix design. The fact that there is sometimes more or less steel reinforcement within the structural member is ignored.
