How much sand and aggregate required 1 cubic meter of plain concrete cement?
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
What is the difference between cement and grout?
Grout is a substance that is used to fill gaps between tiles, such as in a shower or bathroom. Grout may be made of small aggregate, sand, and Portland cement. It may also be made of Portland cement or masonry cement and sand. There are many different types of cement, and these are usually used as an ingredient with which to make concrete and mortar.
What is the mixing ratio in m10 concrete?
Ration used in M10 concrete is 1:3:6 1 Cement, 3 Sand & 6 Aggregate
Why suitable coarse and fine aggregate used in the concrete ingredient?
aggregates are used to concrete for following purposes: 1.if totally binding materials like cement is used in concrete, the cost of concrete will be high which is uneconomical. 2.to prevent high shrinkage of concrete mix fine aggregates are used. 3.to increase the volume of concrete mix aggregates are used.
What are admixture?
Admixture is defined as a material other than cement, water and aggregate that is used as an ingredient of concrete and is added to the batch immediately before or during mixing.
How much sand and aggregate required 1 cubic meter of plain concrete cement?
For plain cement concrete, the aggregate used is of size 20 mm. For RCC structures, it is 40mm and for roads, it is 80mm
Is cement homogeneous?
Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
How did Thomas Edison invent cement?
He didn't. The Romans used cement and concrete (cement with aggregate mixed in it for additional strength) to build their structures over 2,000 years ago.
What is fine aggregate?
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
What is the significance of grading aggregate?
The grading of aggregate influences the mix proportions for a specified workability and water-cement ratio. Coarser the grading leaner will be mix which can be used. Very lean mix is not desirable since it does not contain enough finer material to make the concrete cohesive. The type of aggregate influences strongly the aggregate-cement ratio for the desired workability and stipulated water cement ratio. An important feature of a satisfactory aggregate is the uniformity of the grading which can be achieved by mixing different size fractions.
How do you know if your stairs are cement or concrete?
um, they'll be hard. duh. ----------------- concrete is made of cement, sand and aggregate (stone, gravel, etc) so its a redundant question. Cement by itself is not very strong, its is a binder used to make concrete. In some cases sand is also the aggregate (QuickCrete is one product name)
What substance are used to make concrete?
cement, sand, water, aggregate(small stones) or sometimes crushed rock etc..
What is dry density of cement?
The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

What is the function of gypsum in cement?
Gypsum is a mineral that contains up to 88% CaSO4.2H2O. this compound Calcium Sulphate dihydrate is responsible for retarding the setting time of cement. the action of Calcium Sulphate dihydrate is such that it inhibits the speed at which Calcite (C3S) molecules bind with water to set thus creating a cement that is workable.

What is concerete made from?
Concrete is made from cement and other materials such as fly ash and slag, coarse aggregate made of crushed stone, fine aggregate such as sand and water. The aggregates are used to form the paste, while the sand or cement keeps it from wearing out easily, and the water to make it easy to smooth out.
