Sundar said: (Mar 28, 2013)  
Mortar: A cup-shaped receptacle made of hard material, in which ingredients are crushed or ground, used esp. in cooking or pharmacy.

Karan said: (Mar 28, 2013)  
Mortar is a mixture of cement sand and water.

And its ratio varies depending upon where it is used.

In a motor cement is a binding material aggregates gives strength and sand is used to fill the space in between aggregates and to give better finish.

Jitndrakumar said: (Apr 1, 2013)  
Cement is hardness of binding.

Shilpi Singh Rajpoot said: (Apr 7, 2013)  
Mortar is the mixture of cement, sand. Aggregate and water. It may be in different-2 ratios. The setting time of cement is minimum in all those of aggregates and that is 30 minutes. So thats why, in mortar cement is the binding material.

Jamil Khan said: (Jun 5, 2013)  
Mortar is consists of binding material, sand, and water. So we use cement mostly for paste. Because cement have cementitious property and it tightly bind aggregates.

Soubhagya said: (Jun 8, 2013)  
Mortar is used in different proportions in many applications where it is used?

Yogendra said: (Jun 27, 2013)  
Because it is binding material for making mortar or other.

Mounika said: (Jul 1, 2013)  
Cement is used as binding because it consists of chemical substances present in it.

Haryiiit said: (Jul 19, 2013)  
Cement has binding nature because of it's contents. They are Silica, Aluminium, Iron and other material like ash.

Lakshmi said: (Aug 6, 2013)  
Mortar is mix of cement, sand and water. Cement plays a role of binder by its slurry nature due presents of minerals like Al, S, ash etc while mixing with water.

Robin Sanwat said: (Aug 8, 2013)  
Mortar is mix of cement, sand and water but after adding aggregate then we can say concrete so in mortar cement is a binding material.

Jagdish Dangi said: (Sep 7, 2013)  
Definitely mortar is binding material in mortar specially cement is used for binding purpose.

Vijay said: (Sep 10, 2013)

Why use of concrete in structure?

Kavya said: (Mar 6, 2014)  
Concrete is a mixture of cement, coarse aggregates and fine aggregates (in 1:2:4 ratio, it may varies for different structures) , water.

Cement is used as binder, coarse aggregates are for strength, fine aggregates are used to fill the gaps of coarse aggregates, water is used to mix all the materials homogeneously.

Not only concrete, we can also use steel. But concrete have more resistance towards fire, and of less cost, maintenance cost is low as compared to steel so we use concrete in structures.

Disadvantage:

Steel can be reused but concrete can not be reusable.

Ram Royals said: (Mar 24, 2014)  
Mortar is binding materials mixture of cement and sand so used the cement is binding materials.

Sonam Tobgay said: (Apr 6, 2014)  
Since cement contains binding properties (when it is mixed with water the chemical process called hydration is ignited).

Sachin Kumar said: (May 23, 2014)  
Mortar - Binding material + Aggregates + water.

1. Aggregate - In Coarse form (Gitty) & In fine form (Mauroom).
2. Binding Material - Use as a Lime & Use as a Cement.

Lime Mortar - Lime+Gitty+Mauroom+water.
Cement Mortar - Cement+Gitty+Mauroom+Water.

Importance :

1. Coarse Material- Provide pore space for filling the binding material.

2. Binding Material- It bind coarse type of material and fine type of material with water.

Provide Minimum setting time (30min) for coarse & fine Material.

3. Fine Material- Some type of tiny pore space not filled so we used fine material & Provide good finishing.

4. Water- Mixing of coarse, Fine, & Binding material without water called Dry Mortar.

And then mix the water in Dry Mortar & make it Slurry Form.

Slurry mortar fix easily in pores.

5. Mortar is not reusable like brick and steel.

Suresh Babu said: (Jun 29, 2014)  
Mortar is mixture of cement, sand, aggregate and water. It may be in different ratio.

Mukkara Raviteja said: (Jul 3, 2014)  
In this type of mortar, the cement is used as binding material. Depending upon the strength required and importance of work, the proportion of cement to sand by volume varies from 1:2 to 1:6 or more. It should be noted that surkhi and cinder are not chemically inert substances and hence they cannot be used as adulterants with matrix as cement. Thus the sand only can be used to form cement mortar. The proportion of cement with respect to sand should be determined with due regard to the specified durability and working conditions. The cement mortar is used where a mortar of high strength and water-resisting properties is required such as underground constructions, water saturated soils, etc.

Gokul D said: (Jul 19, 2014)  
The properties of cement is only react with water to get harden. But other materials not react the same. So the answer is cement.

Without using cement, they should not work to cement, sand and water.

Saurabh Bidani said: (Dec 19, 2014)  
Cement - Used as binding material.

SAND - Sand is used for filling voids of coarse aggregate & increases its strength as well as durability.

SURKHI - Surkhi is used as substitute for sand for concrete and mortar, and has almost the same function as of sand but it also imparts some.

Strength and hydraulicity. Surkhi is made by grinding to powder burnt. Bricks, brick-bats or burnt clay.

CINDER - Cinder is ash. *in simple language. Having same work as sand & cinder.

Hence sand can be replaced by cinder or surkhi. *Some building codes expressly prohibit the use of cinder blocks in construction projects.

(b) They also make the concrete more resistant to alkalis and salt solutions.

Cinder : (a) Cinders have been used on track surfaces and roads to provide additional traction in winter conditions.
(b) Cinders are also employed as inorganic mulch in xeriscaping, because of excellent drainage properties and erosion resistance. In this context, they are referred to frequently with the name " lava rock".

Sand: I think sand is far matchable answer to the above question.
