Hello, friends in this article I am going to tell about “Difference between mortar and concrete” so, read carefully to get full knowledge about it.
A) Concrete:- The concrete is a mixture of cement, sand, crushed rock, water, which, when placed in the skeleton of forms and allowed to cure, becomes hard like a stone.
A cement concrete has attained the status of major building material in all branches of modern construction because of the following reasons.
- It can be readily moulded into durable structure items of various size and shapes at practically no considerable labour expenditure.
- Able to done check the properties of cement concrete within a wide range by using appropriate ingredients and by applying special processing techniques, mechanical, chemical, and physical.
- This is possible to mechanise completely it’s preparation and placing process.
- It possesses adequate plasticity for mechanical working.
Different Properties of concrete are given below;
- It is high compressive strength.
- It is free from corrosion and there is a no appreciable effect of atmospheric agents on it.
- Make become harder with age and the process of hardening continues for a long time after the concrete has attained sufficient strength. It has this property of concrete which gives a distinct place among the building materials.
- This is proved to be more economical than steel. It is due to the fact that sand and crushed rock, forming the bulk of concrete, to the extent about 80 to 90%, are usually available at a moderate cost.
- This binds rapidly with steel and as it is weak in tension, the steel-reinforced is placed in Concrete at a suitable place to take up the tensile stresses. It is term as the reinforced cement concrete.
- it has a tendency to shrinks when there is initial shrinkage of concrete which is mainly due to loss of water through forms, absorption by the surface of forms etc.
- It is a tendency to be porous. It is due to the presence of voids which are formed during and after it’s placing.
- It forms a hard surface, the capacity of resisting abrasion.
- This, it remembered hat apart from other materials, concrete comes to the site in the form of raw material only. its final strength and quality depend upon the person who handles it.
Following are the material required for making concrete.
The different types of concrete are given below:-
1) Waterproofing cement concrete.
2) Coloured concrete.
3) Lightweight concrete.
4) No fines concrete.
5) Pre-cast concrete.
6) Ready-mix concrete.
7) Transit-mix concrete.
We Have discussed about concrete in Difference between mortar and concrete. now let’s discuss about mortar.
B) Mortar:- The term mortar is used to indicate the paste prepared by adding required quantity of water to a mixture of binding material like cement and fine aggregate like sand.
The above two components of mortar, namely, the binding material and Fine Aggregate are sometimes referred to as the matrix and adulterant respectively.
Types of mortar based on different purpose;
1) Bulk density.
A) Heavy mortar.
B) Lightweight mortar.
2) Kind of binding material.
A) Lime mortar.
B) Surkhi mortar.
C) Cement mortar.
D) Gauged mortar.
E) Gypsum mortar.
3) Natural of application.
B) Finishing mortar.
4) Special mortar.
A) Fire-resistance mortar.
B) Lightweight mortar.
C) Packing mortar.
D) Sound absorbing mortar.
E) X-ray shielding mortar.
Properties of good mortar are,
- It should be capable of developing good adhesion with the building unit such as brick, Stone etc.
- It should capable of developing the designed stresses.
- It should be capable of resisting penetration of rainwater.
- It should be cheap.
- It should be durable.
- It should be easily workable.
- It should not affect the durability of the material with which it comes into contact.
- It should be set quickly so that speed in construction may be achieved.
- The joints formed by mortar should not develop crack and they should be able to maintain their appearance for a sufficiently long period.
Following are the uses of mortar;
- To bind the building unit such as bricks, stone etc, into a solid mass.
- To carry out pointing and plasterwork on exposed surfaces of masonry.
- To form an even and soft bedding layer for building units.
- To form joints of pipe.
- To improve the general appearance of the structure.
- To prepare moulds for coping, corbels, cornice etc.
- To distribute uniformly the superincumbent weight from the upper layer to lower layer of brick or stone.
- To hide the point of joint of brickwork and stonework.
- To fill-up, the cracks detected in the structure during the maintenance process, etc.
Following are the usual test for mortar,
1) Adhesiveness to building unit.
3) Tensile strength.
So, friends, I hope this articles on” difference between mortar and concrete” remains helpful for you.
