👉What is the difference between working stress approach and limit state approach?
 
🌟For working stress approach, service loads are used in the whole design and the strength of material is not utilized in the full extent.

⏺In this method of design, stresses acting on structural members are calculated based on elastic method and they are designed not to exceed certain allowable values. In fact, the whole structure during the lifespan may only experience loading stresses far below the ultimate state and that is the reason why this method is called working stress approach. Under such scenario, the most economical design can hardly be obtained by using working stress approach which is now commonly used in the design of temporary works.
 
⏺For limit state approach, for each material and load, a partial safety factor is assigned individually depending on the material properties and load properties. Therefore, each element of load and material properties is accurately assessed resulting in a more refined and accurate analysis of the structure.

⏺In this connection, the material strength can be utilized to its maximum value during its lifespan and loads can be assessed with reasonable probability of occurrence.

⏺Limit state approach is commonly used for the majority of reinforced concrete design because it ensures the utilization of material strength with the lowest construction cost input.

👉Hardened Concrete Properties

1. Strength:

The strength of concrete is basically referred to compressive strength and it depends upon three factors.
1- Paste Strength 
2- Interfacial Bonding 
3- Aggregate Strength
1. Paste strength:
It is mainly due to the binding properties of cement that the ingredients are compacted together. If the paste has higher binding strength, higher will be strength of concrete.
2. Interfacial bonding:
Interfacial bonding is very necessary regarding the strength. Clay hampers the bonding between paste and aggregate. The aggregate should be washed for a better bonding between paste and aggregate.
3. Aggregate strength:
It is mainly the aggregate that provide strength to concrete especially coarse aggregates which act just like bones in the body. Rough and angular aggregate provides better bonding and high strength.
Factors affecting Strength of concrete:
Following are the factors that affect the strength of concrete:
1. Water-Cement ratio 
2. Type of cementing material 
3. Amount of cementing material 
4. Type of aggregate 
5. Air content
6. Admixtures
1. Water-Cement ratio:
It is water cement ratio that basically governs the property of strength. Lesser the water cement ratio, greater will be strength.
2. Type of cement:
Type of cement affect the hydration process and therefore strength of concrete.
Amount of cementing material: it is the paste that holds or binds all the ingredients. Thus greater amount of cementing material greater will be strength.
3. Type of Aggregate:
Rough and angular aggregates is preferable as they provide greater bonding.
4. Admixtures:
Chemical admixtures like plasticizers reduce the water cement ratio and increase the strength of concrete at same water cement ratio. Mineral admixtures affect the strength at later stage and increase the strength by increasing the amount of cementing material.

👉Types of Joints in Construction

▶️Construction Joints
▶️Expansion Joints
▶️Contraction Joints

🌟Construction Joints

*At first, we cannot pour a larger quantity of concrete in a
single time. So at that time, a certain portion has poured as
per the recommended shuttering design and the remaining portion will be poured after a certain period.

In that, the construction joints are using to connect the old
and fresh concrete and it is also called as cold joints.

🌟Expansion Joints

*As we discussed, the construction materials are formed by the different raw material.

The concrete may shrink or
expand due to the weather condition.

*So the expansion joints gap are provided to accommodate
the movement happening by the expansion or shrinkages
and it is avoiding the disfiguration of the structure.

*Mostly the expansion joint gaps are providing in large
structure & bridge girder to spread eventual stress. The joint gaps are filled by the expansion material like fibre, bitumen or some other special material.
*Expansion joint might be provided in mid of each
span in bridges.
*The provision of expansion joints is when the
structure length exceeding 45m.
*The reinforcements should not be provided on the
expansion joint area.
*The expansion joint material will be different based on
the structure.
*The expansion joints are provided as per IS 3414.

🌟Contraction Joints

*It is another type of joints which controls the cracks
happening due to shrinkages. The contraction joints are
placed as a groove where the crack may form in concrete.
If the shrinkage crack is formed in the concrete slab then
the contraction joints prevent spreading on the other area.
*Specification The width of the groove should not be less than 5mm.
*The contraction joint depth is 1/4th of the Concrete mean depth.
*It should be placed in the weakest zone of the slab.
Another name of contraction joint is Control Joint .

Is it structural problem or just plastering cracking down ?
