Different Grades of Concrete, Their Strength and Selection

Dec 14,  · So, suitable grade of concrete can be selected based on structural requirements. Nominal mixes for grades of concrete such as M15, M20, M25 are generally used for small scale construction. Large structures have high strength requirements, thus they go for higher grades of concrete such as M30 and above. The mix proportions of these concretes

Prestressed Concrete Bridge - an overview | ScienceDirect

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

Difference in quality of construction between red bricks

DIFFERENCE: AAC block is eco-friendly whereas conventional red brick is not. On AAC block dead load on the structure is low which reduces the consumption of cement, steel, and water. Whereas using red clay brick there's a heavy dead load on the structure. AAC blocks emit less heat in the atmosphere due to less use of cement, steel, and

What Are Concrete Expansion Joints? Do You Need Them?

Concrete Expansion Joints are basically a space or gap between two sections of a concrete slab. This gap allows each slab of concrete to move independently and freely from one another. You may think concrete is so hard that it doesn’t move but that’s not the case. Concrete routinely expands and contracts as it changes temperature.

Difference Between Pre-tensioning And Post-tensioning

Difference Between Pre-tensioning And Post-tensioning: Pre-tensioning and Post-tensioning methods are used under the pre-stressing process which has few edges over the orthodox non-stressed structures like greater span to depth ratio, higher moment, and shear capacity. These methods are generally adopted in the making of PSC girders, sleepers, etc.

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3-5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.
