Different Grades of Concrete, Their Strength and Selection ...
Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.

7 Concrete Durability Factors to Consider
The first use of modern concrete in bridges was in the late 1800's with the construction of the Alvord Lake Bridge in San Francisco in 1889. Nearly 130 years later, the vast majority of bridges worldwide are constructed of structural concrete. The average lifespan of a bridge ranges between 50-70 years. Many factors can influence that life ...

Foundations for Bridges (With Diagram)
Thus, by shifting the pier by 0.6 m on the high side of-the well, reduction of moment due to tilt and shift is (850 + 150) x 0.6 = 600 tm which reduces the foundation pressure by 600/50.27 i.e., 11.93 t/m 2 bringing down the excessive foundation pressure of 61.48 to (61.48 – 11.93) = 49.55 t/m 2 as obtained above.

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.
