Concrete Environmental Class

3 posts in this topic

Dear Sir's 

As per soil report for   one of the project, we received the following information regarding concrete class in  below  ground: 


Based on the test results, the materials tested are classified as Design Sulphate Classes are DS-1 (Total Potential sulfate < 0.24%) and the BRE Aggressive Chemical Environmental for Concrete (ACEC) class is AC-2r (for pH <5.5). These classifications can be utilized by the structural designers for the design of concrete elements in contact with the soil. 



How exactly to inform the contractor to follow this class. 
Do we need to indicate any special cement type or special design mix? 

What exactly the above recommendation different than simply specifying the  M25 concrete. 

Please suggest any information to get knowledge on the above concrete class if possible. 

Thanks, 
Regards, 
Saikiran Gone.

      Dear Seniors, 

      What exactly difference in 


      1. BRE Aggressive Chemical Environmental for Concrete (ACEC) class is AC-2r   


      2. Normal Concrete 




      Do we need to indicate any special cement type or special design mix? 

      What exactly the above recommendation different than simply specifying the  M25 concrete. 

      Please suggest any information to get knowledge on the above concrete class if possible.

      Hi there all!
      I was working on some building project that the concrete strength of the vertical elements (shear wall and columns, which is C40 - 28 days of cube compressive strength = 40MPa) is higher than that of the horizontal members (beams and slabs which is C30). The horizontal system is solid slab with beams (depth up to 60cm). For construction purposes the contractor has proposed to use the C30 mix for column beam junctions, since it is inconvenient to prepare different batch every time u come around columns. The progress of the work is highly desirable and the contractors request is found out to be reasonable as long as it doesn't affect the structural strength of the building. ACI code (ACI-318 & ACI318R) allow to use the horizontal members concrete strength for column beam junctions as long as the strength ratio is less than 1.4, (i.e 40MPa/30MPa = 1.333 so no problem).
      I try to refer what EC will say about it but I can't find it. In order to give them decision one must refer EC as it is the code of practice for the place, so did EC address this issue in any way? If so which section? Thanks!

      Hi,
      I want to check if I understand 4.3N table right.
      Usually building has service period for 50 years and it is S4 structural class. If I use concrete class >=C30/37, then my structural class will be S3, and if additionally I will do quality control, than it becomes S2?
      If my building requires service life of 100 years, so structural class will be S6?
      And what is the meaning of 3 row in the table? Member with slab geometry? What does it mean?
