Hello
Guys need some help here,

Due to sand lorry owners strike ,thinking of going to RMC for my ground floor roofing,but again struck up to decide on which type of RMC ?

what are the pros and cons of GGBS RMC against OPC cement only RMC ?

Civil gurus ,please help me on this or direct me to a right thread to know more about it.

Thanks in advance.

GGBS WILL be ideal

Hi,
Go with M20 concrete with 150 ggbs + 150 OPC mix.
Don't wast your money with full OPC. The results for this mix itself at 21 day has given 22n/mm2 which is greater than 20n/mm2
Go with ACC or Ultratech. Don't worry about the full technicality of ggbs and opc. They are both almost the same.
