How many bags of cement are used in a 1:3:6 ratio concrete ...

Your question is not complete because you didn't mention the concrete volume. Lets assume you want to know the number of bags of cement required for 100 cft concrete considering 1:3:6 mix ratio. Lets begin! Total volume of concrete= 100 cft. Mix Ratio= 1:3:6. Dry Volume of concrete= 1.5* Wet volume= 1.5*100cft= 150cft


How can unmixed bags of concrete or cement be stored ...

Answer (1 of 4): The only reason that cement or concrete mixes have a shelf life is that it is a pretty good desiccant. It soaks up water out of the atmosphere. You may be aware that water added to those products tends to harden them. Clearly if it is genuinely sealed, it does not absorb water. H...
