Hello. This is my first post on this site. I have quite enjoyed reading the information from subscribers.
I have tried to find an authoritative answer to a simple question. How many bags of, say, 20kg Goliath portland cement per cubic metre of concrete made at a rate of both 6;1 and 9;1.
It amazed me when I asked 2 professional concreters this question when they answered "I don't know - all I do is call for a truck load".
Well I only have a small size pad to make but I need to order my sand and cement bags.
I am building a pad for a barbecue area 3 metres x 2 metres x 90mm with light reo.
regards
David
