<<So, 2 buckets of stones + 2 buckets of sand + 1 bucket of cement + 1 bucket of water does not give 6 buckets of concrete.
Depending on the size and shape of the stones and distribution of sand sizes, there might be as little as [at a guess] 3 buckets of concrete [your mileage may vary].>>
Try that mix in a wheel barrow, you would have short of 6 buckets of slop.Step away from your educated engineer background and try mixing concrete in a wheel barrow.Throw proper proportions, listed on the bag, of rock sand and cement,as i said,<< 4 shovels of quality clean rock, 3 shovels of coarse gritty sand, 2 shovels or a bit more of cement, add water slowly and in small amounts, too much no good,..>>You mix the dry ingredients together first and the perception is an almost full wheel barrow...after adding the small amount of water , for a good mix...the perception is an almost full wheel barrow...now take that grand son and give him a practical education.
Your point about size and shape of aggregate brings to mind a SI member's post, Walt from the 90's, giving a lecture to grade school students on ""is it full yet"...Large glass jar, put in large rocks..is it full yet, smaller rocks, sand, powder then water..they got the idea...i guess.
Some of the practical answers to the everyday are not always found in higher education, bingdegoogle but by doing...elmatador eh will tell ya.<g> |
