School me on sands and what you use. I want to stock up for winter and need to start looking at Super sacks by the ton. How graded is concrete sand when you buy it off a pile and load it with a front end loader? Yes I know mine is different than yours, but how are each clasified  and what should I be looking for in a good sand?

I buy concrete sand from my local quarry. I usually buy 5 ton at a time and pick it up with my dunp truck. The concrete sand I get is very well graded from fines up to about 1/4' or so. I have done a lot of pours with concrete sand only with great success. Another thing I have found that works well is a stage 2 leveling sand from lowes. It is intended for paver bases but works well in the mix. It also works very well for a stiff hand packed type of mix. It has fines up to about 3/16' stones. I think I pay 2 or 3 dollars per 50 lb bag. I am going to buy what they have left hopefully for a deal since they don't stock it after fall. One other thing if you buy concrete sand from a quarry and store it outside cover the pile with a water proof tarp of some kind. This will keep the rain and snow from washing away all the fine sand and leaving you with only the larger stones.
I used all purpose sand from Home Depot. Now I Buy 50lbs. bags of "concrete Sand" from a local mason supply at about 3 dollors a bag. My shop is small so I buy it as needed. Not alot of room for storage. it has fines up to about 3/16ths. The only problem I run into is water content. The sand is never dry so I need to be careful. I usually put in a bit less of my calculated water and if its too stiff I add a plasticizer. Probably not the best approach. if anyone has any other suggestions that would help, I'm all ears.
I would take 300g of sand and weigh it, then cook it in the microwave until dry then weigh again. It only takes 5 minutes, but it is better than guessing when the mixer is running. You will be amazed at how much water sand can hold!
Interesting. So weigh about one lb of sand, cook it, the re-weigh it therefore subtracting the water weight. I guess I would need to do that just before each pour as the water content would be different all the time. My last pour i used 64oz. less water in each batch then I had calculated. That's from about 61lbs. of sand per batch. Thanks for the tip.
What is the maximum amount of moisture that concrete sand can hold?? 2% of its weight, or more?? Just courious.
more important than "my sand is different than your sand"... is what do you want to do with your sand? gfrc, scc, hand pack, ecc, different sand for different purpose... a broad purpose sand? Generic concrete sand is ASTM 33. pretty standard across the board as far as I understand.
I use graded sand in bags. It is spherical, dry and almost dust free. There is no guess work needed on water content.

Anyone know where to buy white silica sand?
I've tried but could never source it. Like many others, I use white marble sand. Marblemix is quite common. You can google it and/or refer to another thread on it here: http://concretecountertops.ning.com/forum/topics/white-concreteglas...

Awesome, thanks for the info! Googled it and found it here: http://www.lanemt.com/ Not sure yet how to get it local (I use such small quantities) but good to know.

I have recently sourced silica sand locally from Quikrete. I have to buy it through a local lowes store. It is sold as "Pool Filter Sand" I don't know if it is white ( since I have'nt bought any yet ) but the spec sheet says it is a dry silica sand with US Sieve Size 20-40 and Particle size (0.85-0.425 mm)

Yea, regular #30 silica is readily available at all the big box stores, bulding/masonry supplies, etc. It's white silica that I haven't seen nor pursued that much. thanks
