Name: Nissan  Avraham
Heading: Sand Presentation
I am preparing for a presentation for the annual fall meeting of the Dallas Chapter of the American Concrete Institute. The title of the presentation will be “Manufactured Sand - The Future Fine Aggregate.?” My emphasis will be on utilizing a manufactured sand with a lower fines content (particles passing the 200 mesh) rather than the high fines content as presented by ICAR. I am looking for examples of concrete utilizing just manufactured sand and not a mix of natural sand with manufactured sand. If you know of anyone using manufactured sand to make a concrete, please let me know. As they say, a picture says a thousand words.

Any help would be appreciated.

I suggest you contact Tim Folks at Hawaian Cement. 808 483 3300. I know they use a lot of manufactured sand, they do blend some Maui Beach sand but perhaps not in all mixtures. Certainly they primarily use manufactured sand all their mixes.

Doc -

Thanks a lot. I'll give him a call next week. I'm trying to talk the ARI in sending me to Hawaii so that I can get those truly significant, everyday pictures with comments from the everyday people about concrete made everyday with manufactured sand. I did have a blast at the ICAR conference (Thanks again ARI and you're band of merry men). It was like being a kid in a candy store. Everyday there was like Christmas for me. I ran out of time to talk to everyone I wanted to and there was probably a few that wanted me to go away. Not only was there people from all over the U.S. there, I personally met and talked with people from five different countries - some as far away as Sweden and many from as close as Canada - and they all had something really interesting in their experiences and research to share that wasn't part of the structured conference.

I was surprised to see in the Aggregate's Manager's state by state summary of the USGS's findings that Hawaii actually had one sand and gravel deposit shown. I also noticed that the USGS's information is not quite accurate, as sand and gravel deposits are still shown which sell sand and gravel, but no longer mine it. There were also examples of names of quarries listed which had already changed hands twice by now. Thirdly, there were sand and gravel pits that were not shown.

It is interesting in Hawaii, that each island has a basalt that varies in characteristic's from each other. Each basalt behaves differently and each island has it's own aggregate specifications for concrete.

I recently asked one of my daughters on a proposed trip to Hawaii to go to few quarries and pick up some basalt samples and hit a few concrete projects and talk to some quality control people - she's in the pre-med program at Long Beach State and didn't sound too confident with the request.

The quest continues . . .

Jay and all,

As the sand and gravel commodity specialist I might be rather upset to find that we have inaccurate data regarding aggregate mining in Hawaii. However, I'm only mildly upset because I am not surprised. At the USGS we mainly collect information one of two ways. We send surveys to all known producers in HI. If the company sends back a reply then we assume they know what they are doing and list them as a producer. If they do not reply we check the MSHA listings to determine if they operated, how they are classified (sand/gravel OR quarry), and we use the number of manhours to estimate production. We also pick up new producers from the MSHA listings. We do call producers when we are able (its impossible for us to call over 10,000 locations each year) to clarify situations. We recently spoke with Hawaiian Cement to clarify their activities but it seems we may not have done a good job. We at the USGS are happy to have feedback on our reports and data. If Jay would like to give us his critique of the 14 operations listed in the Aggreates Atlas for Hawaii we would be happy to try to get it right for the next time. Of course, the MSHA site is not always accurate and in the future our reliance on their information can get us on the wrong track again.

Anyone out there that would like to assist us in getting it right for any state or any aspect of our publications is welcome to contact us. My email is

We really do try to keep it all straight but situations, definitions (is it sand and gravel or crushed stone, for instance, and limited resources often work against us.

I would also like to thank Jay for all his contributions to this forum. I have enjoyed the discussions and comments, answers and questions.
