I can’t believe I’ve been blogging for 2 years now!

I guess the title says it all. I have been blogging for 2 years! What started out as dabbling in social media has become a habit (nearly). There have been a total of 63 posts, with a cumulative readership of almost 28,000 page views. Typically I get about 200 visitors a week looking at over 400 pages. Your interest and support totally astounds me. Thank you from the bottom of my heart.

I really need to thank my employer, Command Alkon, for providing me with the opportunity to write this blog. A good portion of what I write has nothing to do with our product line, but I hope it is of use to our customers – the concrete producer.

Most of the past year’s posts have had to do with my series “Concrete Mix Design: Art and Science”. Many of those articles have had over 500 page views, with some going up to over 1,000. There has been a lot of interest in this topic. So far I have almost completed the section on proportioning aggregates. After I am through with those topics I will go into proportioning paste, followed by other topics I have in mind. Ultimately when I am finished with the series I would like to assemble it into an e-book, but who knows how long from now that will be.

In addition to the blog I have been involved in other things. Last year an article I wrote on “Profiting from Concrete QC” for The Concrete Producer was recognized as the Top Business Story by that magazine and cited as one of the 10 most-read articles for the year. Also, I have been involved in doing presentations for various association groups, including a couple of videocasts for conferences in India. And of course I have been working to improve our COMMANDqc quality control software and help our users be more productive using it. http://www.commandalkon.com/qualitycontrol.asp

Over the coming year I have a lot planned, including presentations at the NRMCA Concrete Sustainability Conference in Boston and the next ACI Convention in Washington, D.C. I’ve also launched a service helping concrete producers get the most out of their QC departments. For more information about that check out http://www.commandalkon.com/jayshilstone.asp . I’ll be teaching at our regional training conference in San Francisco in a couple of weeks. http://www.commandalkon.com/rps/sf/index.html

So once again let me thank you for reading my blog and contributing your ideas and comments. I hope that together we are making the concrete world a better place. I like to think that my father would be proud of what we have accomplished together.

Dear Mr. Jay, request you to kindly write about Bolomey curve and how to use it in mix design/aggregate proportions.

Thanks & Best Regards

I realize I have been remiss in not posting lately. Things have been very busy lately. I will try to find my notes on the Bolomey curve and post an article soon. Thanks for your interest.
