Hello, I'm Gareth Griffith-Jones. I wanted to let you know that I undid one or more of your recent contributions to Roman concrete because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. — &#124; Gareth Griffith-Jones &#124; The Welsh Buzzard&#124; — 16:51, 31 May 2015 (UTC)
