Invitation to the Society of Concrete Petrographers – online meeting Wednesday December 15th at 6-8pm.

Dear Member of the SCP, As the ASTM committee meeting in December 2021 is still going to be a virtual event, it appears we still do not have the ability to meet in person for an associated SCP meeting. I would therefore like to invite you to attend a third online SCP meeting at 6-8pm (EST), on Wednesday December 15th, 2021. Over the summer online voting took place to replace the current SCP officers. The results of that vote was unanimous. So congratulations to the new President (Daniela Mauro), Vice President (Jacki Atienza) , Secretary (Ron Sturm) and Treasurer (Chris Tillema). It has been proposed that each of the new officers will provide a short introduction and presentation at this December on-line meeting. If anybody else also has a quick presentation or some interesting images they would like to share or discuss please let me know and I will try to include you in the agenda. If you would like to attend this on-line meeting and have not received an e-mail invitation with our Teams meeting link attached, please contact me at Richard.sibbick@gcpat.com and I shall send you the link. If you have any additional questions or requests please let me know. Best regards for now and I look forward to another hopefully successful online SCP meeting in December.

Invitation to Society of Concrete Petrographers on-line meeting - June 22nd..

Dear Member of the Society of Concrete Petrographers,

I hope this message continues to find you and your families well during these unusual and developing times. Although the Covid-19 outbreak does finally seem to be in significant decline, it is also clear no in person ASTM committee meeting will be scheduled for this June, so I am proposing a similar online Teams meeting to the one we held in January. On that occasion we had 5-6 short presentations and some lively discussion between about 30 attendees. The feedback I got back from that meeting was extremely positive.

I am therefore inviting you to attend another informal on-line version of our bi-annual get together on June 22nd 2021 at 6-8pm EST. We plan to again have a number of short informal presentations of 10-15 minutes followed by a few questions. I have a few semi offers to make a presentation already. If you would like to make such a presentation please contact me (Richard.sibbick@gcpat.com) and Daniela Mauro (dmauro@wje.com) before the meeting and we shall do our utmost to include you in our short agenda.

If you would like to attend this on-line SCP meeting and have not received an e-mail invitation with our Teams meeting link attached please contact me at Richard.sibbick@gcpat.com and I shall send you out that link.

I also ask that you please stay on mute during the meeting when not presenting, asking questions or having discussions. I look forward to meeting you all in an on-line manner on June 22nd, for a another hopefully fun and successful meeting.

Best regards,
Ted

Passing of Jon Asselanis

On April 29th, 2021, Jon Asselanis passed away after valiantly battling his second bout of cancer. Jon originally defeated his first round of cancer five years ago before it returned early last year.

Jon began his path to concrete petrography by obtaining his bachelor’s degree in Geology from Humboldt State University (Arcata, CA). While working as a Research Associate for the University of California, Jon obtained a master’s degree in engineering science from the University of California – Berkeley. Shortly after, Jon joined the ranks of consultants beginning with Schwein Christensen Laboratories, then Applied Materials and Engineering, and finally with Atlas Technical Consultants, formerly CEL-Consulting.

Jon leaves behind a legacy of professionalism, technical service, and numerous close relationships within the California market, as well as in the industry as a whole. Jon is survived by his wife (Tula), son (Peter), and his sister (Kara). Services are scheduled at Ascension Cathedral (Oakland, CA) and will be streamed on YouTube. The stream can be found by searching for Jon’s name and the Church’s name.
