I monitor the online discussion group firstname.lastname@example.org on behalf of several clients that are suppliers to this field. The group links artists and artisans from around the world that work at the leading edge of decorative concrete. While the collective buying power for this group is not huge, the members of the group are often at the cutting edge of innovations in concrete.
On July 18, Deborah asked for help:
I know there are issues combining concrete and glass... I want to set old bottles into bases of concrete. Will I get degradation of the concrete segment that holds the bottle? Is there a additive I can use to eliminate the problem? I do use metakaolin in my mix; will this reduce or cure the issue?Two days later, Andrew responded:
I found this great article that speaks to the problem and solves itI wrote the article over six years ago -- a reminder of the enduring value of getting published. At the time, I was a consultant to BASF, producers of MetaMax brand High Reactivity Metakaolin (HRM). The article includes a great case study and explains how HRM makes it practical to use glass in concrete mixtures. The article cites my client's brand names and includes a link to their then current website.*
with metakaolin: http://www.solutions.precast.org/precast-concrete-recycled-glass-tiles-case-study They replace up to 20% of their cement with metakaolin when using all kinds and colours of recycled glass in their concrete.
I have now jumped into the conversation. Even though I explained why Deborah would not need metakaolin for her project**, the online discussion was a chance to reiterate the key benefits of metakaolin and point readers towards my client's product.
My contribution will have high credibility among this online community as one of their own has cited my article as a great resource. This word-of-mouth, peer-to-peer communication is an invaluable addition to a building product marketing communication program.
* The link is no longer valid. Companies should periodically search the internet for obsolete links to their website. I suspect that Precast Solution would revise the link on its website if BASF requested it.
** The short technical explanation is that concrete reacts in a self-destructive manner when exposed to crushed glass. The bottles Deborah wants to do not have enough surface area to create the reaction.
