Quick Buzz Becoming the Producer Post ► Concrete from Wood!

According to the new changes on the beBee platform, a short buzz or a Quick Buzz, as named, will be distributed only to followers and won’t be shared in any hive.

If you want to share a link or a picture into a specific hive, you need to write the additional text to fulfil the minimum quota foreseen for a Producer post (200 words).

It is my first attempt at converting a Quick Buzz into a Producer post and sharing the link to my hive Interesting Engineering, Technology, and Discoveries.

The article is about a new type of concrete largely consists of wood developed by Swiss researchers of the Institute for Building and Environmental Technologies at the School of Engineering and Architecture of Fribourg. They are fabricating a load-bearing concrete in which the volume fraction of the wood is over 50 percent.

According to the head of the Institute Daia Zwicky, the new concrete-wood materials weight half the weight of normal concrete. The lightest of them even float! They also show good flame retardancy and act as thermal insulation.

It will take several years before we see the first buildings in which lightweight concrete containing wood plays an integral role in the construction. The level of knowledge required for widespread application is still too limited.

And so it goes. (Nice of y'all to notice.) So what is this Quick Buzz and where do I learn about it?

May be I was influenced by Jerry Fletcher without realizing it.

I almost thought that comment was written by Jerry Fletcher because of "So it goes." :)

Advancements take time to disseminate in the minds of practitioners dear Lada. So it goes.

Sorry for the late response. I'm in the process of relocation. My office is moving to a different location in the city, and there is a lot of work to do. Phil, all such research activities are focused on the ecological aspects and finding alternatives to concrete. This method significantly reduces the quantity of concrete. The image in the post shows the testing process of the specimen consisting of glulam beams on the bottom and the WCC layer over. Also, very interesting is how two different materials are connected together to ensure distribution of loads but also a solid connection between WCC and timber. Placing WCC as the secondary (non-structural) layer met all requirements for fire resistance, acoustic and thermal insulation. As for the lack of the interest, I have nothing more to say. If I had a time, I'd share this myself with my community on LI. Thanks for doing so.

Kevin Baker well said! Hives are for producing honey!

Although a timber floor slab is claimed to provide a better feel underfoot than concrete floor slab, I never felt the difference on my joints. I've been living whole my life in houses with reinforced concrete slabs and wood floors over. For six years now, I've been working in a 100-years old building with timber floor slabs and what I sometimes feel are vibrations. To prevent stress on joints, perhaps you can install sleepers subfloor over a concrete slab.

Lada, you provide an excellent example of leveraging the improvements to this platform to share buzz in hives via Producer. Kudos on your efforts and buzz on!

I forgot to thank you for commenting both the Quick Buzz information and the main subject of the buzz, new wood concrete material. :-) Some other research on concrete wood are conducted in Canada.

Thanks for commenting, Joanne. I'm curious to see its large-scale application.

Thanks, Chas. I don't post often, but with the new rule, I think I'll post less because it takes time to write even such small post. But when you are in Rome...... :-) By the way, why the new profile photo? Is this some form of protest? :-)

#20 Phil, something happened with my mobile and I accidentally deleted my reply to you. I write it again. Phil, you and I both are the builders. You build ships and I build buildings. So, you are more than qualified to ask questions. :-) Heavy materials like reinforced concrete require higher installation and transportation costs than lighter construction materials. As for this new type of concrete, I've read the paper mentioned at the end of the article explaining the use of wood-cement compounds (WCC) in structural elements. Combining WCC with timber for load-bearing systems creates a HYBRID structure that is strong as a structural element, merging advantages of each material (fire resistance, thermal and acoustic insulation). Because of low stiffness of WCC, the material is placed in the compressive layer of a hybrid slab to increase the stiffness of the load-bearing element. As said in the article, the level of existing knowledge required for widespread application is still too limited. It will take several years before implementation. You're right this is an improve concrete, but I see it as a large improvement towards "greener" building materials. I'm sure we'll see many more improvements in the years to come. Thank you for commenting on the subject of the post. It seems you'll be the only one. 😞

Dear Phil, you don't need to wait to see how many people will be interested in talking about the engineering aspects of the wood-concrete materials. The answer is probably, none (I still hope I'm wrong). I realized that fact as soon as I came to beBee, despite the apparently large number of users coming from the construction industry. Final confirmation of this "thesis" is my last Producer, Engineering Talks No. 1. Even people I mentioned in the post, who are the authors of some articles about construction-related topics, never joined the discussion here on beBee but reached to me on LinkedIn. I think it's the same situation with the Milos Djukic's posts on material science topics. The same is with you when you publish articles about the marine industry. But as in life I hardly give up. I still hope that at least one person close to my profession read this. :-) Hope dies last.

Glad to see you, Linda. This post is the first one of the so-called "converted" articles since the short form contents (short buzzes) can't be distributed to the hives anymore. For example, your buzz about the lecterns and trade show stands now will be distributed only to your followers. Thanks for commenting. Have a good weekend too.

#3 Thank you for the clapping hands and sharing. :-) I'll give this new form of content a try. It requires much more time than before to share articles in the specific hives. But since it is a new rule we must accept that to maintain existing groups. To build the construction community around industry-oriented hives is already a hard job on beBee. Hope this will work. :-)

Linda Adams exactlym Thanks for your support. It makes sense not to put a buzz in any hives and encourages elaborated content!

Two great advantages: a notification to your followers and an email to your followers ;)

You need to work a little bit but.. it is beautiful. You added value to the hive! When we share a link we tend not to add any value and that link is everywhere. Thanks
