- Mixing mortar for Cordwood Construction at a workshop in Manitowoc, Wisconsin. First we mixed with shovels and hoes, next we learned to use a small bucket or can and finally a mortar mixer.
When working solo or in a small group, you can dry mix the batches and store in lidded 5 gal pails. That way you only need to add water to get a new batch ready and each batch has the exact measurements.
Absolutely! That's how I would do it. Make a batch, pour it in the wheelbarrow and then mix a dry batch, then go build the wall.
I have white oak , Virginia red cedar , and Texas Elm , does the wood have to be dry , or can you use green wood. E, Texas
The wood needs to be dry to 12% moisture content. The best wood for cordwood is softwood. So the cedar would work well.
Acho incrível agente pedir uma ajuda e ninguém nem falar com vc . Por isso q,o planeta tá dessa forma. As pessoas não querem mudar o mundo somente sua casa seu quintal sua vida
I agree. We are hardwired to take care of our families first and then give to those in need.
Sr.buenas tardes !!! Lo felicito,...consulta, que funcion o finalidad cumple el acerrin en la parte media ??
¡Hola! la inclusión de aserrín (normalmente cedro) proporciona un aislamiento eficaz. ¡espero que esto ayude!
Good lord...Leave to a yankee to complicate making mud.
Do you know if there are going to be any wisconsin workshops like this in 2021 or 2022?
At the present time there are no workshops in the works for 2022. Check the Workshop menu at www.cordwoodconstruction.org in January/February 2022
im thinking about building a 8w x 12L shed out of cord wood. walls would be 6ft high and to the pitch would be a total of 8. how much material would i need for this project. and do you strip the bark off of your wood or can i leave it on there?
I can't tell you how much you need, but I can tell you to strip the bark and get the cambion layer under it off the wood too. If you don't you'll be inviting insects and fungi's.
Take the bark off as soon as possible when it is in 8 foot lengths. calculate th sqare footage of your walls. Divide by 32 and the number you get is the number of single cords you need. 100 sq. ft. of wall ='s 3 single cords (8' x 4' x 16").
Is this building at someones private house or in a public area that I could go and look at? I live near Manitowoc.
This Tool Shed is on private property. Sorry, it is not available for inspection.
How much water is for this ratio?
About 4 liters, depending on the wetness of the sand and the sawdust.
What is Portland?
Portland is Portland Cement, the glue that holds this altogether.
@@CordwoodConstruction20 and what Lime "S" is? I live in Poland and any Lime S is electric scooter ;-)
@@IvIachine Type S Hydrated Lime for Cordwood Construction
www.cordwoodconstruction.org It is very important to find your source of Type S hydrated lime BEFORE you start to build. Some building supply stores will have to order it. It is also called Mason's Lime, Miracle Lime and the S stands for SPECIAL.
• Adds workability and plasticity (sticks together better)
• Whitens the wall
• Allows for a slower set and cure rate
• Superior bonding
• Seismic resistance
• Reduces pitting, popping, water retention and efflorescence (powdery flaking)
Here is Cordwood Construction's favorite mortar mix for a non-load bearing wall. We do not suggest you use cordwood for load bearing purposes, but rather use a framework for your cordwood infill. You can even "hide" the posts within the infill, if you so desire.
• 3 parts masons sand
• 2 parts soaked & drained coarse softwood sawdust (chainsaw chips)
• 1 part Portland Cement
• 1.5 parts Type S Hydrated Lime
This mix has withstood the test of time in all our cordwood buildings, some of which are over 40 years old. There is no degradation of mortar or wood. If you build using Best Practices with cordwood you should have the same result.
Mortars made with Type “S” hydrated lime exhibit excellent handling and workability while in the plastic state. These mortars also impart low water penetration or leakage to the finished product along with superior unit bonding and seismic resistance. Most public and government building projects specify such “Lime-Portland” mortars because of these performance benefits. Type “S” hydrated lime is also one of the main ingredients in stucco and interior finish plasters. The physical characteristics of the lime are important to the handling and application during construction and the quality of the finished product. Lime with high plasticity and purity meeting ASTM C-206 will make application easy and avoid long term issues such as pitting and popping of the finished product.
@@CordwoodConstruction20 thanks a lot 😉 I do really appreciate that 😉

Why you do not use clay?
The are 5 basic options for cordwood mortars and Clay (or cob--clay, sand, straw) is one of the options. We use an 11% mix of Portland and Type S Lime to make the mortar more pliable and last longer. Clay doesn't work well as an insulator in our cold climates. You can also choose Papercrete mortar, Lime Putty mortar, cellulose mortar or the traditional one used in this video.
Cordwood Construction does it write in your book?
@@viktormironov5088 Yes, my book Cordwood Construction Best Practices gives details on all 5 mortar mixes. cordwoodconstruction.org
