Hi, Robert.
In our last 2 batches of papercrete, we used your formula w/the
paper, concrete, lime, sand and clay. Per your suggestion it adheres
better, we do find it is sticking better to the side of our metal
barn in our two small experimental spots.
We found it fascinating that the small addition of the clay changed
the color into a bit of a natural adobe color--love it.
My question is, do you know how much the addition of the sand and
clay affect the R-value of the papercrete?
We made a second batch as above but this time added about 1.5 cups of
latex paint. Does anyone know how this affects the R-value?
Even though the two batches were poured and even tamped down next to
each other within about 1 1/2 hours or less of each other, they
shrunk away from each other, leaving a significant gap between the
two "logs" or two small retaining walls. Does anyone have an
explanation of this? Why would such a small amount of latex make
such a big difference?
