Two-fold sustainability - Adobe with sawdust as partial ...

The results show that about 4% sand replacement by volume produces higher compressive strength, whereas the flexural strength reduces with the use of sawdust. However, since flexural strength is not a critical property for adobe, it is concluded that replacing sand with sawdust by about 4% of volume will be beneficial.

Remove All Sanding Dust Before Finishing Wood

Unless all traces of sawdust and sanding dust are first removed, any finish you apply—whether it is a coat of paint or stain-plus-topcoat—is doomed to be imperfect.Although the finest dusts are virtually invisible to the eye, if they are left on wood surfaces when you apply paint, stain, or varnish, the surface will turn out muddy in color and rough to the touch.
