Jul 10, 2020 This article presents properties of concrete using different percentage of water and sodium silicate treated saw dust as replacement of sand. Saw dust passing through 4.75 sieve was treated with water and sodium silicate for 24 h before using in concrete. Natural sand was replaced with 5, 10,15 and 20% water treated saw dust in concrete mixture.

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.

Growing Potatoes in Sand Sawdust? (plants forum at permies)
As the mulch breaks down, the nutrients percolate down into the soil. Material with a high lignin content (sawdust, wood chips, leaf mold) supports the fungus. It's that fungus that makes nutrients available and moves it around to where it is needed. Everything works together. Sand and sawdust is a start.
