Abstract
  • Purpose and scope of study. Inquiries from farmers, county agents, and contractors requesting information concerning the use of sawdust as an aggregate in Portland cement mortar or concrete have been received frequently enough to draw attention to the problem. This work was under· taken witk the view of obtaining data regarding the properties of the cement-sawdust and of the cement-sand-sawdust systems, with particular interest centered on the compressive strengths and thermal conductivities. Various admixtures were tried with the hope of increasing the strength or of reducing the cement requirements for a given strength. But in no case was the sawdust "processed" or "treated" other than in mixing.
