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...
The rapid advance of concrete engineering in the
West has made necessary reliable information as to the
strength qualities of the most important marketable, sands
In the eastern states, theory and practice have advanced
hand in hand, by the investigation of the constituent
materials of concrete. In the West, no...
The effect of adding a high moisture gel manufactured from a combination of konjac flour (2%) and kappa carrageenan (1%) to a reduced fat ground beef system was evaluated. Lean beef (95-10) and 50-50 fat beef trimmings were used to manufacture reduced fat ground beef patties containing konjac flour/carrageenan (K/C)...
The Asphalt Pavement Analyzer (APA) device was used to characterize the impact of various mix factors on the development of permanent deformation in dense-graded mixes given a standard compactive effort. Factors included two aggregate sizes, three VMA levels, two fines contents, three binder contents and four binder types. All specimens...
The objective of this project was to investigate the performance of three different expansive additives on the hydration properties, volume change, and stress development of Portland cement pastes and concrete.
