Carey and Sturtz (1995) and Deng and Tikalsky (2008) suggested that the workability and suitability of WFS in flowable fill depends upon its physical properties such as particle gradation, grain shape, fineness, density, absorption, specific gravity, bleeding, setting time, hydraulic conductivity, and leaching characteristics. Pure clay-based WFS samples have moisture contents of 1–4% and ...

2012-9-4 · The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than 99.7% SiO 2, with absorbed water being at a negligible level (0.1%).

How to determine AFS grading Or Grain fineness number

The AFS Grain Fineness Number (AFS-GFN) is one means of measuring the grain fineness of a sand system. GFN is a measure of the average size of the particles (or grains) in a sand sample. The optimal grain fineness number (GFN) in a sand system is determined by the type of metal poured, pouring temperatures, casting product mix (heavy vs. light ...
