Abstract:

Several variable producing inaccuracies in sand tests results were studied and recommendations are made for avoiding or minimizing these variables. A study of a fine synthetic molding sand over a wide moisture is made with other sands shown for comparison. Other points investigated are the effect of silica flour when used to close up a sand, the effect of bentonite and sand grain size on the surface finish of steel castings and the effect of the relative humidity of the atmosphere on dry sand strength.
