    A new method is described for the reconstitution of cement-treated specimens of sand and silt for laboratory strength tests. Saturation of the slurry mix is attained through boiling the sand fraction at atmospheric pressure, boiling the silt fraction at a pressure that is reduced to a vacuum of 80 kPa, and mechanised blending of cement into the combined soil fractions in a rigid-walled former that is subjected to the same vacuum pressure. Reproducibility of the method is demonstrated from tests on four identical homogeneous specimens that yield a very narrow range in water content, bulk density, and unconfined compression strength. It is further evident in the trend of increasing strength with normalized cement content in those data.
