Model tests in laboratory using dry mixing method

To clarify the effect on strength properties and homogeneity of the cement treated soil columns the shape of the mixing tool, the lifting and rotation speed of the shaft and the immediate loading of the columns after manufacturing, has been investigated in model tests in the laboratory of Soil Mechanics and Foundation Engineering at the Helsinki University of Technology. This paper is a description of test arrangement and test procedure for manufacturing cement columns in the laboratory using the dry mixing method.
