Using the design of experimental planning to control mixing tools in making soil - cement columns

Abstract

Controlling mixing tools in cement deep mixing is a complex problem
with two major elements being machinery and human. When the
machines are in operation, the appearing drags constantly change.
However, when making soil – cement columns, this phenomenon is
ignored. Therefore, the problem leads to irrationality in machines’
productivity, quality, power and durability. Solving this matter requires
a very large expenditure. By using the theory of experimental planning
combined with a mathematical control program, it is possible to achieve
more appropriate usage of the machines, thus improving the usage
effectiveness.
