ABSTRACT
Abstract This paper reports about the initial steps towards the design of a practical mixer based on the new concept of kneading method. Not only the ordinary concrete, but materials like core-blend and clay-blend which are not possible to mix by conventional methods, can be mixed by the mixer developed from the new theory. The initial basic concept proposed of forming the 2n layers has been advanced to form the 3n, 4n or even more, where n is the numbers of kneading; which effectively reduces the time of mixing and increases the uniformity of the mixed materials. It is also understood that other mate rials, e.g. rocks abandoned at dam-sites, can also be used as aggregate in the concrete with less possibilities of being broken up when mixing in the new-type mixer. This study has suggested that the mixer is practicable for these materials with the enhance ment on its mechanical aspects. Keywords: clay-blend, concrete, conventional mixer, core-blend, mixing, kneading, new-type mixer, soft aggregates.
