Lightweight concrete production

Potentials of the suspension mixing technology

In respect of their material characteristics, lightweight concretes with bulk densities smaller than 2,000 kg/m3 can be subdivided into the structurally dense and porous categories. Production of either of these types of concrete involves the crucial step of subjecting all their constituents (in example cement, water, plasticizer, lightweight aggregates et cetera) to a conventional mixing process. Initially, lightweight aggregates are homogenized while adding mixing water. In the second step, binder components and other admixtures are added. At this stage, care must be taken to ensure low...
