The adobe reaction and the use of loess mud in construction

Adobe brick and wall constructions depend for their structural usefulness on the adobe reaction. This is similar to the pozzolanic reaction produced by the addition of siliceous material to Portland cement concrete. The adobe of southwestern USA is similar to loess. Fringe loess in arid regions (North Africa, southern Spain) gave rise to the term adobe and the constructional applications. The adobe reaction may be similar to the reactions involved in lime stabilisation of engineering soils.
