Structural building components and method for production on the basis of laterite

A method for production of high strength structural building components, comprising preparing a moldable mixture of lime, laterite and water, the laterite comprising laterite particles containing iron oxide and silicon and aluminum, in the form of oxides and/or silicates thereof, and containing at least 8 weight percent of aluminum calculated as Al.sub.2 O.sub.3 and at least 4 weight percent of Fe.sub.2 O.sub.3, and the silicon content of the laterite including from 10 to 50 percent of quartz sand based on the weight of the laterite, the laterite comprising from 55 to 93 weight percent, the line from 5 to 15 weight percent and the water from 10 to 20 weight percent of the moldable mixture, the moldable mixture having the consistency of a free flowing mass, forming the components by pressure molding the mixture in a mold to form components which are sufficiently coherent to withstand transport, handling and stacking without damage, the pressure applied to the mixture being sufficient to provide a density in said components of 2000 to 2200 kg/m.sup.3, transporting the components to a curing station comprising an enclosure having a moisture saturated environment at atmospheric pressure and curing the pressure molded components at atmospheric pressure in said moisture saturated environment at a temperature between 70.degree. C and 100.degree. C, the curing being continued until the components attain a compressive strength of at least 140 kg/cm.sup.2 and a lime (as CaO) content of less than one or two percent.
