Definitions
- This invention relates to a process for the preparation of shaped articles such as construction materials, pavers and the like, in particular to a process that utilises waste and other materials such as fly ash in amounts that may constitute a major proportion of the shaped articles.
- the invention also relates to a process for the disposal of particulate waste materials such as fly ash whereby these materials are converted into a solid aggregate.
- the material will be in particulate form, usually relatively fine particles.
- the mixture of the aluminosilicate containing material, iron oxide, alkali, water and optional additives may be formed into a variety of shaped articles by compaction, moulding, extruding or slip forming.
- the method of formation will be largely determined by the composition of the mixture and the nature of the finished shaped article.
- a variety of shaped articles may be formed using this invention including tiles, pavers and construction materials such as bricks, blocks and the like.
- the shaped article may be allowed to cure in ambient air at a temperature of about 20-40 C. Under these conditions, curing will normally be completed in about 7 days.
- the energy requirements of the invention are quite low, thereby contributing to the relatively low cost of these shaped articles. It has, however, been found that it is possible to substantially accelerate the curing time by increasing the curing temperature, for example, by curing at 100°C in a confined environment.
