NEW INDUSTRIAL PROCESS FOR OBTAINING HIGH STRENGTH ARTIFICIAL AGGREGATES

NEUVO PROCESO INDUSTRIAL PARA OBTENER GRANULADOS ARTIFICIALES DE GRAN RESISTENCIA

The shell grip process enables aggregates with a high degree of micro-rugosity and a high degree of wear resistance to be produced. The bauxite which is sintered at 1600 deg C, gives a high wear resistance; the material contains a high proportion of aluminium and has few disadvantages; in the course of laying, it combines with a binder rich in resin. The types of bauxite which may be used and the principal deposits which exist in South America are described, as well as the phases in the sintering process. Amongst the conclusions which are outlined, the disadvantages are listed (the basic material is not readily available and the price is high) and the advantages such as the very high quality in comparison to natural aggregates, its anti-skid properties and its high degree of porosity which increases the adherance with the binders. /TRRL/
