Definitions

  • the fly ash and slag components are mixed, usually with a binder such as bentonite or sodium silicate which provides green strength, formed into shape and fired at elevated temperatures, generally in the region of 1100°C.
  • a binder such as bentonite or sodium silicate which provides green strength
  • the fly-ash or, in the case of Smith 4,120,735, the incinerator residue
  • the particle size distribution of the coarse component will also effect the properties and composition of the green and fired product. For example, where the coarse component is relatively deficient in smaller particles, a greater proportion of fine component will be required to achieve a given bulk density.
  • the alkali metal compound typically sodium silicate
  • the alkali metal compound will normally be added in aqueous solution, and the quantity of additional water, which may also be required to achieve correct plasticity, will be determined by experiment.
  • the total initial water content of the unfired mixture will depend on the process by which the article is to be formed, whether by extruding or pressing, for example.
  • the green product is, of course, dried before firing, to minimize the quantity of free water.
  • the blast furnace slag had a maximum particle size of 3 mm and the following approximate composition:
  • the sodium silicate solution was that with a silica-soda weight ratio of the order of 2.25 and a density of the order of 1.56 with a solid content of approximately 46%.
  • the proportion of fly-ash was determined by adding fly-ash to a sample of slag until maximum bulk density was achieved, so that the proportions employed represent the maximum packing of the two ingredients for the particle size range of the two components.
  • the ingredients were mixed for three minutes in a planetary mixer and tiles were formed on pallets in a conventional concrete tile making machine. The tiles were then dried for two hours at approximately 90°C. Immediately after the tiles left the drier, a low temperature acid resistant ceramic glaze was applied by spray applicator.
  • the glazed tiles were stripped from the pallets and fired over a period of three hours, the maximum temperature being approximately 820°C, and the tiles being gradually reduced from this temperature to a kiln exit temperature of approximately 130°C.
  • Pieces of sample tile were tested for water absorption by being stood on end in approximately 1 cm of water for 24 hours, then totally immersed in water for a further 24 hours, and then boiled in water for 45 minutes.
  • the following table shows the water absorption ( % ) measured after each of these treatments, respectively designated as A, B and C:
  • the quality of glaze on the fired tile was excellent, with a strong bond and very little gas bubble formation.
  • Sodium silicate solution 15 In order to examine the physical behaviour of the tile during a firing cycle, a bar of this material was taken through a cycle of heating to 1000°C in a dilatometer followed by cooling, and the same sample was subsequently subjected to a further heating and cooling cycle in the dilatometer.
  • Fig. 1 illustrates the dilatometer curve produced in the first "firing" of the sample, while Fig. 2 shows the curve obtained in the second cycle.
  • Figs. 1 and 2 the percent change in length is plotted against temperature in °C.
  • the dilatometer was operated on a normal cycle with a rate of temperature change of 3°C per minute, the sample being in an air atmosphere.
  • Fig. 1 The major effects revealed in Fig. 1 occur between 600°C and 850°C.
  • the bar Prior to 620°C, the bar expands linearly with rising temperature. In the region of 620-630°C softening of the material commences, and the dilatometer records a sharp contraction through the temperature zone of 700- 800°C where the material is in a pyroplastic state, while beyond approximately 850°C linear expansion is resumed, although the expansion of the sample recorded in this region is assumed to be in fact bloating, as the slag particles soften sufficiently to release entrapped gases.
  • the curve of Fig. 2 shows the material behaving quite linearly throughout the temperature range, with no contraction occurring in the region of 600-800°C.
  • the linear behaviour of the sample in Fig. 2 indicates that the reaction occurring in the unfired sample in the 600- 800°C region is not repeated, and was completed in the course of the first dilatometer cycle.
  • Fig. 3 shows the dilatometer curve of a tile sample previously fired over a 4-hour cycle to 860°C. In this curve the scale of the vertical axis is magnified for the purpose of clarity. The sample shows the characteristic form of Fig. 1, but the contraction which occurs in the pyroplastic zone is only of the order of 0.3%, compared with 2% in the unfired specimen of Fig. 1.
  • the coefficient of thermal' expansion revealed by the dilatometer curves is of the order of 10 x 10 , and is comparable with those of terracotta tiles or common bricks.
  • fly-ash and blast furnace slag are employed, it is believed that a reaction occurs at the surface of the fly-ash particles which essentially involves the dissolution of Al 2 0 3 to form a sodium aluminosilicate. At the interface with the slag particles, it is believed that a similar reaction takes place, accompanied by the formation of a lime soda alumina silica glass.
  • tile composition employing a substitute for the fly-ash as the fine component material was prepared from a mixture of slag, manganese mud and sodium silicate solution in the following proportions:
  • An attractive alternative to blast furnace slag for the purpose of the coarse component in products according to the present invention is fine-grained mafic rock such as basalt.
  • Such a material contains no significant quantities of free silica, and therefore does not exhibit a quartz inversion. It has a low coefficient of thermal expansion and is capable of short firing times.
  • Mafic rocks also contain no hydrated water, and the green product is therefore not subject to drying shrinkage, which cannot be tolerated in the production of tiles on pallets.
  • Basalt furthermore contains suitable quantities of metal oxides to enable a surface reaction with the sodium silicate.
  • Basalt-based tiles have been produced with strengths approximating those of the slag-based tiles (3000 Newtons) but with superior characteristics in greater acid insolubility, and in the shorter firing cycle which is possible due to the fact that the tiles can be raised to the maximum firing temperature and cooled from this temperature more quickly without the cracking which would occur when using blast furnace slag.
  • Example V
  • O PI raised to approximately 700°C, and the contraction of the material through the pyroplastic region is more gradual.
  • the slag will no doubt contribute silica to the reaction with the caustic soda, and fly-ash may also act as a source of silica.

Abstract

Une tuile ou autre élément de construction est fabriqué par cuisson d'un produit vert formé à partir d'un composant grossier tel qu'un laitier métallurgique ou de la roche concassée et un composant fin tel que des cendres volantes, avec du silicate de sodium ou autre composé de métal alcalin qui réagit avec au moins le composant fin pour former une matrice de liaison.
