| titleOfInvention | Improvements in or relating to processes for the production of a mass of hardening structural material for the manufacture of tubes, plates or the like |
| abstract | Hardening shaped members are produced by adding dry cement to a suspension of one part of short-fibred chrysotile asbestos having a maximum fibre length of 0.5 mm. in at least 20 parts of water and added material, the proportion of the short-fibred asbestos being between 1.5 and 6.0 per cent by weight of the remaining dry ingredients. Long-fibred asbestos, mineral wool, slag wool, glass wool and cellulose may be added separately or in admixture. The suspension may be obtained by grinding chrysotile asbestos with 20-50 parts of water in ball mills or hollanders until a slimy mass is obtained, alternatively a heater may be used. The asbestos in the suspension preferably amounts to 2 to 6 per cent by weight of the dry mixture. In examples 90 Kgs. of cement are mixed with either 8 Kgs. long fibred, or medium fibred asbestos or slag wool, and 2 grams of finely ground asbestos added in 50 or 55 litres. In a further example 48.5 Kgs. of cement and 48.5 Kgs. of sand are mixed with 70 litres of suspension containing 1.5 Kgs. of very finely ground asbestos.) |
