Abstract

This is an addn. to 74.43348, which describes the use of scrap rock- or glass- wool. The scrap is mixed with sand, cement and water to form a material which can be cast in a mould, esp. to form building elements. The pref. mixt. contains equal amts. of sand and cement, each of which being equal to one-quarter of the amt. of scrap. The mixt. pref. also contains 1-3 wt.% w.r.t. the wt. of cement, of a setting accelerator. An example is a mouldable mixt. contg. 320 kg scrap rock wool; 80 kg sand, size 0/3; 80 kg cement; 1 kg accelerator; and 5-10 litres water. Vibration may be used to aid casting of the mixt.

Description

Le brevet principal concerne un procédé qui, destiné à la récupération des déchets de laine de roche et de laine de verre, consiste à mal-axer ces déchets avec du ciment let et avec de l'eau pour donner lieu à la formation d'un produit pâteux que l'on coule dans un moule et que l'on soumet à des opérations successives ou simultanées de vibration et de compression, avant de le sécher à l'étuve.  The main patent relates to a process which, intended for the recovery of waste rock wool and glass wool, consists in mis-focusing this waste with let cement and with water to give rise to the formation of a pasty product which is poured into a mold and which is subjected to successive or simultaneous operations of vibration and compression, before drying in the oven.

Les applications des déchets de laine de roche et de laine de verre ainsi récupérés sont nombreuses; et c'est ainsi que le brevet principal cite la- fabrication d'eléments de construction, tels que : agglomérés, panneaux, plaques
La présente addition vise à préciser un procédé de fabrication de telsélenentsl en vue de l'obtention d'éléments alliant d'excellentes propriétés mécaniques à leurs qualités isolantes provenant de la présence des déchets de laine de roche ou de laine de verre.The applications of rock wool and glass wool waste thus recovered are numerous; and this is how the main patent cites the- manufacture of construction elements, such as: agglomerates, panels, plates
The purpose of this addition is to specify a process for the manufacture of such elements in order to obtain elements which combine excellent mechanical properties with their insulating qualities originating from the presence of rock wool or glass wool waste.

Selon ce procédé, les déchets de laine de roche ou de laine de verre sont associés à du sable pour constituer un ensemble d'agrégats avec lesquels le ciment est mélangé et brassé en milieu aqueux. According to this process, the rock wool or glass wool waste is combined with sand to form a set of aggregates with which the cement is mixed and stirred in an aqueous medium.

Les proportions de déchets de laine de roche ou de laine de verre, de sable et de ciment ne sont pas impératives. Des produits présentant d'excellentes propriétés mécaniques et un bon pouvoir isolant sont cependant obtenus en adoptant la composition ci-après
- déchets de laine de roche 400 litres, soit 320 kg
- sable 0/3 ................................ 80 kg
- ciment ................................... 80 kg
- adjuvant accélérateur de prise de ciment.. 1 kg 6
- eau ........................... entre et 10 litres
Les déchets de laine de roche et le sable constituent les agrégats dont la teneur en humidité détermine la quantité d'eau à utiliser.The proportions of waste rock wool or glass wool, sand and cement are not imperative. Products having excellent mechanical properties and good insulating power are however obtained by adopting the composition below
- rock wool waste 400 liters, i.e. 320 kg
- sand 0/3 ................................ 80 kg
- cement ................................... 80 kg
- cement setting accelerator admixture. 1 kg 6
- water ........................... between and 10 liters
Rock wool waste and sand constitute the aggregates whose moisture content determines the amount of water to be used.

Après avoir été mélangé et brassé à froid dans un malaxeur, l'ensemble forme un mélange pâteux homogène qui est coulé dans des moules déterminant ia forme des éléments à obtenir. Dans leurs moules ces éléments sont ensuite soumis à des opérations de vibration et de compression qui peuvent être successives ou simultanées; et ils sont finalement séchés en étuve.  After having been mixed and cold stirred in a kneader, the whole forms a homogeneous pasty mixture which is poured into molds determining the shape of the elements to be obtained. In their molds these elements are then subjected to vibration and compression operations which can be successive or simultaneous; and they are finally dried in an oven.
