Abstract

Blends of fly ash and polypropylene in ratios of 10-90 to 92-8 are used to make construction blocks suitable for paving, drains, roofing or moulded constructional fittings. The mixts. can be derived from cheap, industrial waste to form easy flowing moulding materials at 160-200 degrees C to make slabs etc. which are hydrophobic, strong, wear-resistant, resistant to acidic or basic chemicals and with good thermal insulation and dielectric characteristics.

Description

L'invention a pour objet un nouveau matériau de construction thermoplastique établi sur la base i cendres volantes, constituant un déchet lors de la combustion de charbon broyé et déposé sur les dépoussiéreurs électrostatiques. The subject of the invention is a new thermoplastic construction material established on the basis of fly ash, constituting waste during the combustion of ground coal and deposited on the electrostatic precipitators.

S'accumulant par les modes d'exploitation actuels dans les centrales thermiques et autres usines similaires, les cendres volantes constituent de grandes ressources de matière brute pour la production de matériaux,notamment de matériaux de construction. Accumulating by current operating methods in thermal power stations and other similar factories, fly ash constitute large raw material resources for the production of materials, especially construction materials.

On connait déà par les brevets polonais PL 70 394, PL 86 373 et PL 100 688 l'application de cendres volantes à la construction. On-les utilise comme addition pouzzolanique au ciment portland lors de la préparation de liants pour mortiers et bétons. On connaît de même la mise à profit de cendres volantes pour la production d'agrégats légers (Orientation et possibilité d'applica- tion de cendres volantes en Polognen - Institut dit Instytut Techniki BudowlaneJ, Warszawa 1977, pages 55 à 73).We already know from Polish patents PL 70 394, PL 86 373 and PL 100 688 the application of fly ash to construction. They are used as a pozzolanic addition to Portland cement when preparing binders for mortars and concretes. Likewise, the use of fly ash is known for the production of light aggregates (Orientation and possibility of application of fly ash in Polognen - Institute known as Instytut Techniki BudowlaneJ, Warszawa 1977, pages 55 to 73).

Les cendres volantes sont granulées auparavant par frittage. Fly ash is previously granulated by sintering.

Le granulé est broyé punis criblé en fractions appropriées. The granulate is ground punished and sifted into appropriate fractions.

Le nouveau matériau de construction thermoplastique est consitué de cendres volantes et de polypropylène, constituant un liant, assemblés entre eux par mélange à une température de 160 à 2000C. Le taux de cendres volantes peut varier de 10 à 92% et celui du polypropylène de 8 à 90% en poids. The new thermoplastic building material consists of fly ash and polypropylene, constituting a binder, assembled together by mixing at a temperature of 160 to 2000C. The rate of fly ash can vary from 10 to 92% and that of polypropylene from 8 to 90% by weight.

Le matériau de castruction selon l'invention présente une structure interne compacte, par suite de quoi il est hydrophobe. Il se caractérise par de bonnes propriétés diélectriques, une résistance mécanique importante, une faible usure et un bon écoulement lors du moulage. De même, il présente une grande résistance à l'ac tion chimique des composés acides et alcalins.  The castruction material according to the invention has a compact internal structure, as a result of which it is hydrophobic. It is characterized by good dielectric properties, high mechanical resistance, low wear and good flow during molding. Likewise, it has great resistance to the chemical action of acid and alkaline compounds.

I1 trouve son application comme lambris ou revêtement de sol, comme tqyau de canalisation, comme profilé de toiture et accessoire de construction. It finds its application as paneling or floor covering, as pipe pipe, as roof profile and construction accessory.

La mise à profit des matières premières entrant dans la composition de ce matériau de construction selon l'invention donne la possibilité d'appliquer les déchets industriels, donc elle s'avère utile à la protection du milieu naturel de lshomme.  The use of the raw materials used in the composition of this building material according to the invention gives the possibility of applying industrial waste, therefore it proves useful for the protection of the natural environment of man.

Le nouveau matériau de construction selon l'invention est décrit d'une manière plus détaillée dans les exemples de réalisation
Exemple 1
Cendres volantes 10% en poids
Polypropylène 90% en poids
On assemble les composants en les mélangeant à une température de 160 à 2000C et l'on moule par extrusion selon des iodes connus en soi, appliqués à la production de matériaux theroplastiques. The new building material according to the invention is described in more detail in the exemplary embodiments
Example 1
Fly ash 10% by weight
Polypropylene 90% by weight
The components are assembled by mixing them at a temperature of 160 to 2000C and are molded by extrusion according to iodines known per se, applied to the production of theroplastic materials.

Exemple 2. Example 2.

Cendres volantes 92% en poids
Polypropylène 8%
Les composants sont mélangé à une température de 160 200 OC puis la pâte est moulée par extrustion.Fly ash 92% by weight
Polypropylene 8%
The components are mixed at a temperature of 160,200 OC and then the dough is molded by extrusion.

Bien entendu l'invention n'est nullement limitée aux modes de réalisation. décrits et représentés qui n'ont été donnés qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits, ansi que leurs combinaisons si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre de la protection comte revendiquée.  Of course, the invention is in no way limited to the embodiments. described and represented which have been given only by way of example. In particular, it includes all the means constituting technical equivalents of the means described, as well as their combinations if these are executed according to the spirit and implemented in the context of the count protection claimed.
