Samenstelling, eigenschappen en werkwijze voor het vervaardigen van een brandwerend konstruktieraateriaal.Composition, properties and method for manufacturing a fire-resistant construction material.

ie uitvinding heeft betrekking op mengsels van een hydraulisch bindmiddel en eventueel een epoxysysteem , gesinterde vliegaskorrels en vul- en toeslag- en hulpstoffen, alsmede op de eigenschappen van deze mengsels 5 na verharding, alsmede op de wijze waarop deze mengsels worden toegepast.The invention relates to mixtures of a hydraulic binder and optionally an epoxy system, sintered fly ash granules and fillers and additives and additives, as well as to the properties of these mixtures after curing, and to the manner in which these mixtures are used.

Het is bekend vliegas toe te passen als gedeeltelijke vervanging van cement in betonachtige konstrukties waaronder spuitbeton uit b.v, de werkzaamheden van de 10 0ÜR-V3 commissie B33. Verder worden gesinterde vliegaskorrels toegepast als gehele of gedeeltelijke vervanging van toeslagstoffen zoals grind in betonachtige konstrukties.It is known to use fly ash as a partial replacement of cement in concrete-like structures, including shotcrete from e.g. the work of the 10 0ÜR-V3 commission B33. Furthermore, sintered fly ash granules are used as a full or partial replacement for additives such as gravel in concrete-like structures.

Het is bekend dubbel-matrix-bindmiddelmengsels, 15 bestaande uit cement en een epoxysysteem toe te passen in betonachtigen uit b.v, de Nederlandse octrooiaanvragen 7905199 (Rütgerswerke) en, ook gecombineerd met gesinterde vliegaskorrels, 3501557 (Schoenmakers <& van Ooijen), alsmede in spuitbeton uit b.v. de Duitse octrooien 20 DE 3136737 en DE 30348517 (Oebr.Köhne).It is known to use double-matrix binder mixtures consisting of cement and an epoxy system in concrete-like materials from, for example, Dutch patent applications 7905199 (Rütgerswerke) and, also combined with sintered fly ash granules, 3501557 (Schoenmakers <& van Ooijen), as well as in shotcrete from e.g. German patents DE 3136737 and DE 30348517 (Oebr.Köhne).

Bovendien is bekend vliegas met thermoplastische kunststof als bindmiddel toe te passen in bouw- en isolatiemateriaal uit de Nederlandse octrooiaanvragen 3C02816 en 8002817 (Vojewodzkie Przedsiebiorstwo 25 V/odociagow i Kanalizacji, Polen).Moreover, it is known to use fly ash with thermoplastic plastic as a binder in construction and insulation material from the Dutch patent applications 3C02816 and 8002817 (Vojewodzkie Przedsiebiorstwo 25 V / odociagow i Kanalizacji, Poland).

Verder is bekend brandwerende bekledingslagen te vervaardigen met mengsels waarin b.v. Vermiculite en/of Perlite verwerkt wordt uit b.v. toepassingen in Nederlandse tunnels in de wegenbouw.It is further known to produce fire-resistant coating layers with mixtures in which e.g. Vermiculite and / or Perlite is processed from e.g. applications in Dutch tunnels in road construction.

30 Uitsluitende vervanging van een deel van het cementgehalte door vliegas heeft echter weinig effekt op de brandwerende eigenschappen van het materiaal in de konstruktie, evenals alleen toepassing van voornoemd dubbel-matrix-bindmiddel-mengsel.However, exclusive replacement of part of the cement content by fly ash has little effect on the fire-resistant properties of the material in the construction, as does only the use of the aforementioned double-matrix binder mixture.

Yoornoemde, uit Polen afkomstige materialen hebben als nadeel dat zij uitsluitend fabrieksmatig 5 onder hoge temperaturen van 160-200 graden Celsius en door middel van extrusie tot konstrukties kunnen leiden en toepassing in of op bestaande konstrukties daarmee, ook economisch bezien, onhaalbaar wordt.The disadvantages of said materials originating from Poland have the drawback that they can only lead to constructions under high temperatures of 160-200 degrees Celsius and by means of extrusion, and that application in or on existing constructions thus becomes economically unfeasible.

De voornoemde bekledingslagen bezitten nagenoeg 10 geen bruikbare konstruktieve sterkten, terwijl zij bovendien met relatief dure grondstoffen zijn samengesteld.The above-mentioned coating layers have practically no useful structural strengths, while they are moreover composed with relatively expensive raw materials.

Yan gehele of gedeeltelijke vervanging van toeslagstoffen door gesinterde vliegaskorrels, b.v. van het type Lytag, kan als groot nadeel genoemd worden dat de 15 korrel een redelijke hoeveelheid vocht absorbeert, hetgeen bij blootstelling aan temperaturen ver boven het kookpunt van dat vocht, tot sterke dampuittreding aanleiding zal geven.Complete or partial replacement of additives by sintered fly ash granules, e.g. of the Lytag type, it can be mentioned as a major drawback that the grain absorbs a reasonable amount of moisture, which will give rise to strong vapor exit when exposed to temperatures far above the boiling point of that moisture.

Het was derhalve een taak van de uitvinding een 20 samenstelling te ontwikkelen, die veilige optimale brandwerende eigenschappen bezit, die bovendien als konstruktie- en/of konstruktief' reparatie-materiaal over voldoende eigen sterkten beschikt, en die met bestaand materieel betrekkelijk eenvoudig en economisch op ver-25 schillende ondergronden en onder verschillende uitvoerings-omstandigheden toepasbaar is.It was therefore a task of the invention to develop a composition which has safe optimum fire-resistant properties, which moreover as construction and / or construction repair material has sufficient inherent strengths and which, with existing equipment, is relatively simple and economical to use. different surfaces and can be used under different operating conditions.

Dit doel wordt bereikt door een bindmiddelmengsel van cement, eventueel aangevuld met vliegas, en water eventueel met een epoxysysteem, toegevoegd aan gesinterde 30 vliegaskorrels, eventueel aangevuld met gebruikelijke vul- en toeslagstoffen, eventueel onder toevoeging van vezelvormige materialen, door middel van het zogenaamde droge of natte spuitbetonsysteem aan te brengen.This object is achieved by a cement binder mixture, optionally supplemented with fly ash, and water, optionally with an epoxy system, added to sintered fly ash granules, optionally supplemented with conventional fillers and additives, optionally with the addition of fibrous materials, by means of the so-called dry or apply wet shotcrete system.

Bij voorkeur bestaat het bindmiddel uit cement, 35 met een keuze uit de aangeboden soorten» Yraagt de toepassing om een bindmiddelmengsel met een epoxysysteem dan viorden de resultaten geoptimaliseerd door toepassing van hoogsulfaatbestendige cementsoorten. Als toeslagstoffen wordt een samenstelling van gesinterde vliegas- 8502007Preferably the binder consists of cement, with a choice of the types offered. If the application involves a binder mixture with an epoxy system, the results are optimized by using highly sulphate-resistant cements. A composition of sintered fly ash 8502007 is used as additives
