CONSTRUCTION MATERIAL AND PROCESS FOR MANUFACTURING SAME.
ll'o Drawing.
To all whom it may concern:
Be it known that we, PAOLO MARPILLnno, LORENZO LORENZETTI, and Ivo MAnzoLA, citizens of the Kingdom of Italy, residing at Milan, Italy, have invented certain new and useful Improvements in Construction Materials and Processes for Manufacturing Same, of which the following is a specification.
The present invention relates to construction materials consisting essentially of a combination of fibrous substances with a suitable cement, the said fibrous substances being composed of filaments or fibres of any kind which are sufliciently rigid and resisting.
The construction materials thus obtained are very light, porous and consistent. It is to be noted that the fibres do not serve as a filling material, but they constitute a reticulated fibrous structure in which the cement only serves to give the desired rigidity at the points where the individual fibres connect or contact with one another. The strength of the material, therefore, is not due to the binding cement but to the reticulated fibrous strpgture. As the mixture is formed W1 on any compression for the urpose of making it compact, the resultmg materials ought to be to a large extent spongy and so constituted that the fibres form as it were small bridges; this effect can be obtained when the mixture or paste is carefully made.
The process of manufacture of the materials forming the subject of the present invention consists in first of all subjecting the fibrous substances such as yaw, bggasse o1 sugg lfloane fibre, or Indiawnfibre, w qp d nas r tair jrlne press ni iille.
likeito a cdr nbing operation and then to an operation which makes them non-combustible, this latter operation consisting in treating them with an approximately 10% solution of mgggesiumsaltsmsodilm ate.
Immedia ely afterwards the fibrous mass is formed into a aste with powdered ide of magnesium, w ich may bemixed or not with Portland cgment plamor other suit- 1;
able equivalent substances.
The resulting moist mixture is not coherent and must be placed in moulds in which it is allowed to set for approximately a Application filed March 24, 1924. Serial No. 701,574.
fortnight. It may, however, be taken from the mould after two or three hours, when it has attained the desired consistency and be allowed to continue to set in the open air. a
The proportions of the fibrous part of the mixture and the agglomerating substance may vary according to whether it is desired to obtain materials which are .merely insulating or materials which offer a high re sistance to compression. These proportions may vary from .07 to 3 parts by weight of agglomerating substance to one part of fibrous material.
It will be clear that the proportions mentioned are given by way of example and that in practice they may be varied at will to suit the particular requirements of the case. The specific weight of the resulting materials is kept as a general rule below 800 kg. per cubic millimeter.
Having now particularly described and ascertained the nature of our said invention, and in what manner the same is to be performed, we declare that what we claim is:
1. A process of manufacturing light, insulating and porous construction elements, comprising the steps of subjecting a fibrous vegetable substance to the action of a fireproofing solution; intimately mixing the fibrous substance so treated, while still damp, with magnesium oxide and cementitious material to form a damp non-coherent mass; filling moulds with the damp mass and then allowing said mass to set at least partially and in an uncompressed state in the moulds.
2. A light, insulating and porous moulded construction element, comprising a mass of previously fire-proofed vegetable fibres intimately mixed with magnesium oxide and cementitious material and then allowed to set at least partially in an uncompressed state in a mould, thereby forming a reticulated fibrous structure which is rendered rigid by the cementitious material at the points where the individual fibres contact with one another.
In testimony whereof we aflix our signatures.
