(54) RAW MIXTURES FOR THE MANUFACTURE OF ARBOLIT

(57) The invention relates to the production of building materials for various purposes and can be used in the manufacture of leaf-etched mixtures, as well as in the production of related materials such as

As arbolit, fiberboard, etc., In order to reduce the cost and setting time, the raw mixture for the manufacture of arbolit contains the following components, in weight.h .: cement 800-850; lime 400-450; ash. 500-550, grass 300-350; foliage 50-60; needle needles 25-30; coniferous cones 25-30; water 1500-2000. Material density 300 - 700 kg / m, class B 0.35-2.35, heat transfer coefficient 0.07 -, 0.14, compressive strength

 In a day, 7-18 kgf / cm. 2 tab.

The invention relates to the production of building materials for personal use and can be used in the manufacturing of sheet metal-trapetized mixtures, as well as in the production of related materials such as fibrolite, xylolite, etc.

The purpose of the invention is to reduce the cost and setting time.

The manufacturing process for arbolite is as follows.

Grass, foliage, pine needles and cones are harvested, all this is dried in the sun or in equipped rooms until dry, then these raw materials are crushed by machines into fractions from 2 to 15 mm and sieved in sieves, depending on the purpose of the leaf etch. The pulverized mass crushed mass prepared from all fillings dp of the leaf etched mixture must be metered in a volumetric-weight metering device.

The sheet-etched mixture is prepared in forced cyclical mixers of the type SB-35 (C-773), SB-62 (C-951) or paddle mixers of the C-209, CM-290 type.

The following sequence of loading mixers is compounded by the components of the sheet-etched mixture at pre-soaking the filling. Teley - grass, foliage, coniferous needles, g cones, cement, lime, ash.

Water to the mixer is fed through a pipeline with an adjustable flow through the flow meter.

The duration of the mixing of the listotravolitic mixture, counting from the moment all materials are loaded into the cyclic mixer and until the beginning of its discharge,

with

onbiTiibiM by and must be at least 5 minutes.

The sheet-travolit mixture should be supplied to the place of laying should have the required density in the compacted state with about: deviation not more than j: 5%,: delamination rate not more than 10%, | cement separation rate: dough within 20-30 s, geperanth | RU within. j The listotravolitic mixture must (have a hardness with a three-fold: viscometer or mobility of at least 2 cm on the sediment of the cone;; loss of components (drinkers. Leaf-etched constructions And products are formed in steel with the help of two bunker concrete pavers of the type, etc.

Compaction of the levottravolit mixture to obtain a product of the required average density is a responsible technological operation. Leaf etching mixture is not amenable to the general laws of Hiernost, inherent in concrete mixtures with other types of aggregates. Ordinary vibration in this case is ineffective (due to low gravity and elastic properties. Pistotravolitic mixture); the fact that the elimination of the elastic mixture and the violation of the compacted structure are removed by the removal of the load; During the preparation of the mixture, the result of which the mixture is small is further with: high water consumption. Therefore, in practice, it is necessary to maintain high values of W / C equal to 10-11. The technology of listetravolite production is adopted by vibrating method with loading.

Example l-. In laboratory conditions, cubes of 15X15 15 cm in size are made from cement M-400, ground lime, ash, grass, leaf of you, conifer needles, conifer cones, crushed fraction of 2-15 mm and water.
