PROCEDURE FOR THE PRODUCTION OF CONCRETE WITH MIXTURES OF AGGREGATES ABSORBENT WITH WATER-REJECTING MATERIALS TREATED ONE, AND DEVICE FOR THE EXECUTION OF THE PROCEDURE

The invention refers to a procedure for the production of concrete with mixing of with water-rejecting materials, like with organic Siliziumverbindungen, like Chlorsiloxanen and Methylsiloxanen, and/or organic metal complexes, like chrome, Aluminiumund Zirkonverblndungen, and/or oberflächenaffinen cation-active fatty acid derivatives or with one or with several of the following connections: Sodium - methyl - Siloxan potassium - methyl - Siloxan Phenyl - methyl - Siloxan treated, absorbent aggregates, whereby the aggregates with the water-rejecting lugs le are oberfläehenbehandelt, u.zw with a concentration, those the absorbency of the Zuschläge by the influence of the alkality of the water cement mixture time-dependently only at most up to for the solidification of the concrete mixture obstructs Nr.347842 after the patent and on a device for the execution of the procedure. In the patent Nr.347842 it is suggested that materials are zugeraischt, which obstruct the absorbency of the Zuschläge over a selectable time interval also after the production of the concrete mixture. Among other things it is suggested that the absorbent addition before bringing in with hydrophoben substances, which lend water-rejecting characteristics to the Zaschlagstoff” are treated. The dry and sucking aggregate, thus blowing clay/tone, hut pumice od.dgl, “hydrophobiert”, is called brought by treating with a chemical means, which has the characteristic to lend to the aggregate water-rejecting characteristics to take up no water. The dry and absorbent aggregate does not need to be protected after the production no more against rains or moistening, since it is made water-rejecting. The storage is open and without canopy possible. During the production of concrete the aggregate takes up water not unnecessarily and can without Vornässen for the production of concrete be used. With the suggested substances the hydrophobe 2s effect is time-dependently overcome by the alkality of the water cement mixture. Thus one has the certainty that a wetting of the addition is not prevented by the water cement mixture. The chemical means for the hydrophobic treatment of the dry absorbent addition is to lose the hydrophobe effect in the concrete mixture after penetration into a concrete mixture after an appropriate time, so that according to the concrete its Gesetamäßigkeit can tie and confirm. For impregnating the aggregate two possibilities present themselves, i.e. either a dipping or a spraying. The disadvantage of these procedures preserves however therein that the absorbent aggregate is inclined to suck itself when dipping with impregnating agent fully since the grain is extremely strongly sucking. As a result of it difficulties and a large consumption of impregnating agent arise. When spraying 2um part the same difficulty arises or however, if one is selected not to strong Besprü3S hung, the danger that the grain is not moistened “all around”. In order to avoid this difficulty, it is suggested that the aggregates are impregnated through capers, whereby on a temperature between 100 and 300°C, on 200°C aggregates heated up are preferably passed through if necessary between two caper media with soft-porous surface coatings, which are soaked with the impregnating agent. During painting the impregnation of the grain takes place by wetting of the surface by contact with a caper medium, in which the impregnation liquid is stored. With contact with the surface of the caper medium the Imprägnierflü s is sigkeit delivered. Such soft-porous surface coatings, for example foam rubber, foamed plastic od.dgl., store the impregnation liquid in the pores. This withdraws on pressure. Since the grain volume with the impression covers itself, necessarily arises to no more liquid than 4S. It is e.g. possible that at least one roller with soft-porous surface-laminated, which is soaked with impregnating agent, and a further soft-porous is intended surface-laminated, which is also soaked. The grain is put on a soft-porous surface-laminated. With the roller over the grains one drives, which press themselves into the Oberflächanschichten. Thus the impregnating agent is squeezed out. Each grain is coated with security at the surface again with in such a way the impregnation liquid. It, if two moving in opposite directions turning and affecting oh savings alleles rollers are intended, is particularly appropriate those the porous layers, which are soakable with impregnating agent, exhibits. The grains of the aggregate are accomplished between the rollers and impregnated by squeezing the impregnation liquid out and coated with the impregnation liquid superficially. Since the rollers touch themselves, inevitably a Rundumbenetzung arises. Further the rolling deer speed is to be variable. By the roller speed one can steer the duration of the contact with the wetting liquid and thus the impregnation depth. One is by painting able, only the impregnation a surface-laminated, u.zw. to reach in an exactly depth assignable depending upon roller speed. The caper temperature in particular the aggregate can lie between 100 and 300°C, preferably with 200°C. During the production of blowing clay/tone or hut pumice the aggregate comes hot, i.e. with some 100°C from the rotating furnace. Since one has it by the rollers in the hand to reach an only short surface contact and the cancellation with the hydrophoben substance the warmth stored in the grain is sufficient, which solvents are solved, in soft the hydrophoben substances, e.g. water, in addition, other solution liquids to bring to evaporating. This is for example the case if the moisture absorption is only about 5 to 1OB of the dead weight. Effected via it, dar3 the Potymerisation and achievement of the hydrophoben surface let themselves reach extremely rapidly. The grain has practically after the cancellation, however with security after short time a hydrophobe surface. By controlling of the rotating speed and/or the Finführungstemperatur one can reach empirically the optimum for a certain impregnation liquid and/or a certain addition. The invention is described on the basis of in the designs represented remark examples more near, without itself on it to fuel element” chr'änken. Fig. 1 points a simple caper device, Fig.2 in side view and partial section in side view and partial section a further remark example and Fig.3 to it an opinion from above. In the remark example in accordance with Fig. 1 is a tub --4-- planned, those with a foam rubber plate --fi-- is filled, which is soaked with an impregnating agent. Furthermore is a slidegate valve --2-- with a roller --1-- planned, whereby the roller with a foam rubber-laminated --3-- is covered, which is soaked with the impregnating agent also. The grains of the aggregate, in the remark example blowing clay/tone, --6-- on the foam rubber plate are up-strewn. By driving the roller --1-- over the grains these become into the foam rubber layers --3 and 5-- imprinted and, since they thereby lmprägniermittel from the Moosguramischichte squeeze out, with impregnating agent are coated. In the remark example in accordance with the Fig.2 and 3 are two itself moving in opposite directions turning rollers --7 and 8--, whose is adjustable speed, with foam rubber layers --9 and 10-- occupied, those in tubs --13, 14-- dip, those with impregnation liquid --21-- are filled. Squeezing roles--11 and 12--it ensures for the fact that the Moosgummisehichten --9 and 10-- are always evenly soaked with impregnating agent. The rollers --7 and 8-- are around the axles --15, 16-- swivelling. A conveyor --17-- serves for supplying from blowing clay/tone to a distributor chute --18--, those the blowing clay/tone evenly between the rollers --7, 8-- leads. A conveyor --19-- serves for would drive off the coated and impregnated blowing clay/tone. Coming from the kiln, the blowing clay/tone becomes with a temperature of for instance 200°C --20-- the distributor chute --18-- supplied and slips between the foam rubber layers --9 and 10-- the rollers --7 and 8--, those with impregnation liquid --21-- are soaked. When going through the rollers Imprägnierflüssigkei¢ becomes from the foam rubber layers --9 and 10-- squeezed out and each blowing clay/tone grain with security with impregnating agent coated. So that too much impregnation liquid is not taken up, is the roller speed of the rollers --F and 8-- accordingly selected. The blowing clay/tone grains fall on the conveyor --19-- and the Lösllngsmittel evaporates owing to their self-warmth, in which the water-rejecting substance is solved. At the grain verb] eibt, as desired, a water-rejecting layer. The remark examples show only some possibilities of the invention, without being limited to it. So for example volumes, bind-like mats can be used od.dgl, instead of rollers. Instead of foam rubber another suitable Trägersehichte for the impregnating agent can be used. Instead of blowing clay/tone another material, e.g. od.dgl., can find hut pumice use. S0
