Abstract
Invenția se refera la o compoziție lianta, pentru materiale de construcții, constituita din 75% zgura de fumai, 20% alabastru si 5% var sau calcar, componentele fiind granulate până la o dimensiune a granulelor de 0,063 nun.The invention relates to a composition binding, for building materials, constituted from 75% slag, 20% alabaster and 5% lime or limestone, the components being granulated up to one granule size of 0.063 nun.
Description
Invenția se refera la o compoziție lianți, pentru materialele de construcții.The invention relates to a binder composition for building materials.
Se cunosc compoziții liante, pe bază de zgură de furnal, ghips și alte adaosuri, cu caracter liant.Binder compositions are known, based on blast furnace slag, gypsum and other additives, with a binder character.
Compoziția conform invenției este constituita din 75% zgură de fumai, 20% alabastru și 5% var. Zgura de furnal este rezultata din procesul de elaborare a fantei.The composition according to the invention consists of 75% slag, 20% alabaster and 5% lime. The furnace slag is the result of the slit making process.
Alabastrul granulat rezulta ca produs secundar, la obținerea diferitelor sorturi de alabastru micronizat. Compoziția liantă se obține printr-o tehnologie simpli, utilizînd materii prime accesibile, cu un consum redus de energie, prezentînd un grad de alb ridicat. Compoziția lianți înlocuiește, în mortarele pentru betoane, cimentul Portland în proporție de 70...100%, conferind mărcilor de betoane respective, caracteristici fizico-chimice superioare.The granulated alabaster results as a by-product, when obtaining the different kinds of micronized alabaster. The binder composition is obtained by a simple technology, using accessible raw materials, with a low energy consumption, presenting a high degree of white. The binder composition replaces, in concrete mortars, the Portland cement in a proportion of 70 ... 100%, conferring to the respective concrete brands, superior physical-chemical characteristics.
Se dă, în continuare, un exemplu de realizare a compoziției liante conform invenției.The following is an example of making the binder composition according to the invention.
Se introduce într-un uscător rotativ uzual, ~un amestec alcătuit din -75% zgură de fumai, granulată sau expandată și 20% alabastru de Gălășeni, granulat.It is introduced in a regular rotary dryer, ~ a mixture made of -75% slag, granulated or expanded and 20% alabaster from Gălășeni, granulated.
Umiditatea amestecului, la ieșirea din uscător, este sub 5%. După uscare, amestecul obținut este depozitat intr-un depozit Intermediar, pentru a fî dirijat la fazele de micronizare, clasare pneumatică și ambalare - depozitare - expediere. Prin operația de clasare pneumatică, . sc separa granulele din amestec, cu o granulație < 0,063 mm, care sînt utilizate în compoziția liantă.The humidity of the mixture, when leaving the dryer, is below 5%. After drying, the obtained mixture is stored in an Intermediate warehouse, to be directed to the micronization, pneumatic sorting and packing - storage - shipping phases. By the pneumatic grading operation,. sc separates the granules from the mixture, with a granulation <0.063 mm, which are used in the binder composition.
Granulele, avînd o dimensiune >0,063 mm, se introduc din nou, la faza de micronizare, care se efectuează întro moară Humboldt uzuală. în faza de micronizare, se adaugă 5% var sau calcar granulat.The granules, having a dimension> 0.063 mm, are introduced again at the micronization phase, which is carried out in the usual Humboldt mill. In the micronization phase, 5% lime or granulated limestone is added.
Liantul obținut se livrează în vrac, în vagoane cisternă sau ambalat în saci de hîrtie sau polietilenă. Finețea liantului realizat este sub 0,063 mm, iar umiditatea sub 2%.The binder obtained is delivered in bulk, in tank cars or packed in paper or polyethylene bags. The binder fineness is below 0.063 mm and the humidity below 2%.
