Cementas yra hidraulinė rišamoji medžiaga dažniausiai naudojama statybinių medžiagų bei liejinių gamyboje. Cementas - pilkšvai žali milteliai. Jo sudėtis išreiškiama jame esančių oksidų procentais, kurių svarbiausieji yra CaO (62-64 %,), S1O2 (20-24 %), AI2O3 (4,0-7,5 %) ir Fe2Ū3 (2,0-5,0 %). Cementas gaunamas smulkiai susmulkinus klinkerį su tam tikru kiekiu gipso. Klinkeris gaminamas išdegus iki sukepimo molingus kalkakmenius arba kalkakmenio ir molio mišinius taip, kad išdegtame produkte vyrautų kalcio silikatai.Cement is a hydraulic binder commonly used in the production of building materials and castings. Cement is a greyish-green powder. Its composition is expressed as a percentage of the oxides it contains, the most important being CaO (62-64%,), S1O2 (20-24%), Al2O3 (4.0-7.5%) and Fe2Ū3 (2.0-5.0%). ). Cement is obtained by finely grinding clinker with a certain amount of gypsum. Clinker is produced by calcination of calcareous limestones or mixtures of limestone and clay so that calcined silicates predominate in the calcined product.
Polistirenas - tai amorfinis termoplastikas. Jis gaunamas polimerizuojant stireną ( C6H5 - CH = CH2). Ši medžiada yra kieta ir standi, tačiau trapi ir neatspari smūgiams. Polistireno trapumas ir neatsparumas smūgiams kompozicijoje nėra svarbi savybė. JiPolystyrene is an amorphous thermoplastic. It is obtained by polymerization of styrene (C6H5 - CH = CH2). This material is hard and rigid, but fragile and impact resistant. The brittleness and impact resistance of polystyrene in the composition is not an important property. She

Užpildas smėlis - tai birių gamtinių uolienų, kurių grūdelių matmenys iki 4 mm mišinys.Aggregate sand is a mixture of loose natural rock with grain sizes up to 4 mm.
Užpildas granito dulkės - tai atliekos 0,05-0,2 mm, gaunamos apdirbant granitą.Aggregate Granite dust is a waste of 0.05-0.2 mm obtained from granite processing.
Užpildas skalda - tai statybinė medžiaga iš susmulkintos natūralios uolienos ar dirbtinio akmens. Natūralių tankiųjų uolienų - akmens, granito , žvirgždo skalda plačiai naudojama betonų užpildams. Akmuo - tai kieta uoliena arba atskiras jos gabalas. Granitas - tai uoliena sudaryta iš kvarco kristalėlių, lauko špato ir žėručio. Žvirgždas - plačiai naudojamas statybos pramonėje betonų užpildams. Žvirgždas sudarytas iš gamtinių uolienų grūdelių, kurių matmenys 4-32 mm.Aggregate is a building material made of crushed natural rock or artificial stone. Natural dense rock - stone, granite, pebble chippings are widely used for concrete aggregates. Stone is hard rock or a single piece of rock. Granite is a rock made of quartz crystals, feldspar and mica. Pebbles - widely used in the construction industry for concrete fillers. The shingle consists of natural rock grains with dimensions of 4-32 mm.
Betono mišinio papildai yra cheminės medžiagos, pagamintos sintetinių tensidų ir/ar polikarboksilatų pagrindu. Papildai - tai modifikuoti priedai skirti nekeičiant konsistencijos pagerinti statybinių medžiagų ir betono liejinių kokybę. Dedami į kompoziciją nedideliais kiekiais maišymo metu. Superplastifikuojantis didelio efektyvumo vandens kiekį mažinantis betono mišinio papildas, pavyzdžiui „Sikament 56“ gerina statybinių medžiagų ir betono masės apdorojimą bei didina jos stiprumą ir mažina vandens įgeriamumą. Akytojo betono papildas, pavyzdžiui „Sika Aer-S“ sukuria didelį smulkių porų kiekį (išputina), tuo padidindamas jo atsparumą šalčiui kietame būvyje, sudaro lengvesnį tūrio masės vienetą, didina šiluminę varžą ir garso izoliaciją, suteikia geresnes apdorojimui savybes, pavyzdžiui, mažinant vandens atsiskyrimą ir separaciją.Concrete mix additives are chemicals based on synthetic tensides and / or polycarboxylates. Additives are modified additives designed to improve the quality of building materials and concrete castings without changing their consistency. They are added to the composition in small amounts during mixing. Superplasticizing high performance water-reducing concrete admixture, such as Sikament 56, improves the strength, strength and water absorption of building materials and concrete. A porous concrete supplement such as Sika Aer-S creates a large amount of fine pores (foam), thereby increasing its frost resistance in solid state, lighter weight per unit volume, higher thermal resistance and sound insulation, and better processing properties such as water separation and separation.
Statybiniai klijai - lipni medžiaga skirta kam nors sujungti, surišti.Building glue - adhesive for bonding and bonding something.
Statybiniai pigmentai - dažomoji medžiaga, suteikianti spalvą.Building pigments are colorants that give color.
Vandens kiekis priklauso nuo dedamo į kompoziciją mišinio kiekio ir turi būti parinktas taip, kad mišinys gerai išsimaišytų.The amount of water depends on the amount of mixture added to the composition and must be selected so that the mixture is well mixed.
Išradimas iliustruojamas pavyzdžiais, kur į kompozicijas buvo dedamas polistireno minimalus, vidutiniškas ir maksimalus kiekiai.The invention is illustrated by the examples where minimum, medium and maximum amounts of polystyrene were added to the compositions.
