Предшестващо състояние на техникатаPrior art
Бетоновите смеси представляват микс плътна маса, която се получава от смесването в точно съотношение на основни компоненти като цимент, вода и натрошен камък в различни фракции. В зависимост от предназначението на бетоновите смеси са налице специални изисквания към всеки един от компонентите му - като количество, размер, форма, чистота, състав, свойства. За подобряване качествата на бетоновата смес и втвърдения бетон се използват пластификатори, противозамръзващи добавки и други химични добавки.Concrete mixes are a mix of dense mass, which is obtained by mixing in a precise ratio basic components such as cement, water and crushed stone in different fractions. Depending on the purpose of the concrete mixtures, there are special requirements for each of its components - such as quantity, size, shape, purity, composition, properties. To improve the qualities of the concrete mix and hardened concrete, plasticizers, antifreeze additives and other chemical additives are used.

Като инертни материали в състава се включват фин пясък 0/3 mm, едър пясък 0/5 mm и грахов чакъл 5/15 mm, а като добавки се използват суперпластификатор и в дадени случай ускорител.The task was solved by creating a composition of concrete, including cement, aggregates, water and additives. Fine sand 0/3 mm, coarse sand 0/5 mm and pea gravel 5/15 mm are included as inert materials in the composition, and superplasticizer and, in some cases, accelerator are used as additives.
Компонентите на състава на бетона са в следните тегловни проценти: цимент от 19 до 23%, вода от 6,9 до 7,8%, инертни материали от 70 до 73%, суперпластификатор от 0,15 до 0,19% и/или ускорител от 0,14 до 0,19%.The components of the concrete composition are in the following percentages by weight: cement from 19 to 23%, water from 6.9 to 7.8%, aggregates from 70 to 73%, superplasticizer from 0.15 to 0.19% and/or accelerator from 0.14 to 0.19%.
Инертните материали са разпределени в следните тегловни количества: фин пясък 0/3 mm 11,24%, едър пясък 0/5 mm 38,76% и грахов чакъл 5/15 mm 50%.Aggregates are distributed in the following weight amounts: fine sand 0/3 mm 11.24%, coarse sand 0/5 mm 38.76% and pea gravel 5/15 mm 50%.
В едно примерно изпълнение, компонентите на състава на бетона са в следните тегловни проценти: цимент 20,51%, вода 7,67%, инертни материали 71, 46%, суперпластификатор 0,18% и ускорител 0,18%.In one exemplary embodiment, the components of the concrete composition are in the following weight percentages: cement 20.51%, water 7.67%, aggregates 71.46%, superplasticizer 0.18%, and accelerator 0.18%.
Инертните материали са разпределени в следните тегловни количества: фин пясък 0/3 mm 11,24%, едър пясък 0/5 mm 38,76% и грахов чакъл 5/15 mm 50%.Aggregates are distributed in the following weight amounts: fine sand 0/3 mm 11.24%, coarse sand 0/5 mm 38.76% and pea gravel 5/15 mm 50%.
В друго примерно изпълнение компонентите на състава на бетон са в следните тегловни проценти: цимент 20,55%, вода 7,69%, инертни материали 71, 58% и суперпластификатор 0,18%.In another exemplary embodiment, the components of the concrete composition are in the following percentages by weight: cement 20.55%, water 7.69%, aggregates 71.58% and superplasticizer 0.18%.
Количествата на инертните материали в състава в тегловни проценти са следните: фин пясък 0/3 mm 11,24%, едър пясък 0/5 mm 38,76% и грахов чакъл 5/15 mm 50%.The quantities of aggregates in the composition in percentage by weight are as follows: fine sand 0/3 mm 11.24%, coarse sand 0/5 mm 38.76% and pea gravel 5/15 mm 50%.
Предимство на полезния модел е, че бетоновите състави са механически устойчиви и икономически изгодни, тъй като се намалява количеството на използвания цимент, като се запазват устойчивостта на натиск на бетона и неговата хидравлична свиваемост.An advantage of the utility model is that the concrete compositions are mechanically stable and economically advantageous, as the amount of cement used is reduced, while maintaining the compressive strength of the concrete and its hydraulic compressibility.

И в двете примерни изпълнения, инертните материали са разпределени в следните тегловни количества: фин пясък 0/3 mm 11,24%, едър пясък 0/5 mm 38,76%, грахов чакъл 5/15 mm 50%.In both exemplary embodiments, aggregates were distributed in the following weight amounts: fine sand 0/3 mm 11.24%, coarse sand 0/5 mm 38.76%, pea gravel 5/15 mm 50%.
Бетоновите състави се произвеждат в стационарна бетонова инсталация, която позволява автоматично дозиране на всички компоненти. Посредством транспортна лента към смесителя се подават инертните материали, които са предварително дозирани. Циментът се подава към смесителя чрез шнекове, след което се зарежда и необходимото количество вода. Следва разбъркване на сместа в продължение на около 2,5 min до нейното хомогенизиране.The concrete compositions are produced in a stationary concrete plant that allows automatic dosing of all components. By means of a conveyor belt, the inert materials, which are pre-dosed, are fed to the mixer. The cement is fed to the mixer through augers, after which the required amount of water is also charged. This is followed by stirring the mixture for about 2.5 min until it is homogenized.
