Weight concrete - Learn all about this feature !

volume and specific weight of the concrete - than to use when assessing the material?

operate everywhere in the construction value of the weight of the material.Where most often you will need knowledge of its value: in calculating the purchase and delivery of the required number of components, determining the possible load on the building envelope construction formwork, the estimated density and heat loss resulting monolith, etc.How to be?

In this case, a reinforced bulk density, a parameter determined by calculating its weight by a certain amount.And here come into force characteristics of fillers, pore formation, the degree of filling of the bubble volume, etc.As is known, high-quality cubic meter of concrete can weigh more than two and a half tons.These compositions are particularly strong, made with crushed stone and special fillers, used for bookmarks responsible bases, caps, etc.

At the same time, light compounds having more than eighty percent of its bubble volume filling structure can have less weight than five hundred cubic meter kilograms.These special light materials more suitable for the performance of the heat-insulating structures.

Weight concrete products - which fillers affect this value?

examined early extreme variants weight materials, it should be noted that conventional formulations for lightweight fillers are different perlite, expanded clay and natural sand.This ingredient is a mandatory participant in all kinds of solutions.For lightweight materials it takes up to six kilograms.

possible implementation of porous structures without the use of expanded fillers, such as foam concrete or aerated concrete, with a smaller percentage of bubble content than the compositions particularly light.In general, this group of weight concrete products range from a hundred to one tonne of eight kilograms per cubic meter.It is in this group of materials are manufactured finished lightweight building blocks.

Aggregates in the form of crushed stone or gravel are used for heavy trains.The weight of 1 m3 of concrete with such fillings range from one ton of eight kilograms to two and a half tons.The basic part consists of ballasts (1.3 m), sand (0.75 m), cement (0.45 m) and water to two hundred liters.

way, with the complexity of determining the specific weight of the material, it is easy to find on the densities of ingredients constituents.Adding these parts by weight, without the weight of evaporated water, get two and a half tons per cu.The use of such compounds, is considered a classic, extremely broad and varied.

Talking about the compositions of strength, it should be noted that the weight of the concrete cube is not directly determines the performance.Rather, the greater the effect of the used cement brand, while dependent on the filler weight of a cubic meter of the obtained material (the strength influenced by its density).

The compositions especially heavy concrete is often scrap metal are included, barytes, magnetite and hematite.The weight of one cubic meter of these compounds is from two to three and a half tons.These materials are used on the most critical areas of armored covers and other protective facilities, well prevent the spread of radiation.

weight concrete - what else changes, this figure?

important factor affecting the final strength of the materials is correct calculation solutions.According to the density of the solutions experts say hard, plastic and alloy compositions.Their payment is determined by the properties necessary for the works of the final material depends primarily begins with the proportions of water and cement.

volumes of water to concrete mass has the desired strength can not be taken less relevant, but the excess can lead to the formation of voids and pores, adversely affecting this important characteristic.

Another, no less important step that affects the amount of water is the future factionalism fillers, their size and the ratio of cement.In per 1 m3 of concrete, the weight can be determined approximately on the components, as discussed above.However, you need to take into account and the characteristics of the water used.But efficiency and density (and hence largely strength) of the resulting material, mainly will depend on the proportion of large and small fillers in the mixture.

As a rule, the volume of water adjusted and are expressed as a share of the cement.It is necessary to take into account the fact that the practical density rarely corresponds to the absolute value of the presence of a certain amount of residual water in the pores of the material and its evaporation in recruiting them strength (which lasts up to a month).
