The use of polystyrene concrete in construction hasa number of advantages associated with certain characteristics of the substance. After all, this is a universal material, which is most often used for work related to insulation, it is durable, has low thermal conductivity, and also good resistance to extreme temperatures, due to which it is not amenable to the action of fire. And due to the low weight of polystyrene concrete, made by hand, it is convenient to use, the shrinkage of the building is minimal. The composition of the same material, as a rule, includes water, filler and astringent.
What is necessary for manufacturing
When polystyrene concrete is produced byhands, you can use in addition to the above components and quartz sand, foamed polystyrene in granules. Depending on what kind of density should be in the end concrete, you should carefully choose the size and dosage of all components. So, for the manufacture of polystyrene concrete D550 sand and cement are mixed in one-to-one ratio, after which foamed polystyrene is added to this mixture, usually put 0.5 cubic meters. After all the ingredients have been mixed, the resulting mass is placed in a concrete mixer and turned on at medium power. During work, add water, tar, constantly mixing the whole mixture.
When polystyrene concrete is ready for work
To prepare polystyrene concrete with your own hands,Tar is used because it gives the mixture water-repellent properties. After the mixing process has been completed, the resulting mixture is poured into molds that can be easily made from boards, knocking them together and treating the inside with engine oil. The setting time of the mixture is, as a rule, about 24-25 hours, after which the block is pulled out of the mold and left in a cool place to dry. After two or three weeks they will be ready for use.
