What are the technical characteristics of construction plaster?Almost all plaster mixtures have similar properties. These include: 1. Density. The building material is a fine-grained structure. The average density varies from 2.6 to 2.8 g per CM. 2. Drying period. It adjusts in a few minutes. Experience shows that in the fourth minute after mixing it, the solution is set, and after 30 minutes it completely hardens. Therefore, the plaster must be diluted in small portions, otherwise it will harden and nothing can be done with it. However, there is a way to slow down this process. Glue for water-soluble animals is added to the solution. Its use does not affect the quality of the plaster in any way.

Qurilish gipsining texnik xususiyatlari qanday? Deyarli barcha gips aralashmalari o'xshash xususiyatlarga ega. Bularga quyidagilar kiradi: 1. Zichlik. Qurilish materiali nozik taneli tuzilishdir. O'rtacha zichlik sm ga 2,6 dan 2,8 g gacha o'zgarib turadi. 2. Quritish davri. U bir necha daqiqada sozlanadi. Tajriba shuni ko'rsatadiki, uni aralashtirgandan keyin to'rtinchi daqiqada eritma o'rnatiladi va 30 daqiqadan so'ng u butunlay qattiqlashadi. Shuning uchun gipsni kichik qismlarda suyultirish kerak, aks holda u qattiqlashadi va u bilan hech narsa qilish mumkin emas. Biroq, bu jarayonni sekinlashtirishning bir usuli bor. Eritmaga suvda eriydigan hayvonlar uchun elim qo'shiladi. Uning ishlatilishi gips sifatiga hech qanday ta'sir qilmaydi.
