Qumtosh eng ko'p ishlatiladigan toshlardan biri bo'lib, ko'plab geologik ketma-ketlikda keng tarqalgan va arxitektura maqsadlarida osongina qo'llaniladi. Qurilishda qumtoshning boshqa toshlarga nisbatan asosiy afzalligi shundaki, uni oddiy qo'l asboblari - yordamida cho'kma tekisligi bo'ylab osongina ajratish mumkin va tabiiy bo'linish yuzlari juda zarur.
Qumtoshlar o'z tarkibidagi donalarning tabiatiga ko'ra turlicha bo'lib, hajmi, tarkibi, shakli, pürüzlülüğü va erish darajasi bilan farq qilishi mumkin.
Zarrachalar turli bantlarda joylashgan bo'lishi mumkin va tabiiy tsementning sifati va turi o'zgaruvchan. Bularning barchasi har qanday qumtoshning o'lchamli tosh sifatida o'zini qanday tutishiga ta'sir qiladi.
Qumtosh har doim ham eng ko'p qirrali tabiiy tosh emas, asosan asl qoplama jarayoni tomonidan qo'yilgan cheklovlar tufayli. Qumtosh dengiz konlaridan kelgan joylarda to'shaklar nisbatan yupqa bo'ladi va bu stacklar zaif tomonlarni yaratishi mumkin, garchi ular toshni yulka va polga bo'lishda, ba'zan esa tom yopish uchun ishlatilishi mumkin.
Qumtosh an'anaviy blokli toshli toshlardan foydalanishda ohaktoshga nisbatan afzalliklarga ega bo'lishi mumkin, chunki hatto pastroq sifatli qumtosh ham ohaktosh zarar etkazadigan darajada ishlatilmaydi (garchi o'tmishda ohaktoshga etkazilgan zararning katta qismi kislotali yomg'ir bilan bog'liq bo'lishi mumkin, ammo unchalik emas). endi keng tarqalgan).
Ehtimol, ohaktosh va qumtosh o'rtasidagi asosiy farq qumtoshda mikroporlar tarmog'ining yo'qligi bo'lib, ular ohaktosh kabi uzoq vaqt davomida suvni ushlab turmaydi va shuning uchun sovuqning ta'siridan kamroq ta'sirlanadi.
Bundan tashqari, qumtoshlar kamroq umumiy g'ovaklikka ega. Bu tosh kamroq suvni ushlab turishi mumkinligini anglatadi va suvning muzlashi yoki tuzning kristallanishi va yorilish yoki boshqa shikastlanishlar tufayli ichki bosimning oshishi ehtimoli kamroq.
The main disadvantage that sandstone exhibits compared to most other stones is the presence of different types of substrates that can affect various properties. For example, small amounts of carbonate in the matrix can significantly reduce resistance to acidic influences. Many sandstones contain small amounts of clay minerals, which are generally inert but sometimes swell, causing damage under constant cycles of wetting and drying. In some cases, clay-rich inclusions or regions will weather rapidly.
Unlike many building stones available, it's hard to imagine an environment where sandstone would appear out of place. This may be because sandstone makes up most of our own landscape.
Through a brief exploration of new developments in sandstone design and preparation, as well as the material's inherent environmentally friendly properties, it is clear that sandstone is rapidly becoming the building material of the future. Combined with the timeless advantages of sandstone, including its durability, strength and slip resistance, as well as increasing value over time, sandstone has proven itself to be a versatile and useful stone.
