  1. 01

    «O'lik» sement nayrangi

    Sement do'konlari muddati o'tgan sementni qanday qilib yangidek sotishadi.

    The trick

    Qotib qolgan (tosh bo'lib qolgan) sementni maydalab, yangi qoplarga qayta qadoqlash.

    The fix

    Qopni qo'l bilan ushlab ko'ring: burchaklari yumshoq bo'lishi kerak. Qattiq bo'lakcha sezilsa — olmang.

  2. 02

    Beton markasini suv bilan «o'ldirish»

    Nega ustalar betonga ko'p suv qo'shishni yaxshi ko'rishadi?

    The trick

    Beton suyuq bo'lsa uni yoyish oson — ish kamayadi. Lekin bu betonning markasini (mustahkamligini) 2–3 barobar tushirib yuboradi.

    The fix

    Konus sinovini talab qiling. Suyuqlikni suv bilan emas, plastifikator (kimyoviy dobavka) bilan oshirish kerak.

  3. 03

    «Shishirilgan» smeta: yashirin ko'paytirish

    Prorablar material miqdorini qanday oshirib ko'rsatishadi?

    The trick

    Masalan, 100 metr armatura ketsa, smetaga 120 metr yoziladi — 20 metri «zapas» va o'g'irlik uchun.

    The fix

    Har bir bo'limni geometrik hisob bilan alohida tekshiring: uzunlik × soni. Botdagi kalkulyator shuni qiladi.

  4. 04

    Armatura: «diametr o'yini»

    12 lik armatura aslida 12 likmi?

    The trick

    Sotuvchilar 11,2 mm armaturani «12 lik» deb sotishadi. Katta obyektda bu tonnalab pulni o'g'irlash degani.

    The fix

    Shtangensirkul bilan o'lchang yoki bir metrning og'irligini tarozida tekshirib, jadval bilan solishtiring.

  5. 05

    Shag'al va qum: «havo sotish»

    Samosval haydovchilari 10 kub yukni qanday qilib 12 kub deb sotishadi?

    The trick

    Mashina bortining pastiga yog'och qo'yish yoki yukni «do'mbaytirib» ortish orqali soxta hajm yaratiladi.

    The fix

    Bortni o'lchang: uzunlik × eni × balandlik = real kub. To'lashdan oldin shuni bir marta hisoblang.
