جرمهای ماله کشی
جرم های نسوزی که در اجرای آنها از ماله برای پخش بتن روی سطوح به طور صاف استفاده می شود به جرم های نسوز ماله کشی نامیده می‌شوند. این روش برای سطوح کوچک صاف و مستقیم مناسب است.
ویژگیهای جرم های ماله کشی
به دلیل جلوگیری از تجمع ذرات سیمان در سطح و سفت شدن سطحی بتن ماله کشی نباید زیاد از حد باشد، چرا که با سخت شدن سطحی فرایند خشک شدن و خروج آب مشکل خواهد شد. برای ماله کشی توری سیمی نصب شده و جرم مخلوط شده با آب به داخل توری اعمال شده و در نهایت با ماله روی سطح صاف می شود. ضخامت لایه برای ماله کشی حدود 40-20 میلیمتر است.
کاربرد جرم های ماله کشی
جرم های ماله کشی به کمک دست قابل اجرا و نصب هستند و معمولا برای مکانهایی که قابلیت استفاده از دیگر تجهیزات وجود ندارد استفاده می‌شود.
