بهتر است برای محاسبه مقدار شن و ماسه در بتن با معادل ابعاد کارگاهی آن هم آشنا باشیم. در همین راستا نیز اگر یک بیل حدود ۳ کیلوگرم سیمان بگیرد، برای یک مترمکعب بتن به ۱۰۰ بیل سیمان نیاز داریم. از طرف دیگر، هر فرغون ۱۸ بیل سیمان در خود جا میدهد، و هر بتونیر نیز ۳.۵ تا ۴ فرغون یا به عبارتی ۷۰ کیلوگرم سیمان. جابهجایی ۱ مترمکعب خاک را میتوان با ۷ فرغو...
