How To Calculate Concrete Method B.O.W

Koef B.O.W based materials:

Cement = 0.76
Sand = 0675
Gravel = 0.52

This means that in 1 m3 of gravel consists of pebbles m3 + 00:52 12:48 airspaces

Semen Bj = 1250 Kg
1 zak = 50 kg

concrete mixer concrete method to calculate BOW
=====> 1 m3 of concrete 1: 2: 3 so the mixture = 1 * 0.76 = .76 m3
2 m3 sand mortar finished --------> = 2 * 0675 = 1.35 m3
3 m3 kerikir -------> so mortar = 3 * 12:52 = 1.56 m3
==========================================
Material ---- produces 6 m3 = 3.67 m3 concrete

1 m3 of concrete = 1: 2: 3 ===> needed materials ...
-------------------------
Cement = 1.3.67 * 1 m3 = 0.2725 m3 = 340.5995 kg = 6812 zak
Sand = 1.3.67 * 2 m3 = 0.5449 m3
Gravel = 1.3.67 * 3 m3 = 0.8174 m3


=====> 1 m3 of concrete 1: 3: 5 to be slurry = 1 * 0.76 = .76 m3
3 m3 sand --------> so mortar = 3 * 0675 = 2025 m3
5 m3 kerikir -------> so mortar = 5 * 0:52 = 2.6 m3
========================================
9 m3 of material ---- produces concrete = 5385 m3

1 m3 of concrete = 1: 3: 5 ===> needed materials ...
-------------------------
Cement = 1/5.385 * 1 m3 = 0.1857 m3 = 232.1263 kg = 4.6425 zak
Sand = 1/5.385 * 3 m3 = 0.5571 m3
Gravel = 1/5.385 * 5 m3 = 0.9285 m3


=====> 1 m3 mortar plaster / mortar 1: 5 to be slurry = 1 * 0.76 = .76 m3
5 m3 sand mortar finished --------> = 5 * 0675 = 3375 m3
================================================
6 m3 of material - resulting slurry mortar = 0.76 + 3,375 = 4,135 m3

1 m3 of slurry mortar = 1: 5 ===> needed materials ...
------------------------
Cement = 1/4.135 * 1 m3 = 0.2418 m3 = 302.2975 kg = 6.0459 zak
Sand = 1/4.135 * 5 m3 = 1.2092 m3
