Energy Intensiveness of the Manufacture of Selected Products
Completion of definitions and new calculations of units with some items | Contents |
Bricks:
Brick unit: a brick of size 25 x 12 x 6,5 cm
1000 c.j. = 1,95 m3
Normal-sized brick = a brick of size 29 x 14 x 6,5 cm (= 1,3 c.j.)
1000 pcs. of normal-sized bricks = 2,639 m3
White brick = a brick of size 24 x 12,5 x 6,5 cm (1 c.j.)
1000 pcs. white bricks = 1,95 m3
Perforated bricks:
Perforated bricks of size 36,5 x 24,5 x 14,5 cm (=6,65 c.j.)
1000 pcs. perforated bricks = 12,966 m3
Perforated bricks II. of size 49 x 24,5 x 14 cm (= 8, 62 c.j.)
1000 pcs. perforated brick II. = 16, 807 m3
Cinder concrete bricks:
Cinder concrete bricks of size 38 x 25 x 22 cm (10,72 c.j.)
1000 pcs. cinder concrete bricks = 20,9 m3
Cinder concrete bricks II. of size 38 x 30 x 20 cm (= 11,7 c.j.)
1000 pcs. cinder concrete bricks II. = 22,8 m3
Burnt roofing:
HOLLAND TYPE:
Maximal surface mass = 45 kg/m2
Number of pcs/m2 = 14,4 pcs.
Unit mass = 1,8 kg/pcs.
BOBROVKA TYPE
Maximal surface mass = 70 kg/m2
Number of pieces/m2 = 1,8 kg/pcs.
Average specific mass is equal to approximately 1300 kg/m3
Fabrics:
Fabrics of all kinds are manufactured in widths from 0,6 m up to 1,6 m.
The most manufactured sizes are 0,9 m, 1,2 m and 1,3 m.
Conversion of usual metres on m2: m2 = bm x width (in meters)
The similar goes for new calculations of flat drawn glass of known thickness from square meters to cubic ones and similarly.
