Makes 250 block per hour
No additeves need
No need for drying or curing
walls constructed with these blocks also offer excellent isolation
against the cold heat and noise. Most of the construction codes of
in the U.S.A. require a R=19 factor. The insulation factor of these
blocks is R=40 that is, much greater. They also offer great resistance
to sismic movements and depending of the constructions design, engineers
and architects are in agreement that the construction of walls constitutes
the most important factor for sismic resistance.

A METALIC MESH OF 1 INCH IS RECOMMENDED TO SIFT STONES AND OTHER MATERIALS THAT ARE NORMALLY MIXED WITH THE EARTH.
Estimated production costs for earth blocks with 300 ISOFORM Machine based ont the production of: 8 hours x 250 blocks per hour x 25 days month = 50.000 blocks
LABOR AND SUPPLIES
(Expressed in US Dollars)
Earth mix: 1 cubic meter = $ 3,00
1 cubic meter = 98 blocks of 30 xs 15 xs 10 cm.
50.000 Blocks = 510 cubic meters = $ 1,530.00
1 galon x 1 hr. x 8 hrs. x 25 days x $ 1.50 = $ 300.00
Hydrulic oil: = $ 10.00
Machine operator, montly salary = $ 400.00
Montly salary = $300.00 (8 hrs. Work day) x 4 = $ 1,200.00
TOTAL LABOR AND SUPPLIES
$ 3,440.00 divided by 50,000 = US$ 0.069 per block
Plus machine depreciation cost.
The machine depreciation cost can be calculated on the following basis:
Average machine price FOB Miami = $ 19,950.00
Freight and Insurance = $ 400.00 to $1,000
Import duties = ????
Example: to depreciate the total machine cost in Two years: Asuming a final machine cost at work site of $ 25,000.00 and working 5 years, 8 months of 25 days of 8 hours, it would produce 2'000,000 blocks. The cost per block atributable to the machine would be $ 0.0125 that added to the cost of labor and suplies results with a final cost of $ 0.0815 PER BLOCK.
