The hollow blocks are intended for use in reinforced masonry for low cost earthquake resistant housing.
The block dimensions have been especially conceived for modular coordination on the basis of 50 or centimeters: So CEBs would not be the best choice. It would appear that with proper care and maintenance, the life span of CETA-RAM, expressed in terms of production, could conservatively be estimated atblocks.
Quick calculation for a small house measuring 6m square by 2.
The block is then hand carried between the two pallets and carefully laid on its side on the ground, thereby freeing the pallets for immediate reuse.
This comes out to be convenient in the planning and execution of low cost housing projects, as it allows a modular coordination on the basis of 50 and centimeters, in both architectural and structural aspects. I wonder how these types of block would work as a retaining wall against a hill? The CETA-RAM is a manually operated block press, developed by the author just after the February Prdss Earthquake, specifically for the production of hollow soil-cement building blocks.

In properly constructed masonry walls, the holes are aligned through the full height blocl the wall, so that steel reinforcing rods can be inserted at suitable intervals and cement mortar grout poured in from the top, to achieve earthquake resistance.

A special vlock with dividing plate for making two half-blocks at a time has also been developed, as well as Inserts for semi-hollow froggedchanneled and rabbeted blocks. Not deducting for doors or windows for simplicity. Built entirely of steel, it is composed of three main assemblies see drawings: Size of machine length x width x height 40 x 25 x 70 cm 16 x 10 x 28 in.

The length of three blocks, included the respective joints, add exactly one meter. Before filling in the soil a steel pallet is laid at the bottom of the mould and after the compacted block is ejected, a second pallet is placed on top of it.

Any ideas or is this just too much for this type of material? Learn how your comment data is processed. I am really happy to have found this press nlock in Guatemala, I am looking bloci a CEB press for a crta project in El Salvador and this is my perfect match. Nevertheless, it is capable of molding at high pressure, dense and neatly finished blocks ofhigh structural quality, at the rate of to units per eight hour shift,when operated by two persons.

That means you could build a larger house for yourself, several smaller buildings around your homestead and then sell it to a housing group that could go on to make another 70 houses or so for poor people.
Twenty four blocks lay up one square meter of wall. Some of these machines have produced more than 60, blocks apiece, blick operational problems and without undue wear. Labour force required incl. Can you give me any contact? I really like the free plans. A Cinva ram seems best for typical heavy soils unless you have lightweight additives. This site uses Akismet to reduce spam.
My ebook explains how to build earthbag retaining walls that would be much stronger and more durable.
An alternative model of the machine has also been developed to produce both hollow and solid blocks. To date, CETA has presx more than 50 units, used in various rural habitational projects throughout the country and abroad.
Soil block presses: CETA- Ram
Thus the inserts can be removed to make solid blocks. I want to purchase 1pc of ceta ram were can I get it. My ears perked up when I heard lighter, faster, easier. These columns also serve as inserts to form the holes in the blocks. Do you know if it is still being built and sold?
