In properly constructed masonry walls, the holes are aligned through the full height of 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. Notify me of new posts by email.

I really like the free plans. The block dimensions have pfess especially conceived for modular coordination on the basis of 50 or centimeters: An alternative model of the machine has also been developed to produce both hollow and solid blocks.

A Cinva ram seems best for typical heavy soils unless you have lightweight additives. My ears perked up when I heard lighter, faster, easier.

The CETA-RAM is a manually operated block press, developed by the author just after the February Guatemalan Earthquake, specifically for the production of hollow soil-cement building blocks. I am really happy to have found this press produced in Guatemala, I am looking for a CEB press for a social 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.


So CEBs would not be the best choice. The hollow blocks are intended for use in reinforced masonry for low cost earthquake resistant housing. Thus the inserts can be removed to make solid blocks. Not deducting for doors or windows for simplicity.

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.

Two 6cm diameter holes run through its full thickness. The length of three blocks, included the respective joints, add exactly one meter. 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. Do you know if it is still being built and sold? The dimensions of the block are I wonder how these types of block would work as a retaining wall against a hill? 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. 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.

I just popped out my tape measure in curiosity. Built entirely of steel, it is composed of three main assemblies see drawings: Notify me of follow-up comments by email.

The holes simplify the placement of vertical reinforcement in earthquake resistant wall constructions: Your email address will not be published. Size of machine length x width x height 40 x 25 x 70 cm 16 x 10 x 28 in.


A special insert 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. Can you give me any contact? This press makes larger blocks than the Cinva ram to make better use of lightweight volcanic soil.

Any ideas or is this just too much for this type of material? Bock a little bigger and more efficient.

CETA Ram Block Press

To date, CETA has built more than 50 units, used in various rural habitational projects throughout the country and abroad. My ebook explains how to build earthbag retaining walls that would be much stronger and more durable. Some of these machines have produced more than 60, blocks apiece, without operational problems and without undue wear.

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.

Are they still building this way decades later?
