Description
The CLU 3000 was developed in 1980 by the Consolid AG, Switzerland. It succeeded the CLU 2000 (developed in 1977), which was the first self-sufficient, self-powered mobile soil brick plant, fully equipped with a mechanically geared paddle mixer and hydraulically operated, valve controlled press and extruder.
The CLU 3000 incorporates a double mixer unit, the upper mixer used for blending the chemical compounds with the soil, the lower one completing the mixing process and simultaneously feeding the rotating moulds. The 4-station rotating table automatically turns 90° for each step (filling, inspecting, pressing and ejecting). The mixer can also be used independently, if only mortar needs to be mixed.
The whole plant is mounted on a special one-axle trailer with spring-suspended 7.00 x 14 tyres, an adjustable shaft bar, a height adjustable front wheel and hand break. Any suitable vehicle (from a tractor to a bullock cart) can be used to tow the plant to the next production site.
International Cooperation
Numerous building projects in Africa, Asia and Latin America have been carried out with soil bricks made with the CLU 3000 and incorporating the additives of the CONSOLID system.
The machine and the chemical products arc being manufactured under licence in Mexico and India, as well as in other countries in the near future.

The CONSOLID System
Three chemical products, designed to control the water sensitivity of soil as a construction material, were developed in the early 1970s by the CONSOLID AG, Switzerland:
CONSOLID 444 a liquid, used in proportions of less than one part per thousand parts of soil, serving to agglomerate the fine particles irreversibly, thus reducing the capillary rise of water and improving the compactability of the soil. CONSERVEX a liquid, used in proportions of less than 1 % by weight of the soil, to further reduce the tendency to absorb water, thus improving the effectivity of CONSOLID 444. SOLIDRY a dry powder, used instead of CONSERVEX, in the same proportions, in cases when the soil is too moist to permit the satisfactory blending of CONSERVEX. SOLIDRY can also be added to cement and lime to improve
Additional Equipment
CATAPULTER Sieve Machine - Model UNI 400 - which pulverizes soil lumps and removes coarse particles larger than 20 mm, in order to provide the uniform, finely grained soil required for high quality brick production.
The mobile sieve machine (equipped with two semi-pneumatic tyres) is powered either by 7 hp gasoline engine or 5.5 kW electric motor. Weight 220 kg; dimensions 725 x 700 x 1400 mm; output approx. 3 m³ soil per hour.
Operating the CLU 3000
Two workers are required to fill the mixer with loose soil (100 litres for each batch), additives, such as cement, lime and/or chemical waterproofing compounds (CONSOLID 444 and CONSERVEX), and water. After thorough blending, the mixture is discharged into the lower mixer by means of a sliding valve. Further mixing takes place, and when the rotating table is started, the material is continuously filled into each mould, as it passes under the hole at the bottom of the mixer. In this way, the moulds are always filled with the same quantity of soil mix, ensuring a uniform thickness of the bricks.
The next turn (90°, anticlockwise) exposes the filled mould for inspection by the third worker, who operates the control switches and thus can respond to any deficiencies immediately. Moving to the next position can be controlled manually or automatically at variable speeds, with intervals between each quarter-turn of about 6 to 10 seconds.
At the third station, each brick is hydraulically compacted by applying 15 tonnes (corresponding to 5 N/mm²). The finished brick is ejected at the fourth station, where a fourth worker removes the brick and places it for drying.
Special Rental Service
The CLU 3000 Soil Brick Plant with electric motor is also available on a rental basis within Europe. Special discounts are negotiable for rental periods exceeding 30 days.
The machine is available ex works and can be towed by any suitable vehicle or loaded on a truck. The transportation including a transportation insurance can be arranged by Intrex GmbH at cost price, if the customer so wishes.
A detailed manual for the production of compressed soil bricks and for the operation and maintenance of the machine is supplied with the CLU 3000.
