What are the compressed earth blocks (CEB)?

Compressed earth blocks (CEBs) are a strong, low-value way of building a residence, office environment, or neighborhood. CEBs can be employed to make walls, flooring or even a roof. The blocks are environmentally helpful, extensive long lasting, and able to endure the harshest climate conditions. They also have a lessen embodied electrical power than traditional concrete and brick.

Compressed earth blocks (CEBs) are a inexperienced, environmentally welcoming design material that can be developed with neighborhood resources and provide a tough, sustainable, and economical developing resolution. CEBs are made from soil, aggregate, and water which is compressed to develop blocks. These blocks can be employed as a substitute for conventional supplies such as cement, wooden, brick or block.

What is the very best soil for CEB?

The soil contains the 75% sandy soil, and 25% clay soil is best. You can incorporate 4% to 8% Portland cement to ensure the toughness of the compressed block.

The finest ratio of CEB is: 92-96% soil and 4-8% cement.

If the soil has significant clay, you have to have to increase the extra sandy soil.

If the soil has superior sandy soil, you need to insert some clay.

The excellent soil: sand:80%. Silt: 10%, clay: 10%

The great soil: sand:65-80%. Silt:-20%, clay: 10-20%

The Soil Information:

  Sand Silt Clay
Ideal Soil 80% 10% 10%
Excellent Soil 65-80% -20% 10-20%


How to establish if your soil is sandy soil?

Sandy soil refers to soil that includes sand gravel. Sandy soil consists of fine particles of limestone, granite, and quartz shaped by erosion, weathering, and fragmentation.

You need to have to complete a straightforward squeeze exam. You get a handful of soil that is not pretty moist, and then squeeze it into a ball to see if the soil can totally kind a block or a ball. Sandy soil will not clump, and if sand If the content is way too substantial, the soil will operate away from you.


Most soils have a few components, namely sand, silt, and clay. Sand has the most significant soil particle sizing, silt has a soil particle dimension amongst clay and sand, and clay has the smallest particle sizing.

Sand refers to grains with a particle dimensions of .074~2mm that are washed by rain or rolled from the rock soon after weathering.

The type of soil can also be distinguished. The soil with more than 85% of the sizing of sand is called sandy soil.


What are the advantages of compressed earth block?

Heat in winter season and great in summer months

CEB is a great thermal insulator, which can shop warmth in cold winters to guarantee that the temperature of the space will not quickly eliminate.

In the warm summer time, it can also be stored neat properly and will not enable the warmth from exterior the area arrive in.

Small design expense

The uncooked materials soil can be taken domestically. There is a great deal of soil close to you, only a small total of cement is wanted, and the charge is tremendously reduced in contrast with concrete bricks. And it also reduces the transportation cost of raw products.

Pollution-cost-free, healthy

Earth is the oldest building substance. People initially employed soil to make houses.

The raw materials are all normal and will not launch preservatives and toxic gases.

Environmental defense, sustainability

The production process of compressed soil bricks does not want to eat a good deal of warmth, simply because the bricks you deliver do not need to be fired, and you can specifically dry and remedy them by natural means.

When the house wants to be rebuilt in the foreseeable future, these developing products can nevertheless be recycled.

How to make compressed earth blocks?

The compressed earth block equipment manufactured by Lontto is specifically used to develop CEB. According to the variation of automation, it can be divided into handbook earth block machine, semi-computerized CEB machine, and entirely automated CEB machine.

First, combine the soil in a certain proportion, 95% soil, 5% cement or lime, include an appropriate quantity of h2o, blend in a mixer, and then transportation the raw components to the brick device via a belt conveyor, which is hydraulically driven to push and variety.

The ceb device can generate a variety of various dimensions of bricks, just will need to alter unique molds.
