Interlocking Stabilized Soil Blocks, or ISSB for short, are a type of building brick made from a mixture of soil, sand and cement compressed by hydraulic pressure. The bricks are designed to interlock and fit together, and during construction, because of their interlocking structure, a large amount of cement is not required, and the building wall can also have good stability.
Green and environmentally friendly
The raw materials used in interlocking stabilized soil blocks are mainly clay, which comes from local resources and is very easy to obtain, with low raw material costs. When producing interlocking stabilized soil blocks, the clay raw materials only need to be compressed and formed by a brick making machine, without the need for firing, which simplifies the production steps and saves energy and materials.
Low production costs
The invention of interlocking stabilized soil blocks reduces the production costs of manufacturers. Compared with expensive concrete brick building materials, interlocking stabilized soil blocks are more economical and efficient. It also reduces resource costs for society and provides employment opportunities for the local community.
Interlocking Stabilized Soil Blocks Raw Materials
01.Soil
Soil is the main raw material for interlocking stabilized soil blocks. We usually choose clay or sandy soil for fusion, which can achieve good compression performance.
02.Sand
The function of sand is to enhance the stability of interlocking stabilized soil blocks, but the proportion of sand to the raw materials should be moderate. Too much sand will cause the interlocking stabilized soil blocks to become loose, while too little sand will affect the strength of the interlocking soil blocks.
03.Cement
The proportion of cement generally accounts for about 5%-10% of the raw materials. As a stabilizer, cement can enhance the firmness and durability of interlocking stabilized soil blocks.
04.Water
Water can make soil, sand and cement fully blend together. The water content of the raw materials needs to be 10%. Too much or too little water will affect the formation of interlocking stabilized soil blocks.
05.Additive
In order to make the interlocking stabilized soil blocks stronger and more durable, some countries and regions add plasticizers, fly ash and other materials to the clay raw materials.
Production process of interlocking stabilized soil blocks
01.Prepare raw materials
First, choose the most suitable soil, which needs to contain a small amount of sand. Then screen the soil to remove impurities such as small stones and tree roots. Add sand, cement and water to the screened soil and mix them together. You can use a mixer to mix and blend, or you can do it manually.
02.Producing interlocking stabilized soil blocks
Pour the prepared soil raw materials into the mold of the M7M1 interlocking soil block brick making machine, apply compression force to the raw materials in the mold through the operating handle, and then compress them into shape, thus completing the production of an interlocking stabilized soil blocks.
03.Air drying and curing
Move the interlocking stabilized soil blocks that have been formed and demoulded to a cool place to air dry. The drying time varies depending on the weather and the size and thickness of the interlocking stabilized soil blocks. Finally, place the completely dried interlocking soil blocks neatly for storage and use.
