raw material proportion of producing the soil interlocking bricks

the soil interlocking brick machine mainly use the soil to produce the soil interlocking bricks.
cement,sand and other material also need to be added.
but what is the the raw material proportion is suitable?
below raw material proportion can be as reference:

using Fly ash – Lime – Gypsum – Cement- Sand (Fal-G), other fly Ash based combination OR Soil-Cement (Compressed Stabilized Earth Blocks SEB) OR Stone Dust – Cement.
Different mix designs can be made to suit the quality, cost of raw material and compresive strength of blocks required. Eg. the blocks have been successfully made using following combinations :
Fly ash = 35% – 60%
Coarse sand = 35% – 70%
Stabilizer = 8% – 15% (including lime, cement, gypsum)
Soil = 60 – 70%
Coarse sand = 20 – 30%
Cement = 5 – 10%
The block strength is determined by nature of Soil / Fly Ash , quantity of Cement and other materials used . The water curing after manufacture of blocks plays a important role in final compresive strength and quality of blocks.
In past we have obtained results as indicated below:
Soil – Cement Blocks Fal-G – C. Sand
Cement Content Strength Cement Content Strength
5% 4 to 5 MPa 8% 7 to 8 MPa
10% 7 to 8 MPa 10% 12 to 13 MPa
1 MPa is equal to 10 Kg / Sq. cm
It can be up to 3 times better than conventional brick masonry.
Good quality blocks can be made to give:
For Fly Ash- Cement: Up to 15%.
For Stabilized Earth Block: Up to 12%.

  1. موضوع جيد جدا
    و انا اسال عن المعالجه بعد التصنيع بالمياه كيف تكون المعالجه و كم من الوقت تستغرق فتره المعالجه هل يوم او يومين او اكثر
    ارجوا التوضيح

  2. you write soil
    put each plce have speical soil
    can you explain from where you take the soil from river ,field , garden . mount ,
    how we know if the soil in our country suitable with this kind of brike
    notic (we have not this kind of bricks)

  3. What is your country name?
    there are no special requirement in the soil.
    the soil from field and garden is good.
    the soil need to be powder and less sand in the soil.
    i will send you a file about how to chose the soil into your email box.

  4. Hi
    I bought an Interlocking Brick machine driven by an engine but I wanted to know if I need to sift the soil instead of using murram soil. Do I need to sift it so that we remove the big stones and use only very small stones? I am from Uganda and also is it true that we don’t use sand and instead use cement and soil?
    Thank you dear.
