This soil was stabilized using 4% and 10% OPC for manufacture of blocks of size 19 cm × 9 cm × 9 cm. The blocks were admixed with 4%, 6%, and 8% SBA by weight of dry soil during casting, with plain OPC stabilized blocks acting as control. All blocks were cast to one target density and water content followed by moist curing for a period of 28 ...

The soil, raw or stabilized, for a compressed earth block (CEB) is slightly moistened, poured into a steel press (with or without stabiliser) and then compressed either with a manual or motorized press. CEB can be compressed in many different shapes and sizes. For example, the Auram press 3000 proposes 16 types of blocks. The input of soil ...

The use of earth as a building material, in different forms, such as unburnt and burnt bricks, rammed earth, mud blocks, and soil blocks, is a common practice globally. This study is focused on soil blocks stabilized with cement which are referred to as Cement Stabilized Earth Blocks (CSEBs). The strength and durability of CSEBs are primarily ...

Area Building Code Standards Vol. 7:1995 does not say much on these requirements. All it specifies is that adobe and stabilized soil blocks should be made of clay soil. And soil with high drying shrinkage (black cotton soil) should be avoided. Many countries also do not have standards for soil block building construction.

Suitable soil type should have a clay content of between 15% and 35%. High-clay soils will require the addition of sand and a higher cement content to prevent blocks from cracking. Low clay soil may not suficiently bind the block without additives. Each m3 of soil produces approximately 110 blocks. 20 m3 of soil are needed to produce 2,200 ISSB ...
