It was found that micro-enterprise production of soil-cement can offer cost savings over sandcrete walling. The cost advantage is small 0 to 30 for built-up walling using current soil-cement block production systems. Soil-cement blocks are usually smaller than sandcrete blocks and consequently are more costly to lay because of the
