Cement is recommended for red sandy loams, low clayey soils.
If clay content is very low, the lime remains free. If clay content is high than lime cement combination may be used or sand may be added to the soil to reduce the clay content. Mud mortar is used in CEB masonry against cement sand mortar in conventional masonry. All these buildings are standing testimony to the strength and virtuosity of the technology.
