The Unconfined Compressive Strength Properties of the Compressed Stabilized Earth Block

This research is carried out mainly to study the geotechnical properties of the compressed earth block which is produce from Injana’s soil samples which were collected from three different locations near Kirkuk governorate. The local soils were blended to make a good soil mixture of gravel 0.09 percent, sand 82 percent and 17.43 percent of fine grain particles for manufacturing compressed earth blocks. The wet soil mixture compacted manually by manual press which is globally known as CINVA-RAM exerting high pressure estimated by 17.2 MPA to produce all soil blocks. Then the blocks were cured for 28 days and tested for unconfined compressive strength and moisture content. Based on the results, it was concluded that the compressive strength increases as the moisture content decrease, in the sense that it is increases as the age of blocks increases, where the highest compressive strength is recorded (55.5) MPA after 28 days of curing.
