The strength of mine backfill is fittingly represented by its compressive strength, which in the unconfined state is defined as the limit of the backfill material's resistance to compressive load (Fall et al., 2007). Usually, the strength of the cured backfill is very low compared to the strength of surround rock mass. (Zambia). A Thesis

Unconfined Compression Test (UCT) is a simple laboratory testing method to assess the mechanical properties of rocks and fine-grained soils. It provides a measures of the undrained strength and the stress-strain characteristics of the rock or soil. The unconfined compression test is often included in the laboratory testing program of

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength

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

Unconfined compression test of GMZ-1 on the compressive strength as a function of dry density (1.4, 1.6, 1.8 g/cm{sup 3}) and water content at room temperature was reported. With the same water content, a larger initial dry density leads to a larger unconfined compressive strength and a larger elastic modulus. Unconfined strength for GMZ-1 with
