Flowable fill is defined by the American Concrete Institute47 as a self-compacting cementitious material that is in a flowable state at placement and has a compressive strength of 8.3 MPa (1200 psi) or less at 28 days. Most current applications for flowable fill involve unconfined compressive strengths of 2.1 MPa (300 psi) or less, which makes possible its excavation at a later date.

The tensile strength of compacts [30] also provides useful information. Excellent specimens of square compacts are necessary to conduct the tensile testing. For this reason, a split die [31 ] (Fig. 2) is used to make compacts that are not flawed. The split die permits triaxial decompression, which relieves the stresses in the compact more uniformly in three dimensions and minimizes cracking. These specimens are then compressed with platens 0.4 times the width of the square compacts in the tensile testing apparatus. (Fig. 3). Occasionally nylon platens and side supports are used to reduce the tendency to fail in shear rather than tension. The force necessary to cause tensile failure (tensile forces are a maximum... 

If, as stated above, Pcr lOkbar, then the question arises how stresses of this magnitude can be generated by impact in explosive compacts whose compressive strengths are about 100 fold less than Pcr. For unconfmed explosive compacts (in Kholevo No 2) this can only occur with thin explosive compacts, ie with explosive layers whose h/EKrelation between, Ou> the ultimate compressive strength of the explosive compact the average stress, Fu, at which the compact fails via brittle fracture (in compression) is ... 

The compressive strength of concrete is linked directly with the level of compaction. Therefore, concrete with zero slump should be compacted in different ways from conventional methods in which a vibrating table is used. These types of concretes are known as roller-compacted concrete (RCC) and usually contain low proportions of cement. 

Sampling of the stabilised soil was performed in order to evaluate the moisture, level of compaction and compressive strength of the blended soil and binder. The results (see Tables 42 and 43) were compared with laboratory results for quality control purposes. 

Semi-dry roller compacted paste using the novel binder with 13% water achieved the highest compressive strength of around 31MPa at 28 days age. 

Due to the slow strength development of the binder, roller compacted concrete (RCC) seemed to be the perfect way to lay the road base layer with acceptable compressive strength of 10-12 MPa at age of 28 days.
