Experimental results of a uniaxial compression test for a saturated soft rock with low permeability verified an initial increase of rigidity and a strength reduction.

Through the unconfined compression test and triaxial rigidity test without drain, the authors studied the properties and influence of different formula for the clay-cement grout.

Thin PP spun-bond nonwovens can be tested and estimated by the traditional method and instruments for fabrics, the properties of compression, rigidity, compliance and crease recovery etc.
