Chalk Crushing Value

Document Status. Current Supplement. Civil & Structural Supplement. Series. BS. Abstract. Describes methods of test for determining characteristics related to the compaction of soils, which can be used as a basis for specifying requirements for soils compacted in the field.

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

shear stress is the shear strength of the soil for the particular value of the normal force N or normal stress (N/A) applied to the soil, where A is the cross sectional area of the soil sample. Fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.

Various points of concern were noted by Greenwood, 1989 (ref 2) in the application of the LR806 chart and the use of the Chalk Crushing Value (CCV) test:- The CCV test procedure was cumbersome, the chalk grade was not particularly dependent on the CCV, and the use of saturation moisture content alone did not reflect the degree of saturation.
