BS 5131: Section 2.7: 1980 (1992) - The preparation of test pieces from soling materials for physical . Abstract. Shrinkage limit, one of the Atterberg limits, is widely linked with many plasticity-based soil behaviors. However, in a great majority of these cases, such correlations have been found to exhibit poor performance. Recently, it has been brought out that the shrinkage limit of a natural soil does not depend upon plasticity characteristics, and it is . The water content corresponding to that stage is called as the shrinkage limit. i.e. Shrinkage Limit = [Weight of water at the stage when sample ceases to shrink] / [Dry weight of sample.] = [Total wt. of water – Loss of weight of water when sample ceases to shrink dry] / [Weight of sample] = {(W-W2) – (V1-V2)rw} / (Ws) x100 Also Read: Plastic Limit and Liquid . Step-2: Preparation of the specimen: The general procedures for preparing and marking out of samples are given in the British Standard. For critical work the recommended sample size is 500mm X 500mm and for routine work a minimum sample size of 300mm X 300mm is considered sufficient.The samples are marked with three sets of marks in each .
