Procedure: Īdjust the cup of the liquid limit apparatus with the help of tool gauge and adjustment plate to give a drop of exactly 1cm on the point of contact on base. For determination purpose liquid limit may be defined as the water content at which a part of soil, cut by a groove of standard dimensions, will flow together for a distance of 1.25 cm under an impact of 25 blows in a standard liquid limit apparatus. LIQUID LIMIT (IS 2720 Part V - 1985) Aim: To determine the liquid limit of the given soil sample (-425 micron sieve) Equipment & Accessories: Casagrande Liquid limit device, grooving tool, porcelain dish, 425 micron sieve, spatula, balance (0.01 gm sensitivity), water content cans, oven, distilled water.įig.1 Casagrande apparatus Theory: Liquid limit is the water content at which the soil passes from zero strength to an infinitesimal strength hence the true value of liquid limit cannot be determined. 130 WORKABILITY OF CONCRETE BY SLUMP TEST.133 WORKABILITY OF CONCRETE BY VEE - BEE CONSISTOMETER METHOD.136 COMPRESSIVE STRENGTH OF CONCRETE.138 BULKING OF SAND.141 FLEXURE STRENGTH OF CONCRETE. 127 WORKABILITY OF CONCRETE BY COMPACTION FACTOR. 120 INITIAL SETTING AND FINAL SETTING TIME OF CEMENT.122 SOUNDNESS OF CEMENT. 106 DUCTILITY TEST.109 SOFTENING POINT TEST. 91ĪGGREGATE ABRASION TEST (Los Angeles Machine). 88 AGGREGATE ABRASION TEST (DEVAL MACHINE). 85 SPECIFIC GRAVITY AND WATER ABSORPTION. 33 MODIFIED PROCTOR COMPACTION TEST.37 CALIFORNIA BEARING RATIO TEST (HEAVY COMPACTION).40 CALIFORNIA BEARING RATIO TEST – LIGHT COMPACTION. 26 PERMEABILITY TEST – VARIABLE HEAD METHOD.
