Sand replacement method is also known as sand cone method the apparatus used in this field density test consists of a sand pouring cylinder with pouring cone at its base there is a shutter between the cylinder and the cone

Sand cone density is an accurate and reliable test method that has long been used to measure the inplace density of soils the procedure is described in astm d1556 aashto t 191 a flat base plate with a 65in 1651mm circular opening is used as a template to position the hole at the test site

Nov 18 2010 in principle sand cone replacement is more accurate than troxler when carryout field density r sand replacement method is slow as it involve more order to use troxler you are required to calibrate the troxler on site in line with the sand replacement step carryout a sand replacement and the same time just

Cutter method and the sand replacement method 62 sand replacement method 621 introduction the sand replacement method is the most widely used insitu density test although the test takes slightly longer to perform than some other insitu density tests the test may be carried out on most type of materials there are various types of sand

A sand cone apparatus the sand cone apparatus consists of a container for the calibrated sand a conical stopcockcontrolled outlet and a base plate the base of the conical outlet shall have a nominal interior diameter of 6 in 150 mm and shall be flared flat to fit the base plate the base plate and container are matched and

Aug 27 2018 for this the sand apparatus is placed on a flat glass and shutter is opened just to know the weight of sand in the funnel weight of apparatus full of sand w3 8650 gm weight of apparatus with remaining sand w4 8100 gm weight of sand filling the funnel cone w5 w3w4 8650
