The sand replacement test method is used to determine in situ dry density of soil. The procedures, materials, equipment, and specifications of this test is based on the Indian Standard (IS 2720 part 28). This test is of significant importance and it has been widely used in various construction project sites.

This test is done to determine the in-situ dry density of soil by sand replacement method as per IS: 2720 (Part XXVIII) – 1974. The apparatus needed is i) Sand-pouring cylinder conforming to IS: 2720 (Part XXVIII) -1974 ii) Cylindrical calibrating container conforming to IS: 2720 (Part XXVIII) – 1974 iii) Soil cutting and excavating […]

The in-situ density of material is determined by the weight of the excavated material divided by the in-situ volume. The volume of the excavated hole can be determined from the weight of sand with known density filling in the hole. There are several methods for determining the field density of soils: core cutter method, sand replacement method ...

The in-situ density equals the weight of excavated materials divided by the volume of excavated material. Field Density Test – Apparatus. Sand pouring cylinder equipment. Small sand pouring cylinder equipment: this suitable for fine and medium-grained soil. It consists of a cylinder having a diameter of 100 mm and a length of 380 mm with an ...

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. ... The bulk unit in-situ soil is determined from the weight of soil excavated and the volume of the hole. The Wet density or bulk density of soil is computed as:

The present invention relates to method and apparatus for determining in situ the density and fabric or structure of soils, sands, silts, and other materials. More particularly, the present invention provides a method and implementing apparatus for measuring in situ the electrical capacitance and resistance of soil samples at a predetermined ...

An apparatus and a method for determining the cure state of thermosetting polymers using time domain reflectometry. A miniature capacitor is constructed at the end of a coaxial transmission line which is immersed in the curing polymer so that the polymer is the dielectric of the capacitor, and step function voltage pulses are fed to the transmission line, while the reflected signal from the ...

The bulk unit in-situ soil is determined from the weight of soil excavated and the volume of the hole. The Wet density or bulk density of soil is computed as:

An apparatus for cutting soil and constructing sub-surface containment barriers, such as for constructing subsurface containment walls or basins around and under contaminated soils, comprises an elongated beam for abutting an extended length of soil. The beam comprises a cutting assembly that creates a cutting action against the extended length of abutting soil.

APPARATUS REQUIRED . Sand pouring cylinder of 3 litre/16.5 litre capacity, mounted above a pouring come and separated by a shutter cover plate.; Tools for excavating holes; suitable tools such as scraper tool to make a level surface. Cylindrical calibrating container with an internal diameter of 100 mm/200 mm and an internal depth of 150 mm/250 mm fitted with a flange 50 …

(d) Open the valve all the way and let the sand flow freely, being careful not to jar the apparatus while the sand is flowing. When the sand ceases to move in the bottle, close the valve and remove the apparatus. (e) Weigh the sand cone apparatus with the remaining sand to …

A method and apparatus for the in-situ bio-remediation of contaminated soil and groundwater. Perforated piping embedded within the contaminated region delivers a treatment fluid. The treatment fluid is either a mixture of water, contaminant-eating bacteria and nutrients or a chemical mixture of hydrogen peroxide, a catalyst and water.

apparatus onto the base plate and open the valve to allow sand to flow into the test hole. When the sand flow stops, shut off the valve and remove and weigh the apparatus. Do not tap or vibrate the apparatus during this process. The weight obtained is entered on Form IT 625 Line 6 (Final Wt. Apparatus and Sand).

The primary objective of the sand replacement method is to determine the dry density of soil. It is used as a control test to check if the soil has acquired the designated dry density after compaction. The determined in situ dry density is necessary for the design of pavement and highway as well as for the estimation of the quantity of the base ...
