Clay Soil Casagrande Grooving Tool Liquid Limit Test from www.alibaba.com
The plastic grooving tool is used to control the width of the soil groove in the liquid limit cup. Using the grooving tool, cut a groove at the center line of the soil cup. Atterberg limits (liquid limit testing) liquid limit testing determines the water content at which soil changes from a liquid to a plastic state.
Clean And Check The Liquid Limit Device To See That It Is In Working Order.
A soil sample placed into a cup in the machine separates into two halves using a grooving tool. A soil is place in the grooving tool which consists of a brass cup and a hard rubber base. The casagrande tool is recommended for normal fine grained soils.
At This Limit, The Soil Possess Low Shear Strength.
The following materials are required for conducting atterberg limits tests. Atterberg limits (liquid limit testing) liquid limit testing determines the water content at which soil changes from a liquid to a plastic state. Using the grooving tool, cut a groove at the center line of the soil cup.
It Determines The Water Content At Which Soil Changes From A Liquid To A Plastic State.
Ii) level the mix so as to have a maximum depth of 1cm. Features a spirit level for maintaining a level testing position. At this limit, the soil possess low shear strength.
The Liquid Limit Is The Moisture Content At Which The Groove, Formed By A Standard Tool Into The Sample Of Soil Taken In The Standard Cup, Closes For 10 Mm On Being Given 25 Blows In A Standard Manner.
Cutting a groove at the middle of the soil paste with a standard grooving tool; The grooving tool should be drawn in an arc and perpendicular to the surface of the cup through its movement. A combined grooving tool and gauge as described in aashto t 89.
3.3.2 Using Tlje Gauge On The Handle Of The Grooving Tool Or A Separate Gauge And By Means Of The Adjustment Plate Of The Mechanical Liquid Limit Device, The Height Through Which The Cup Is Lifted And Dropped
The plastic grooving tool is used to control the width of the soil groove in the liquid limit cup. Use a gauge or the handle of the grooving tool and the adjusting plate of the liquid limit device (casagrande) such that the cup falls exactly 10 mm for one revolution of the handle. The liquid limit set performs atterberg or liquid limit tests in accordance with astm specifications.
