Product Description

We have earned vast credibility in the market for offering Concrete Permeability Test Apparatus. Due to high demand, we present these products at reasonable costs.

 

Features:

 

• Sturdy construction

• Flawlessly finished

• Low maintenance

• Widely used

• Technically accurate

Product Details:

The Test is applicable to hot mix designs using bitumen and aggregates up to a maximum size of 25mm.  In this method, the resistance to plastic deformation of cylindrical specimen of bituminous mixture is measured when the same is loaded at periphery at 5cm per min.  This test procedure is used in designing and evaluating bituminous paving mixes.  The test procedure is extensively used in routine test programmers for paving jobs.  These are two major features of the Marshall Method of designing mixes namely:

 

a) Density – Voids Analysis

b) Stability – Flow Tests

 

The Marshal Stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60ºC.  The flow value is deformation the Marshall test specimen undergoes during the loading upto the maximum load, 0.25mm units.  In this test  attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.

 

The Apparatus consists of :

v  A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head.  Limit switches are fitted inside to control upward or downward movement of the pillars.  On off reversing switch and indicator lamps are on the front side while a hand wheel to manually move the pillars is on the right.  The load frame has fixed speed of 5.80cm per minute, operated on 230 volts AC.

v  One number Compaction pedal with specimen mould holder.

v  2 Nos Compaction Rammers, 4.5kg weight and free fall 45.7cm.

v  One number Breaking head assembly with provision to fix flowmeter.

Concrete Moulds are easily cast by using a tamping bar or a vibrating table.  However air trapped in cement mortar paste can not be thus removed while casting cement mortar moulds.  Easy method is to impart greater vibration of lesser amplitude to the mould while casting.  This is achieved in a Vibrating Machine.  Vibrating Machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapid hardening Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements.

 

Specifications: 
The machine consists of a vibrating frame assembly and an electric motor mounted on a sturdy base.  The complete frame assembly consists of a vice to hold a 7.06cm cube mould and two studs threaded at top and a hopper to feed the sample in the mould.  This assembly is supported on four springs and has an in built rotating shaft which rotates eccentrically and thus imparts vibrations to the entire frame.  A balance weight is an integral bottom part of the frame.  The centre of gravity of the assembly is brought to the centre of the eccentric shaft or within a distance of 25mm below it.  The electric motor drives the shaft of the frame and thus imparts required vibrations to the mould.  The frequency of vibration is 12000 ± 400 vibration per minute.  Supplied complete with a 7.06cm cube mould and loose base plate, a time switch 0-5mins x 1 min and certificate of vibration.

Product Details:
