CEMENT TESTING EQUIPMENTS

To determine the fineness of cements, pozzolanas and other powdery materials, various international specifications recommend the use of "specific area" method.

The procedure, as recommended in various standards, is for determining the quantity of water required to produce a cement paste of standard consistency.

It is used for the determination of soundness by expansion method of ordinary and rapid hardening Portland cement, low heat Portland cement and class 'A' Limes.

Double walled inner chamber in stainless steel outer chamber in mild steel temperature range Ambient to 100°C controlled by capillary thermostat.

Used for finding specific gravity of hydraulic cement. Made from Borosilicate glass. The flask is 243mm in total height, having a bulb of 90mm dia of 250ml approximate capacity.

ASTM C 151 also specifies the use of shrinkage bar moulds for the determination of soundness. Length Comparator listed in the concrete section determines the change in length of the specimen.

The apparatus consists of a frame with adjustable cross plate and a recessed seating and a 300 ± 1.0 mm long alloy steel reference bar

It consists of a stainless steel cylinder with an insulated cover, mounted on a sturdy supporting frame, enclosed in a heat insulated metal housing, attractively finished.

This equipment is required to determine the heat of hydration of cement as expressed in calories per gram.

The Flexure Strength Testing Machines are designed to provide maximum rigidity throughout their working range.

However air trapped in cement mortar paste can not be thus removed while casting cement mortar moulds.

The apparatus consists of an epicyclical type stainless steel paddle imparting both planetary and revolving motion, by means of gears.

For making standard rectangular specimens of 40 x 40 x 160mm. of Portland and pozzolana cement mortar for determining the transverse strength.

Water proofing of these compounds, is established by measuring permeability of standard mortar.

The flow table consists of a 30 cm dia polish steel plate with 3 engraved annular circles 7, 11 and 19cm dia.

It is used for determining the flow of cement concrete. Consists of a steel table top 76.2cm (30 inch. Dia) Finely machined.

This used for measuring the consistency of pozzolana and also cement mortar and hydrated lime.
