A set of three moulds as per IRC - SP-53-2002 Made of brass /Gunmetal with the shape, dimensions and tolerances as shown in fig 1. The ends b & b` are known as clips, and the parts a & a' are known as sides of the mould. The dimensions of the mould shall be such that when properly assembled it will form a briquette specimen having the following dimensions.

Total Length : 75 0.5 mm

A = 36.5 0.1 mmB = 30.0 0.1 mmC = 17.0 0.1 mmD = 10.0 0.1 mmE = 10.0 0.1 mm

The main purpose of the soundness test is to assess the possible risk of late expansion due to hydration of uncombined calcium oxide and/or magnesium oxide. The test uses apparatus known as Le Chatlier apparatus, which magnifies any expansion during heating to a value that can be measured.

The apparatus consist of a small split cylinder of spring brass or other non-corrodible metal of 0.5 mm thickness forming a mould 30 mm internal diameter and 30 mm high. On either side of the split, two indicators are brazed suitably with pointed ends made of 2 mm diameter brass wire in such a way that the distance of these ends to the centre of the cylinder is 165 mm. The split cylinder will be kept between two glass plates.

Water bath capable of containing immersed Le-Chatlier moulds with specimens and of raising their temperature from 27' deg _+ 2'deg C to boiling in 27 +/- 3 minutes.
Made of double walled, Outer made of CRC Sheet powder coated or stainless steel and inside made of stainless steel. Gap between the wall filled by glass wool to avoid heat losses. Temperature is controlled by sensitive thermostat and temp. read on Glass Thermometer or DIGITAL Temp. Indicator cum controller with timer programmed to achieve boiling temp. in prescribed time. The bath is suitable to accommodate six moulds at a time. Complete with stand to hold Le-Chatlier moulds in prescribed method. Complete with three core wire and 15 Amp. Three pin top,

Cubes of fresh concrete are made to test a variety of properties on the eventually cured and hardened concrete. Fresh concrete is subjected to a standard compaction regime in the cube mould and is then normally initially cured under specific laboratory conditions. The moulds are manufactured, subject to tight dimensional, hardness, square ness and surface finish requirements.

Complete with base plate. The faces of the mould are machined flat to +/- 0.02mm accuracy and finished to within +/- 0.2mm of specified dimensions. Material for construction of moulds is Cast Iron or Mild steel. The moulds are stout enough to prevent distortion and facilitate the removal of the moulded specimen without damage. The Moulds are so machined that when they are assembled ready for use, the dimensions and internal faces are accurate within the specified limits. Internal faces of the moulds are smooth.
The base plate is attached to the mould by cleats .The parts of the mould, when assembled, are positively and rigidly held together during filling, subsequent handling and vibration where applicable.
SIZES AVAILABLE : 50MM/ 100MM/ 150MM

SPANNER FOR DEMOULDING AND MOULDING, TAMPING ROD WITH SAUQRE FACE.

As per IS : 10086-1982, The cube mould is so constructed so as to facilitate separation into two parts. The mass of the mould together with the base plate will be 2.8 +/- 0.2 kg. Material for construction of these moulds is mild steel.

For casting concrete specimens for flexural tests. The mould is made of 4 plates assembled together. Each mould with base plate, made of Mild Steel. Faced are machined flat to +/-0.2mm and finished in size to 0.2mm. AS PER IS: 516
