| Introduction | The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The oven dried and accurately weighed aggregates are subjected to crushing test on compression testing machine and weight of the resultant fines passing the specified IS sieve to the total weight of the sample expressed a s a percentage is defined as Aggregate Crushing Value. The apparatus is available in three size 75mm dia for 1/8 to size aggregate, 150mm dia for 3/8 to aggregate (standard) and 300mm dia for 1 to 2 aggregate. |
| General Description & Specification: | Consists of Case hardened Mild steel cylindrical container of 150mm dia+0.5mm x 130mm to 140mm high with base plate 200 to 230mm square x 6mm thick. A plunger of 148mm+0.5mm dia x 100 to 115mm high. All parts directly coming in to contact with the specimen during the test are made of mild steel duly case hardened. Supplied complete with tamping rod, 16mm dia x 600mm long, one end rounded. |
| Optional Accessories: | The following accessories are not part of the standard supply and are supplied at an extra cost. |

| Introduction | Used for tablets to determine the durability at the time of production. A transparent plastic persperx drum with cover also a shaped radial fixed blade which carries the tablets alongwith it upto the central height and lets them off while the drum is rotating, thus the tablet rub against each other without any hard impact. The drum rotates at a fix speed of 30 RPM by a geared motor. The rotation period is determined by a Electric Timer. Tablets are weighed before and after the test and the difference in weight for a perticular time period indicating the rate of abrasion. Complete with Electric Timer with neon indicators fitted on a panel. |

| EIE-912, Soxhlet Extraction Heater : Mantle Type : | This apparatus is suitable to heat Soxhlet flasks The heating element is attached to fiber glass yarn-knitted fabric to provide flexible support to bottom of the flask. Glass wool insulation is used below the elements in the housing which is phosphated and powder coated attractively. In the event of spillage the solvent will either evaporate or escape through the drainage hole below each element. The housing has two retort rods and a cross bar on which the extraction apparatus has a built-in regulator which controls the heaters. The heating elements have individual on/off switches and a pilot lamp to indicate working of the elements. The apparatus requires a 230 Volts AC single phase supply. Without glass parts and clamps.

| Introduction | The compaction factor is defined as the ratio of the mass of the concrete compacted in the compaction factor apparatus to the mass of the fully compacted concrete. It involves dropping a volume of concrete from one hopper to another and measuring the volume of concrete in the final hopper to that of a fully compacted volume. The results of the compaction factor test can be correlated to slump, although the relationship is not linear. This test is difficult to run in the field and is not practical for large aggregates (over 1 inch) Compared to the slump test, the apparatus is bulky and a balance is required to perform measurements. |
| General Description & Specification: | The apparatus, consist of a rigid frame that supports two conical hoppers vertically aligned above each other and mounted above a cylinder. The top hopper is slightly larger than the bottom hopper, while the cylinder is smaller in volume than both hoppers. To perform the test, the top hopper is filled with concrete but not compacted. The door on the bottom of the top hopper is opened and the concrete is allowed to drop into the lower hopper. Once all of the concrete has fallen from the top hopper, the door on the lower hopper is opened to allow the concrete to fall to the bottom cylinder. The excess concrete is carefully struck off the top of the cylinder and the mass of the concrete in the cylinder is recorded. This mass is compared to the mass of fully compacted concrete in the same cylinder achieved with hand rodding or vibration. Complete with trowel and tamping bar 0-60 cms long X 16mm dia. |

| Introduction | The equipment is assembled in a mild steel cabinet attractively painted. A central shaft carries a platform with the glass cylinders of 50 ml. each. The platform with the glass cylinders moves up and down at 30 strokes per minutes through a distance of 5 cm and strikes on rubber cushioned bed. Electrically operated, supplied with time switch 0-15 minutes. |
| Introduction | The oldest, most widely used test for determining workability. This test is used to determine the workability of fresh concrete, which would normally be undertaken at the point of delivery to ensure the concrete, is of adequate consistency for placement. The test is applicable to concrete of medium workability. | |||||
| The device is a hollow cone-shaped mould. The mold is filled in three layers of each volume. Each layer is rodded with a 16mm steel rod 25 times. The mould is then lifted away and the change in the height of the concrete is measured against the mould. The slump test is a measure of the resistance of concrete to flow under it own weight. | ||||||
| General Descriptions & Specifications | The apparatus comprise of a slump cone with handles made of mild steel sheet, a chrome plated steel tamping rod of 16 mm diameter X 600 mm long, rounded off at one end, with a scale marked on it and a steel base plate with a carrying handle. | |||||
| The mould for the test specimen will be in the form of frustum of a cone having the following internal dimensions as follows

| Introduction | Complete aluminium die cast model. Attractively painted. Aluminium block accepts 3 capillaries and a mercury thermometer, Max. temperature about 300 deg. C. Fitted with energy regulator. The samples are illuminated by and viewed through a magnifying lens. |
| Introduction | A concrete structure is considered to be of adequate durability if it performs in accordance with its intended level of functionality and serviceability over an expected or predicted life cycle. Concrete durability depends largely on the ease (or difficulty) with which fluids (water, carbon dioxide, oxygen) in the form of liquid or gas can migrate through the hardened concrete mass. Concrete is a porous material. Therefore, moisture movement can occur by flow, diffusion, or sorption. We are concerned with all three, but generally the overall potential for moisture in concrete by these three modes is referred to as its permeability. |
| General Descriptions & Specifications | The set up consist of permeability cell, water reservoir and pressure lines, with glass bottles. |
| Permeability Cell | Consists of a metal cylinder with a ledge at the bottom for retaining the specimen, a flange at the top, removable cover plate and a funnel. A rubber gasket is seated in matching grooves, between the cell and the cover plate, to render the joint water tight. Internal working size of the cell will be 100mm dia X 100mm hight. |
| Water Reservoir | Consists of a length of metal pipe, 50 to 100 mm in diameter and about 500 mm long. The reservoir fitted with a graduated side arm gauge-glass for admitting water and compressed air and a cock for drainage, bleeding and connection to the permeability cell. |
| Pressure Lines | Heavy duty armored rubber hose with end fittings. Complete with glass bottles but without compressor. For specimen size 100 X 100 mm |
| Concrete permeability tester for three specimen of (100mm dia x 100mm height) or (150mm dia x 150mm height) or (150mm cube) is also available.Relavant Standard : IS : 3085 | |
