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.

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.

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.

Dimensions	Cm.
Bottom diameter	20
Top diameter	10
Height	30

The Cone is constructed of metal of at least 1.6 mm thickness and the top and bottom are open and at right angles to the axis of the cone. The mould have a smooth internal surface and provided with suitable foot pieces to a base plate and also handles to facilitate lifting it from the moulded concrete test specimen in a vertical direction as required by the test. The base plate is provided with cleats & swivel handle.

The Vibrating table is entirely constructed of thick steel. The table top is made of thick mild steel plate and has stops along its edges to prevent moulds from walking off the table during operation. A cross arm adjustable on a vertical rod at the centre of the table is provided to hold the moulds while operating the table. The variable pitch pulley arrangement permits the variation of frequency between maximum of 3600 vibrations down to 2600 vibrations per minute. A speed regulation handle is provided for increasing or decreasing the frequency. The vibrator is mounted on cushioned steel vibrating deck. A switch is provided for starting the motor. Operation on 440 V, three phase, A.C. supply

The strength of concrete is generally estimated after 28 days by crushing field test cubes or cylinders made from the representative concrete used for the structure. The utility of ascertaining strength after 28 days is often questioned since by this time considerable concrete would have been placed and work may have progressed. It is then rather too late for remedial measures. It is therefore of tremendous advantage to predict 28 days strength within a few hours of casting the concrete so that, we have a good idea about the strength of the concrete.

The rate of gain of strength of concrete depends on the reaction rate of cement and additions with water (Hydration). In common with all chemical reactions, the rate of reaction depends on reaction of temp. Higher reaction temperature gives higher rate of reaction e.g. the concrete gains strength more rapidly when its temp. is higher. Accelerated curing is the process by which the temperature of the concrete is raised artificially by applying external heat to speed up the rate of gain in strength.

The test method covers procedures for curing test specimens of concrete stored under conditions intended to accelerate the development of strength. The procedures are: Procedure A- Warm Water Method, Procedure B-Boiling Water Method

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.

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.

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.

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.
