This test is used to determine the compressive strength of a concrete cube, which has usually been made from fresh concrete cast in a standard test mould. The value of compressive strength can then be used to assess whether the batch that the concrete cube represents meets the required compressive strength. Following cube manufacture and curing, which should both be closely controlled, the cube is crushed at a stated constant speed until it can sustain no further increase in load. The strength is then derived by calculation using the maximum load and cube dimensions.
The machine embodies an hydraulic system designed to meet the requirements of Indian standards Specification 516-1959 for compression tests on concrete cubes up to 20 cm X 20 cm X 20 cm. and also concrete cylinders up to 30 cm height. Using special platens and fixture, Brick testing and flexural testing can also be carried out on the same machine.

Often, existing concrete structures will need to be examined and tested to ensure the concrete remains of adequate strength and durability. Rebound hammer surveys can be conducted to provide a rough estimate of concrete strength, where it is not possible to determine this by more accurate means such as core extraction and testing.
The test involves using a special rebound hammer, which measures the recoil of a piston against the concrete surface when a standard force is applied. This recoil can then be correlated approximately to concrete strength.
General Description SpecificationsThe rebound hammer consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar. A plunger is attached to the guide bar which is pressed against the surface to be tested. As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent, according to the strength of the surface, which is indicated by a rider on a calibrated scale. A lock button fixed on the body of the hammer lock the rider in place and the rider can be reset to zero Position by using the same button. The equivalent compressive strength can be computed from the chart supplied. It is suitable for specimen of compressive strengths 100-700Kg/cm. The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.

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

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 Descripation SpecificationsTThe 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.

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 Description SpecificationsThe set up consist of permeability cell, water reservoir and pressure lines, with glass bottles.
Permeability CellConsists 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.
