Description:
It Consists of two frames for clamping to by means of five tightening screw with a hardened end tampered end. Two spacer hold the two frames in position. A pivot rod rests on pivot screws. A dial gauge, fixed to a bracket fitted to the top frame is used for taking deformation measurement. Supplied complete with dial gauge 0.002mm x 5mm in a nice wooden carrying case.

Digital Compression Testing Machine is of rated 2000 kn capacity is fixed to the base. The upper platen has got a self-aligning action and is attached to a screw, which passed through the crosshead plate, and can be raised or lowered for initial clearance adjustment. The lower platen rests on the jack ram and is positioned with the help of a centering pin. Loading is accomplished by upward movement of lower platen. A dust cover is provided on the jack to prevent any dust from going into the cylinder. A spacer with a centering locating pin is provided to test small specimens. The lower and upper platens of the machine are hardened ground and polished. Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.

• 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.

The temperature is indicated and controlled by a DIGITAL auto tuning PID Temp. Controller with soak timer to control the duration of heating and then to shut down the system without manual attendance. The front panel will have power supply indicating lamp, control action indication lamp and one main switch.

Temperature of concrete at the time of placement is important to control and to avoid many possible difficulties. In hot climates, it is important to measure the temperature of the fresh concrete to ensure it is not too hot, which could cause flash setting and rapidly reducing workability. Measurements are generally taken at the point of placement.
