The digital compression testing machine with dedicated universal computer software for reading purpose, self operating & monitoring has been designed to meet the need for a simple, economic and reliable means to test concrete / cubes etc. For its compressive strength. The design expressive of simplicity, both of construction and operation, makes the machine easy to use and maintain. The unit is compact, making it useful for site and
Laboratory applications.
Features:
•High stability four pillar load frame.
•Each frame tested for stability and alignment to avoid tension failure during a test and to ensure centre loading.
•A precise large diameter spherical upper platen for optimum results.
•Motorized hydraulic power pack or pumping unit with rapid approach and automatic over load protection.
•Comes standard with safety guards on all four sides
The complete unit comprises a loading unit which is of four pillar model construction having a cross-head with a spherical seated platen. The lower platen is attached to the top of the piston. The loading capacity is of 2000 kn, cubes up to 200 mm & cylinders up to 150 mm dia x 300 mm height can be tested using the appropriate spacers.
Pumping unit attached to the loading unit by high pressure hydraulic flexible hose pipe. The pump facilitates rapid approach of the platens for daylight closure and also provides comprehensive control over the application of load.
A control valve provides fine control over the loading rate for accurate pacing.
Maximum load is held and retained for approx. 15 min, unless cancelled, using the panel mounted reset switch. Pace rate set for running the test can be maintained manually.
200 tones in different models. Portable models are very convenient and useful for site use where carrying frequently the specimens for testing in a standard laboratory is inconvenient and uneconomical. With special attachments, the machines can also be used for bricks, hallow or solid concrete blocks, using appropriate capacity machine. In general compression testing machine consists of a load frame with suitable platens and a pumping unit with pressure gauge, either hand operated or electrically-cum-hand operated. Load frame and pumping unit are connected by pressure pipes.
1. Introduction and test principle of compression strength measuring
The compression testing machine is to measure compression strength of corrugated boxes in the situation of pressure and protect functions of packages for the objects filled in the packages.
Test principle:
(1) Corrugated boxes compression strength test, loading to the corrugated boxes using a compression testing machine at a certain constant rate untill corrugated boxes are broken or till certain load or displacement are reached.
(2) Corrugated boxes stacking test, loading a certain force to the corrugated box using a compression testing machine untill corrugated box is broken or sustain a certain time period.
When measuring deformation of corrugated box during compression test, an original load should be set as a datum point. The datum point can refer to the following chart:
Average compression force(N)Original force(N)
101-200 10
201-1000 25
1001-2000 100
2001-10000 250
10001-20000 1000
200001-100000 2500
2. Functions of compression testing machine
This machine is applicable to metal, cementing compound, tubes, sectional bars, aerospace, petrochemical, waterproof rolls, wire and cable, textile, fiber, rubber, ceramics, food, mechanical packaging, geo-textile, film, wood, paper and other industries and quality supervision department, and it also can be used in college for teaching demonstration.

1.Applications
This cement mortar flexural and compressive strength testing machine is for determining the flexural and compressive strength of moulded mortar specimens. The flexural strength of mortar is determined by three point loading of hardened moulded mortar prism specimens to failure. The compressive strength of the mortar is determined on the two parts resulting from the flexural strength test.
2.Size of mortar for flexural strength test
Cement prism specimen: 40x40x160mm
3.Brief introduction of cement flexural and compressive strength test procedure
Cement flexural strength test
1)place the cement prism in the test machine with one side face on the supporting rollers and with its longitudinal axis normal to the supports.
2)select the apply rate and apply the load vertically by means of the loading roller to the opposite side face of the prism until fracture.
3)keep the prism halves damp until tested in compression
Cement compressive strength test
1)center the prism halves laterally to the platens of the testing machine.
2)increase the load smoothly at a set rate over the entire load application until fracture.
The PARSROS Automatic range of single testing chamber and double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples. These compression and flexure testers are the results of continuous applications and research studies to upgrade the machines with the latest technologies and conform the current standards EN 196-1, 459-2, 1015-11, 13454- 2; ASTM C 109, C348, C349 and BS 3892-1, 4551-1 in terms of its technical properties taking into account client requirements by using suitable accessories.
