Concrete Block Strength Testing Machine

Humboldt s compression machines span a testing range from 30 000 to 500 000 lbs.

Concrete block strength testing machine.

The testing machine shall be wiped cl ean. Concrete cylinder end grinders are essential tools for modern concrete labs the concrete cylinder end grinders eliminate the need for sulfur or unbonded capping of concrete strength specimens. Used to determine the splitting tensile strength of concrete cylinders. Typically concrete cubes are cured and tested in a manual or automatic concrete compression machine at 7 days and 28 days to assess compressive strength.

The cylinder splitting head has a bearing contact area of 12 304 mm long by 2 50 mm wide its surface is machined plane to 001 025 mm and has a scribed center line of the face of the bar for easier centering of test samples. All compression frames are built in the u s. Concrete paving blocks are ideal materials on the footpaths for easy laying better look and finish. Cored units shall also be measured for minimum thickness of face shells and webs.

Passing ability of self consolidating concrete equipment accessories for consolidation strike off temperature sample handling and initial set determinations. Rebound hammer or schmidt hammer astm c805 method. Models are cost effective time saving reduce health and safety concerns and can prepare four to six specimens at the same time up to 100 4in or 6in 102 or 152mm cylinders per day. Concrete strength testing equipment measures compressive or flexural strength of concrete to assure compliance with specifications.

Humboldt provides a complete selection of concrete testing equipment for fresh and in place concrete structures in accordance with astm aashto and other standards. 1 flexural strength test on paver. From these 3 blocks are to be tested for block density 8 blocks for compressive strength 3 blocks for water absorption. Equipment includes concrete compression machines and accessories cylinder capping pads end preparation apparatus and capping compound masonry block caps and a portable concrete beam tester.

A spring release mechanism is used to activate a hammer which impacts a plunger to drive. The compressive strength testing machine consist of two steel bearing blocks one is in rigid position on which the masonry unit is placed and another one is movable which transmit the load to the masonry unit when applied. Methods for testing compressive strength of concrete 1. Specimens 20 full size units shall be measured for length width and height.

Humboldt s concrete compression frames are designed to handle the daily demands of testing concrete cylinders beams blocks and cubes. If the bearing area of masonry unit is more than the bearing area of steel blocks then separate steel plates are used.
