The compressive strength of concrete is the most common performance measure used by ... CIP 9, Low Concrete Cylinder Strength. Historical strength test records are used by the concrete producer to establish the target average strength of concrete mixtures for future work.
The word concrete comes from the Latin word "concretus" that means compact or condensed; in fact it is well known that since the second century the Romans mixed quicklime with pozzolan to enhance its hydraulic properties and then mixed it with aggregates in order to obtain a robust stone-like material for the construction of roads and structures.
Apr 02, 2014· Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during production of concrete etc. Test for compressive strength is carried out either on cube or cylinder.
Controls produce a wide range of concrete compression machines from 1500 to 5000 kN of capacity. Select your tester model here. ... Compression machines for strength tests on concrete cubes, cylinders and blocks.
1.1 This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ].
Humboldt's concrete compression frames are designed to handle the daily demands of testing concrete cylinders, beams, blocks and cubes. Humboldt's compression machines span a testing range from 30,000 to 500,000 lbs. (1112 to 2,224kN).
Typical testing includes compressive strength of concrete cubes and cores. We provide an on-site service to facilitate the sampling and making of concrete test cubes as well as a collection service. All cubes are appropriately cured in readiness for testing at our laboratory.
