Concrete Facts – 10 Things You May Not Know About Concrete

1) Ancient Greece and Ancient Rome First Used Concrete

Cement was first used in 800 BC in Greece, Cyprus, and Crete, while Rome used concrete from 300 BC to 476 AD. This kind of concrete was made using pozzolana (a form of volcanic ash), pumice and quicklime. Romans used concrete to build structures such as arches, vaults and domes.

2) Concrete - One of the Most Widely Used Materials

Global concrete consumption is double as much as wood, plastics, aluminum and steel collectively. In fact, the United States concrete production industry generates $30 billion per year.

3) Portland Cement Was Named After Portland Limestone

Portland cement is the most standard type of cement used all across the world. It comprises plaster, mortar and concrete. The first patent taken out on this kind of cement occurred in 1824. It was named after Portland limestone as it has the same color. Portland cement production involves the heating of limestone and clay at first, followed by grinding of the material with sulfate.

4) Specific Reactions Behind Cement Production Yet to be Known

Cement is one of the most difficult subjects being explored within materials science. Materials scientists are still not able to understand the specifics behind the reactions taking place during the mixing of cement powder and water. They have only hypothesized the specific reactions behind cement production.

5) Concrete Expansion Joints Critical in Designing Process

Concrete expansion joints or isolation joints are vital in mitigating the effects of cracking. The use of expansion joints enables independent horizontal and vertical movement between various parts of the structure as the material shrinks, thus minimizing cracking.

6) Average Concrete Slab Weighs 145 Pounds Per Cubic Foot

Concrete weight varies with its air and water/moisture content, with cement density between 52 to 103 lb/cu. ft. The weight of the average concrete slab is roughly 145 lb/cu. ft, while the density of lightweight cement is 116 lb/cu. ft.

7) Safer Alternatives for Concrete Production

Environmental scientists at CSHub find ways to mitigate the carbon dioxide and greenhouse gases problem resulting from concrete production. One of the objectives includes lowering the roasting temperature during cement production in order to burn less fuel. Ceretech, a cement company, has already started utilizing fly ash as an eco-friendly material for cement production. Fly ash is generally ended up in landfills. Concrete recycling is gaining interest because of increasing environmental awareness. This includes the garner of the material from demolition locations and processing it in a crushing machine.

8) It is Necessary to Determine the Strength of Concrete Material

Utility companies, construction managers and others utilizing concrete must test their materials in accordance with ASTM C1609, ASTM C469, ASTM C109, ASTM C78, and ASTM C39 specifications. They are seeking materials testing machines that can perform static, flexural, and compressive modulus of elasticity testing. Most of them are selecting universal testing machines to fulfill their requirements.

9) Servo Controlled Testing Machines from ADMET to Measure Compressive Strength of Concrete as per ASTM C39

ADMET is a provider of servo controlled concrete compression testing machines with a capacity ranging between 20,000 and 600,000 Lb. Driven by the MegaForce Pump, these testing machines are an economical solution to perform error-free automatic testing of concrete cubes, beams, and cylinders. ADMET helps companies that already have concrete compression testing machines to save some money by retrofitting MegaForce to their existing machines.

10) ADMET Testing Systems to Measure the Flexural Performance of Fiber Reinforced Concrete as per ASTM C1609

First-peak strength is a measure of the flexural behavior of fiber-reinforced concrete till the point at which the material begins to crack. Residual strengths at specified deflections describe the residual capacity of the material after cracking. Specimen toughness characterizes the energy absorption capacity of the material. Each of these mechanical properties gains significance based on the required applications. An ASTM C1609 test requires extra care in the setup and execution to ensure the accuracy of the results. It can be achieved with ADMET eXpert 2600 series dual column testing machines supported with the the MTESTQuattro materials testing software.


ADMET Inc., a provider of integrated materials testing systems based in the metropolitan Boston area, is offering universal testing machines (UTMs), digital indicators and controllers, and specialized grips and fixtures in China and Southeast Asia. The company sells direct and through qualified representatives to serve manufacturing and construction, as well as university and government research. It sells new equipment, and retrofits virtually any manufacturer's testing machines.

"ADMET testing systems are important elements in meeting internationally certified quality standards," commented Richard Gedney, ADMET founder and president. "We can help researchers and manufacturers evaluate and certify products. Our pre-programmed test procedures, simple interface and data-based reporting results make it easy for operators to run the equipment."

ADMET's universal testing machines perform a range of materials characterizations using tensile, compression, shear and bend tests. The company's equipment is used to test concrete, metals, alloys, plastics, rubber and textiles, as well as medical and biomechanical materials and products. They are sold under the ADMET name and are also private-labeled to other materials testing machine suppliers.

ADMET offers a full range of products from MEMS device testers that measure 10 microNewtons, through low-force tabletop devices, to large models that test up to 600 kiloNewtons. Products meet or exceed applicable international standards, including standards issued by ASTM, BSENISO, DIN, ISO, JIS and others.

ADMET sells both new and used machines. It develops controller hardware and firmware, as well as Microsoft Windows-based materials testing systems. It also offers retrofit/upgrade packages for virtually any manufacturer's testing machine, including Amsler, Baldwin, Denison, ELE Soiltest, Instron, MTS, Mohr & Federhoff, Reihle, SATEC, Shimadzu, Tinius Olsen and Zwick.
