The Evolution of Concrete Testing: From Concrete Cubes to Wireless Sensors
1/3 Traditional method: When concrete is poured, contractors cast cylinders or cubes (2 sets).
• One set cures in a lab (standard 20°C/100% RH).
• The other cures on-site.
Samples are later crushed in a compression machine to measure strength at 7, 14, or 28 days.
Simple… but seriously outdated.
