Pace Rate Controlled Compression Testing Machine, A pace Rate Controlled Compression Testing Machine is a testing machine that is specifically designed to evaluate the resistance of materials and products to compression forces. It has been designed in such a way for reliable and consistent unconfined testing of concrete samples. Pace Rate Controlled Compression Testing Machine is one of the most fundamental types of machines for material testing with properties like tensile strength, elastic limits, and many more. These compression tests are used to determine material behaviors under compressive pressure loads.
