3 Overview

Test mode is mainly used for the production of mechanical properties testing concrete, cement mortar and other specimens. By controlling the tryout Basic dimensions deviation measurement of performance, to ensure the geometry of the specimen, accurately reflect the physical concrete, cement and other materials performance. Concrete tryout generally by the side mold, a bottom mold and fasteners and other components, usually made of cast iron, steel or engineering plastics. Cube shape can be divided according to their test mode (see Figure 1), prism test mode (see Figure 2), a cylinder test mode (see Figure 3), Body tryout round table (see Figure 4). Their coupling can be divided into single test mode, triple tryout. The basic dimensions are shown in Table 1.
