  2. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested after 28 days (fck). In field, compressive strength tests are also conducted at interim duration i.e. after 7 days to verify the anticipated compressive strength expected after 28 days.

    They had no innate ability to transfer their tactile shape knowledge to the visual domain. However, the experimenters could test three of the five subjects on later dates (5 days, 7 days, and 5 months after, respectively) and found that the performance in the touch-to-vision case improved significantly, reaching 80–90%.

    This test assesses the ability to do cube analysis. To administer this, the administrator points to a three-cube model on the blackboard and has the army recruits count how many cubes there are. He then does the same with a 12-cube model. After demonstrating how the test works, he has the recruits turn to the next page in their books and begin.

    The test was developed in 1920 by psychologist Samuel C. Kohs (1890–1984), a student of Lewis Terman, [3] building on earlier and similar designs (such as Francis N. Maxfield's Color Cube Test). [4] Kohs described the 1920s version of the test as a series of 17 cards which increase in complexity as the test progressed. [5]

    In his article, Miller discussed a coincidence between the limits of one-dimensional absolute judgment and the limits of short-term memory. In a one-dimensional absolute-judgment task, a person is presented with a number of stimuli that vary on one dimension (e.g., 10 different tones varying only in pitch) and responds to each stimulus with a corresponding response (learned before).

    In the cube test, 4 black 1" cubes were placed in a row, each cube separated by 4 inches from its neighbors. The test administrators takes a smaller cube and taps on the 4 1" cubes in increasingly complicated sequences. The test subject is requested, sometimes only by sign language, to repeat the sequence. If the cubes are numbered 1 through 4 ...
