The wear per age due to friction with steel balls is determined and is known as the abrasion value.
Dec 19, 2019 This percentage is known as a crushing value of aggregate. This percentage should not exceed 30 of the total weight of aggregate taken for the test. The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and, in case of other structures it may be permitted up to 45.
Standards. BS 812112. General Description. The Aggregates Impact Value AIV Apparatus is used to determine the aggregate impact value which provides a relative measure of the resistance of an aggregate to sudden shock or impact.

May 20, 2019 The 6th edition of the APA style manual American Psychological Association, 2010 states the following on the topic of reporting p-values When reporting p values, report exact p values e.g., p .031 to two or three decimal places. However, report p values less than .001 as p .001. The tradition of reporting p values in the form p .10, p .05, p .01, and so forth, was appropriate ...
