ASTM Standards

 Throughout the semester we have mentioned the many different governing ASTM standards associated with material testing. One such test that we performed in lab was related to ASTM C143 “Standard Test Method for Slump of Hydraulic-Cement Concrete.” Quite often the testing procedure from the ASTM standard have been simplified and included as the procedure in the textbook (Somayaji, Civil Engineering Materials). For this problem, review the actual ASTM standard and compare it to the simplified procedure covered on page 208 of the materials textbook (CON-1: Slump Test of Portland Cement). What are the similarities and difference between the actual ASTM C143 standard and the procedure outlined in CON-1. Are there any items removed in the simplified procedure that are discussed in the actual standard? Be sure to give specifics.
