Site Testing of Construction Materials

Materials arrive on site with certificates, and a certificate describes what left the factory rather than what reached the pour. This guide collects the common site tests in one place: what each one actually measures, how a sound sample is taken for it, how its result is calculated in numbers, and what that result means when the acceptance decision falls due. The testing plan and its frequencies, taking a sample that represents what it claims to represent, soil and fill from Proctor to field density and degree of compaction, aggregates and their grading, fresh and hardened concrete with its cubes and cores, steel and blockwork, asphalt, and then reading the result statistically and deciding to accept or reject. 10 fully worked examples, every number checked.
