ACI SP-82:1984 PDF Download

ACI SP-82:1984 contains 38 papers that cover a range of testing methods for concrete. These methods include surface hardness and penetration resistance tests, pullout tests, ultrasonic pulse velocity tests, break-off tests, and combined testing methods. The publication also discusses maturity techniques for testing concrete strength.

Additionally, the standard explores a variety of nondestructive testing methods for evaluating concrete properties other than strength. These methods include magnetic, electrical, radioactive, pulse echo, radar, microwave absorption, acoustic emission, nuclear, infrared thermography, and permeability testing techniques. The standard provides a global review of in situ/nondestructive testing, offering insights from across the world.

The table of contents reveals that the standard covers a wide range of topics related to in situ/nondestructive testing of concrete. Some of these topics include the study of stress waves in the plunger of a rebound hammer, Romanian achievements in nondestructive strength testing of concrete, estimation of concrete strength using combined testing methods, the evaluation and acceptance of concrete quality by in-place testing, and variability and strength prediction of concrete at early ages. The publication also explores the pullout technique and in situ pullout strength of concrete with inserts embedded by "finger placing."
