30. tures These recommendations were made as addition to GOST 17624 87 and have the main rules of testing the compressive strength of concrete in monolithic structures with the help of surface sounding method Application of surface sounding method 1 The method of surface sounding be used for testing the concrete s solidity at the moment when the cast formwork is taken off or for testing the concrete s solidity in terms determined by the project or technical documentation and also it can be used for engineering monitoring of exploitable or reconstructed monolithic structures 2 The concrete s solidity is detected by the following experimentally established calibration dependences Velocity of ultrasound dissemination at surface sounding concrete s solidity and time of ultrasound dissemination at surface sounding concrete s solidity 3 Surface sounding can be used for testing solidity both of heavy and light concrete of 7 5 to B50 types the calibration dependences should meet the demands described in the item 9 of Preparations for Testing of this Instruction see below 4 Ultrasonic Testing can be made with the help of devices that meet the requirements of Standard GOST 17624 87 of RF and that can provide time and velocity measurements of ultrasound dissemination on 120mm base or larger Is recommended to use the probes with dry point contact for example UK1401 Preparations for Tes
