Described here are surface preparation methods, tools, and standards, as well as work that is unique to concrete substrates, such as measuring moisture content and dewatering. Repair procedures and materials, which respond to the propensity of concrete to cracking and spalling, and the corrosion of rebar, are also covered.
METHODS OF SURFACE PREPARATION Depending upon conditions of the concrete one or more methods of surface preparation may be required. It is common for decontamination to precede mechanical preparation, and if necessary a second decontamination to follow.
Methods of testing concrete Method 2: Preparation of concrete mixes in the laboratory PREFACE This edition of this Standard was prepared by the Standards Australia Committee on Methods of Testing Concrete as part of its ongoing program to revise the AS 1012 series of Standards on the testing of concrete. It supersedes AS 1012.2—1983.

ASTM C1583 / C1583M (Standard Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension — Pull-off Method) describes a test method that can be used to indicate the adequacy of the surface preparation.
Jan 03, 2017· Foam concrete preparation Yu Song. Loading... Unsubscribe from Yu Song? ... The fresh foam concrete comes from a process of continuously mixing foam and paste until an even mixture is obtained.
ICRI also indicates which methods of surface preparation can be used to render the indicated concrete surface profile. Abrasive blasting is one of the most versatile methods, covering a wide range of surface profiles, from CSP 2 to 7.
The simplest methods available are often just indicative, qualitative tests that highlight the presence of moisture during concrete preparation, rather than the amount. Notably, the Plastic Sheet Test is one of the easiest to complete, which involves securely attaching an approximately 18in 2 (0.01m 2 ) plastic sheet to the concrete for 24 hours.
