Australian Standard (AS3799) Curing Compounds Explained.

In Australia, curing compounds are used in construction and concrete works to ensure proper hydration and curing of concrete, which enhances its strength and durability. 

AS3799 is the Australian Standard that specifies requirements for curing compounds. It outlines different classes and types of curing compounds based on their composition and performance characteristics. Here's an explanation of the different classes and types:

CLASSIFICATION Curing compounds can be classified as follows:
Class A Wax-based compounds.
Class B Hydrocarbon resin-based compounds.
Class C Chlorinated rubber-based compounds.
Class D Synthetic polymer compounds.
Class Z Other membrane-forming compounds

Curing compounds are grouped into types by appearance, as follows:
Type 1 Clear or translucent without dye.
Type 1-D Clear or translucent with fugitive dye.
Type 2 White pigmented or containing aluminium reflective pigments.
Type 3 Black or coloured, other than white.

It's important to note that AS3799 sets requirements and guidelines for curing compounds to ensure they meet certain performance standards and are suitable for use in various concrete applications. Contractors and construction professionals should select curing compounds that are appropriate for the specific project requirements and environmental conditions. Additionally, proper application and curing procedures should be followed to ensure the effectiveness of the curing compounds in promoting concrete strength and durability.
