NZS 3112.4:1986 PDF Download

The NZS 3112.4:1986 standard provides guidelines for testing various properties of grout. The standard focuses on grout that comprises water and cement only, excluding additional admixtures or materials.

The standard outlines methods for testing flow time, volume change, bleeding, and the molding, curing, and compressive testing of grout. Flow time refers to the time it takes for the grout to flow through a standardized apparatus. Volume change tests assess any alterations in the volume of the grout over a designated time period, providing valuable information on its stability.

Additionally, the standard addresses bleeding, which involves the separation of water from the grout mixture. This is an important characteristic to measure as excessive bleeding can affect the performance of the grout. The standard also provides instructions on the proper molding, curing, and compressive testing of grout to determine its strength and durability.
