ASTM C937-16 PDF Download

The ASTM C937-16 standard is a specification that covers the use of fluidifier for grout in preplaced-aggregate (PA) concrete. This standard outlines the requirements for the grout ingredients, including Portland cement, pozzolan, and fine aggregate composition. The fluidifier used in the grout must meet specific criteria, including reduction in mixing water, expansion, bleeding, increase in water retentivity, initial and final setting time, and compressive strength.

Overall, this standard provides guidelines for the composition and properties of the grout fluidifier used in PA concrete, ensuring consistent and reliable performance. It ensures that the grout meets the specified requirements, which are important for the successful application of preplaced-aggregate concrete. Compliance with this standard helps to achieve desired results in terms of the fluidity, setting time, and strength of the grout, leading to high-quality PA concrete structures.
