ASTM C243-95 PDF Download

ASTM C243-95 is a standard test method utilized for determining the bleeding rate and bleeding capacity of cement paste and mortar. Bleeding is a phenomenon in which water separates from the cementitious material and rises to the surface, resulting in the formation of a layer of water on top of the material. This test method aims to measure the rate at which bleeding occurs and the volume of water being bled.

The standard provides guidelines on how to perform the test and obtain accurate results. It is essential to determine bleeding characteristics as excessive bleeding can lead to various issues, including reduced durability and strength of the concrete. By utilizing this standard, engineers and researchers can assess the bleeding properties of cementitious materials and optimize their mixture proportions to ensure optimal performance and long-term durability.
