ASTM C305 is the practice for mechanically mixing hydraulic cement pastes and mortars of plastic consistency. To match this to your program, talk with our team.
What ASTM C305 Covers
It standardizes how cement paste and mortar are mixed so that strength and other test specimens are prepared consistently, controlling a key source of variability.
How the Test Is Run
Cement, water, and sand are combined in a defined mixer at set speeds and times to produce a uniform paste or mortar of plastic consistency ready for casting test specimens.
Why It Matters
Consistent mixing is essential for reliable cement and mortar strength results, since mixing affects the specimens fed to strength tests.
