Test Method Title
Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)
Reference Number
ASTM C109
Material
Mortar
Test Property
compressive strength
Description of Test
The mortar used consists of 1 part cement and 2.75 parts of sand proportioned by mass. Portland or air-entraining Portland cements are mixed at specified water/cement ratios. Water content for other cements is that sufficient to obtain a flow of 110 6 5 drops of the flow table. Two-inch or [50-mm] test cubes are compacted by tamping in two layers. The cubes are cured one day in the molds and stripped and immersed in lime water until tested.
Number of Test Specimens
2-3 specimens per batch per age
Test Specimen Size
2" x 2" x 2"
