May 04, 2013· Overview Compressive strength of cement is determined by compressive strength test on mortar cubes compacted by means of a standard vibration machine. Standard sand (IS:650) is used for the preparation of cement mortar. The specimen is in the form of cubes 70.6mm*70.6mm*70.6mm. Apparatus Measuring Instruments NAME CAPACITY / RANGE / SIZE ACCURACY / LEAST COUNT Cube …
Sep 05, 2014· Good quality construction material makes your home look beautiful inside out. Watch our video to learn the various ways to test the comprehensive strength of concrete.
for Compressive Strength Testing of Grouts and Mortars T 813 f. Bring in the mortar that has been forced out onto the tops of the molds with a trowel and smooth off the cubes by drawing the flat side of the trowel (with the leading edge slightly raised) once across the top of each cube at right angles to the length of the mold. Then, for

Cube Testing. The cubes are generally tested at 7 & 28 days unless specific early tests are required, for example to remove a concrete shutter safely prior to 7 days. Usually 1 cube will be tested at 7 days and 2 cubes at 28 days, however this may vary depending of the requirements, check the design first.
ASTM C109/C109M. Since the mortar as described is of a stiffer consistency than that used in cement testing, particular attention shall be given to make sure that the mortar is thoroughly consolidated in the molds. 5.

ANSWER: Mortar is typically specified to meet the "proportion specification", which is the default in ASTM C270. The only circumstance in which mortar cube testing is required is when the mortar has been specified by the "property specification" and the proposed mix design must be verified to meet the property requirements of ASTM C270.

Nov 01, 2009· A common mistake made in mortar testing is to misuse 2" cube molds. Secondly, such cubes have to be carefully tested in the lab to achieve consistent results. Actually if you achieved 1400 psi on a Type S mortar from sampling in the field and testing in the lab, that's not so bad.
The strength of the final mortar is strongly dependent on the type of materials and the ratio of the components, and testing is required to determine the correct proportions for each application. ASTM C109 describes the methodology for testing the compression strength of mortars using cubes of material that are 2 inches on a side.
