Mortar Testing for Estimating Strength

01/09/1999  A comparison between the compressive strength and rate of hardening of mortar and concrete is presented. Two types of mortar are used: the first is mortar screened from the concrete through a 4.75 mm (No. 4) sieve and the second is mortar proportioned based on the volume ratios of cement, sand, and water in the concrete mix. The relationship between concrete and mortar is the

MASONRY MORTAR TESTING - NCMA

When tested at an aspect ratio of ⅜ :1, tested mortar compressive strength values are routinely 8,000 to 10,000 psi (55.16 to 68.95 MPa). For these reasons as well as others, field mortar compressive strength test results should never be compared to the requirements in ASTM C270 Table 2, which apply to laboratory-prepared mortar only.

MASONRY MORTAR TESTING - NCMA

Compressive Strength Testing of Field-Prepared Mortar. Compressive strength is one of the most commonly tested properties of field mortar. The test, described in ASTM C780, provides an indication of mortar consistency during construction, not as an indication of the compressive strength of the masonry, or even of the mortar in the wall. Compressive strength test results should be compared

How to Estimate Strength of Concrete through Maturity ...

The maturity of concrete is determined by a non-destructive approach, where the compressive strength at early ages is detected to conclude about the maturity. This test is conducted on an in-place real-time concrete mix at the site. The use of a maturity test on concrete at the job site helps to eliminate the need for concrete cylinder breaking tests and hence save and optimize the project ...
