30-08-2020· CONCRETE MASONRY UNIT GUIDE SPECIFICATION. 2.01.A.7 Unless otherwise specified, concrete masonry units conforming to ASTM C-90 will have a minimum average net compressive strength of 1,900 psi. If stronger units are required, specify strength here.
the units in the axis of unit height and masonry tensile strength for Failure Case 2 with the tensile bond strength between the bedjoint mortar and the unit. 2.3 Test Methods At present, there is no standard DIN, CEN or ISO test method for the determination of masonry tensile strength. The methods used in /5/ are recommended as test methods (cf.
Standard Test Methods for Compressive Strength of Masonry Prisms 1. Scope 1.1 These test methods cover two compression tests of masonry prisms: 1.1.1 Method A−For determining comparative data on the compressive strength of masonry built in the laboratory with either different masonry units or mortar types, or both.
Concrete Masonry Unit Compressive Test. Because the test is performed in place, however, samples will not be disturbed in shipping. The third method involves removing masonry units and samples of the mortar and estimating the compressive strength. The masonry units are tested in accordance with ASTM C 67 to determine compressive strength.
grouted concrete masonry construction. For hollow concrete block construction, 282 average/specified masonry compressive strength data points were computed from the test results of 1376 individual prisms. For grouted block construction, 89 data points from 310 individual prism tests …
The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

1.1 These test methods provide various testing procedures commonly used for evaluating characteristics of concrete masonry units and related concrete units. Methods are provided for sampling, measurement of dimensions, compressive strength, absorption, unit weight (density), moisture content, flexural load, and ballast weight.
Compressive strength tests are used to ensure that concrete masonry units meet the minimum strength requirements of the applicable unit specification (see ref. 11). The unit compressive strength results may also be used to verify compliance with the specified compressive strength of masonry, f' m, when using the unit strength method (ref. 4, Article 1.4 B.2.b).
