The effect of size on the compressive strength of concrete is well documented in the literature. In a seminal study, Price [27] examined the compressive strength of concrete under different curing conditions and showed that larger diameter test cylinders have a lower compressive strength compared to smaller diameter test cylinders.
Flow of the mortar was then measured from the diameter of the mortar. 2.2.2. Compressive strength. The mortar was casted into a 5x5x5 cm 3 cube mold and cured in saturated lime water for 3 7 and 28 days at 23 ± 2 °C according to ASTM C109 [13]. The compressive strength was tested by using Technotest compression machines. 2.2.3.

The direct compression test is a traditional method used to evaluate the compressive strength of concrete and mortar, and the test is conducted on cylinders or cube specimens. . The compressive strength of three cement mortar types with different w/c ratios of 0.4, 0.5, and 0.6 was evaluated at the specimen ages of 1, 3, 7, 14, 21, 28, and 56 .
The document is a laboratory report summarizing a test to determine the compressive strength of cement mortar. It includes sections on introduction, materials, test procedure, calculations, results, discussion and conclusions. The test aimed to determine the compressive strength of mortar mixtures with a cement to sand ratio of 1:2.75 and water to cement ratio of 0.485. . This test method covers determination of the compressive strength of hydraulic cement mortar using 50-mm (or 2-in.) cube specimens (see Note 1). Note 1-ASTM C349 provides an alternative procedure for this determination (not to be used for acceptance tests). This test method covers the application of the test using either inch-pound or SI units.Iraq Kurdistan region University of Duhok College of engineering civil engineering Department First stage 2016-2017 Concrete technology Compressive Strength of Hydraulic Cement Mortar Prepared by: Karwan Majeed Group name: A3 NO.

how to calculate mortar
In this section, using the information obtained from performing a compression test on brick masonry wallettes, the relationship between the modulus of elasticity and the compressive strength for the scales of 1:6, 1:4, 1:2 and 1:1 in two RILEM and BS methods as well as samples with two types of mortar, i.e. gypsum mortar and cement mortar, are .
Compressive strength increases as the proportion of the mill scale increase from 0 % to 8 %. The increase in compressive strength is 13.8 % when the mill scale is added at a rate of 8 %, compared to the sample without the mill scale. The increment in compressive strength results from cement paste leaking between the scales' irregular structure.
