Mortar composition analysis

There are many forms of analysis for testing the composition of the mortar to a formula based on the old plaster. The two most commonly used methods of analysis samples of mortar acid digestion plaster and Test ASTM c1324 test for mortar to cure. As with any individual analytical method, both methods have their limitations and disadvantages.

All forms of the composition of the test mortar requires an understanding of the use in the cement masonry. This is the largest analysis c1324 restrictions mortar. If the results are interpreted with the understanding of the wall someone experience, the accuracy of the results is reduced, and in the best conditions but it is limited.

Analysis of digestion mortar acid can determine the amount of cementitious material, but not its extent.
Since the type of mortar can be based on the product or collapsing pressure, but not as much as compressive strength can be adjusted by adding more or less sand in the mixture or other mixtures such as fibers or hairs, can not determine the composition of formula mortars resistance to the only test compression.

Because of these problems, it was difficult to get an accurate analysis of the composition of the mortar anyway. However, in each of these test methods are no details of the mortar that can not be collected and used to determine the composition of the mortar.

There are a number of scientific or mathematical composition is not used for testing this method with few exceptions approximations.

This method of sample analysis to determine their composition mortar combines several of these tests and collects more results data for use with mathematical calculation of his compositions and the ratio of the proportion of binder.

During the testing, there are a variety of visual inspection and analysis of the expansion or microscopic analysis of samples of mortar. The samples were crushed to determine the compressive strength of mortar and weighed to determine the initial reference point. Then samples were tested by methods acids in the intestinal system. Then, the sample should be dried and re-weighed to determine the amount of weight loss, which occurs when the acid digestion of the sample mortar. At this stage, the sand is analyzed, and the determined particle size gradation. Then, amounts of weight loss are determined.

With all these details of mortar and running, you can use the specific weight of binding materials specified weight to calculate the range of possible mortar probability formula for the composition of the sample. Then, using the pressure of crushing and well-known compositions, you can limit the possible match
