Comparative Analysis of Micro-Deval, L.A. Abrasion, and ...

Test results were normalized to facilitate direct comparisons between Micro-Deval, L.A. Abrasion, Sodium Sulfate and Magnesium Sulfate tests. Linear regression of the data points and corresponding confidence intervals were plotted to qualitatively assess agreement or disagreement between test methods. Results of this study indicate that the Micro-Deval test is a suitable replacement for the ...

Sodium sulfate - Wikipedia

Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product. It is mainly used for the manufacture of detergents and in the kraft process of ...

Comparative Analysis of Micro Deva Abrasion and Sulfate

Aggregates that pass the Micro-Deval test will likely also pass the L.A. Abrasion, Sodium Sulfate and Magnesium Sulfate tests; that is, the Micro-Deval test is more “conservative.” 2. Based on the 95% statistical confidence bands, the authors suggest that the greatest likelihood of pass-fail conflicts will occur when the percent loss of a sample is slightly greater than the Micro-Deval ...

Investigation of Testing Methods to Determine Long-Term ...

and sodium sulfate soundness test results are known. Two 3-parameter equations and one 4­ parameter equation are proposed for predicting the outcomes of the Micro-Deval test for each threshold loss limit. These equations could correctly predict all (100%) of the Micro-Deval outcomes in the 69 sets of tests performed under the Phase I study (using 18% loss limit). The unconfined freeze/thaw ...

As shown in Fig. 5, the Micro-Deval and sodium sulfate soundness tests had similar passing results with a 93.8% agreement rate. One aggregate (N-6) was considered problematic because sodium sulfate soundness test indicated an acceptably durable aggregate while the Micro-Deval test did not. The linear fit of the data had a slope less than 1 (0.4052) indicating the Micro-Deval test was more ...

This study presents the findings from a research investigation conducted to characterize the toughness/abrasion resistance and soundness of aggregates from 23 sources using the micro-Deval, Los Angeles (LA) abrasion, sodium sulfate soundness, and magnesium sulfate soundness tests. Correlations between the results of micro-Deval test and other tests were explored, and the NCHRP 4

Comparative Analysis of Coarse Surfacing Aggregate

Laboratory tests (Micro-Deval, L.A. Abrasion, and Sodium Sulfate) were conducted on a variety of soil types to examine the repeatability of each test method, and to examine how well the methods correlate with each other in terms of predicting aggregate durability and degradation. Test results were normalized to facilitate direct comparisons between the three methods. Linear regression of the ...

MICRO-DEVAL TESTING OF AGGREGATES IN THE SOUTHEAST

Deval test, in conjunction with the Magnesium Sulfate Soundness test, was recommended in lieu of the L.A. Abrasion and Impact test and other soundness tests. Micro-Deval Test The Micro-Deval test was developed in France during the 1960s and was based on the Deval test developed in the early 1900s (3). The Micro-Deval test provides a measure of abrasion resistance and durability of mineral ...

01/10/2014  The lower portion immersed in the sodium sulfate solution can suffer from chemical sulfate attack, while the upper portion can be vulnerable to physical sulfate attack. High damage due to six months of exposure to physical sulfate attack did not affect both the concrete compressive strength and modulus of elasticity since the damage was only limited to the external surface of the concrete.
