The micro-Deval test has good multi-laboratory precision and is a suitable replacement for the sulphate soundness test for fine aggregate. A micro-Deval ... Rogers,C. - 《Geological Society London Engineering Geology Special Publications》 被引量: 29发表: 1998年 Evaluation of Usability for Sub-...
They also suggest that the EN test (Annex B) is unsuitable for fine aggregates. The loss in mass for coarse aggregates tested with magnesium sulphate increases as the fraction size is reduced.doi:10.1016/j.conbuildmat.2012.11.047Ioannis Ioannou...
We say an Account object is an aggregate: its part is the object referenced through the field hist. Part ob- jects are also known as representation objects. We qualify 1The restrictions on o.inv in the preconditions of pack and unpack are not necessary for soundness, but omitting them ...
Then the aggregate damage is assessed by mass loss using a 1.25-mm sieve for coarse aggregates and a 75-渭m sieve for fine aggregates (=-=Lang et al. 2006-=-). 57Figure 25: A Micro-Deval test machine (Inopave 2003). Unlike the LA Abrasion test, this test method is unique in ...
As area and length of main channel in catchments increase, the weight loss difference (from freezing-thawing and sodium sulfate soundness) between fine and coarse aggregates decreases. Indeed, the effect of particle size in the intensity of weight loss reduces with increase in area and length ...
