[Chat Online]The required properties of the lightweight concrete will have a bearing on the best type of lightweight aggregate to use If little structural requirement, but high thermal insulation properties, are needed then a light, weak aggregate can be used This will result in relatively low strength concrete
[Chat Online]So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE On the flip side it is not uncommon to see a 1/4" x .

[Chat Online]What is the R-value for earth, dirt, soil, backfill, or earth berms? How about the R-value of gravel & sand? Reader question: Sir: Does InspectApedia have an R-value for earth when used as a berm on an exterior concrete house wall?
[Chat Online]Are you having issues with low Sand Equivalents? One way to combat a high #200s count is by adding larger rock to the product The Sand Equivalent test is a comparison of the volume of silty clays to the volume of sand in your sample
[Chat Online]52 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate 53 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement

[Chat Online]2009-06-30· If we see the sand equivalent formula, which is 100*sand reading/ clay reading, the higher the sand reading during testing means it gives higher sand equivalent value, and that means there are less clayey materials Either clay content should be calculated as 100-sand equivalent value to set minimum requirement as above or if we use sand equivalent, what the Spe'c should set is a maximum .
