    Sikament LN Problems

    Hello everyone, I'd like to ask you regarding Sikament LN, which known as water reducer and will accelerate the hardening process of the concrete. I'm doing a research where I need to use 2% of Sikament LN to add to the concrete admixture. While making the admixture, I got some problems which...

    Peat soil for landfill

    Is it suitable if we use peat soil as landfill? I run a test of the fully saturated and compacted peat soil's permeability and I got 10^-9 m/s which meet the requirement from the U.S. Environmental Protection Agency (EPA). Is it really safe to use peat instead of clay? If not why? Thank you so...

    Regarding Saturation on Hydraulic Cell Consolidation Test

    So I'm planning to do a saturation on a samples using hydraulic consolidation test (rowe cell) and I'm following the procedures from BS 1377 Part 6 1990, which actually kind of confusing me. They also have this form to be filled when we're doing the saturation test. If any of you happen to know...

    Hydraulic Conductivity Procedure (Falling Head Test) for Compacted Soil

    Hello everyone, I'm doing some test for landfill design for my research. I have some specimens that need to be tested, and all of the specimens are a mixed soil between four type of soils, which are organic/peat soil(in USDA classification it classified as loamy sand), kaolin (USDA classified...

    Hydraulic Conductivity (Coefficient of Permeability) Formulas

    How many formulas that exist to find the hydraulic conductivity value in falling head test? Especially if we do the permeability test on recompacted soil. Thank you.

    Atterberg Limits for Peat or Organic Soils

    Hello. So I'm about to do a several tests for the peat soils and one of them is atterberg limits. So I wondering should we dry the soil overnight in the oven before we do the test or just do the test without drying it? Is there any special treatment or method we should do when we're doing the...

    Clay lining to protect groundwater from leachate

    What kind of clay work the best to protect the groundwater from leachate? I know that we need a hydraulic conductivity less than 10^-9 to do that....but I read somewhere that bentonite and kaolinite don't have a low hydraulic conductivity like what we need to do the lining. I need explanation...

    K Value on Hydrometer Test

    So does anyone have a table about values of K used in the equation for calculating the diameter of particles in hydrometer analysis that has Gs (soil specific gravity) lower than 2. All I can found the table start from 2.45. But my Gs is around 1.8 so I need a table that lower than 2.45 Can...

    Water Content of Kaolinite Clay Exceed 100%. Is That Possible?

    So I tested the water content of kaolinite clay yesterday. The clay we tested was a disturbed clay, so it has been going through a lot of weather changea and other condition. I tested it by following the procedure we usually use at the laboratory and put the clay in the oven for 24 hours in 110...
