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...
However the native soil from the landfill is mostly peat, and I was thinking maybe we could replace the native soil with mixed clay liner, but when I compacted and did a permeability test for the peat itself it shows 10-9 m/s on coefficient permeability, and on EPA it said that "A recompacted...
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...
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...
So I'm going to answer my own question since I already discover some of textbooks that has Rowe Cell in it, just to help if anyone in the future need it.
K.H. Head Effective Stress Tests, Volume 3, Manual of Soil Laboratory Testing
K.H. Head has really clear prodecure and what to do with Rowe...
Hello everyone,
I wonder if any of you could give me some references of Rowe Cell Test textbooks or journals.
I find it difficult to find the literature or the procedure about how to use it.
Thank you so much!
Hi GeoPaveTraffic & Ron
I was told to try to use Rowe Cell. It just my problem right now is how do we know if our specimens are fully saturated or not. We could do triaxial test to make the sample saturated using Triaxial CD right? But the sample size for the triaxial test is different for the...
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...
@jmcc3265 I need the permeability value for landfill design. I tested few samples mix between clay to get the lowest coefficient value, then I came across that there are some different formula to determined the k value.
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.
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...
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...
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...
