I was wondering if there are any specific guidelines for the preparation of artificial soils in laboratory. In general we tend to add some different soils and make a blend of a new soil with distinct properties but somewhat corresponding to the parent material. Is any research available on the preparation of the same apart from use.
As we know apart from the processes of weathering and transportation respective minerals define the nature and formation of soil. There are some studies regarding the preparation of artificial soils. To what extent that research is advanced I don't know, but I can tell that there has been some study done in this area. This answer may not be meeting what you tried to ask for but what compelled me to write back is the beauty of the concept of artificial soil.
Interesting never thought about making one. The soil making process is a long process and not quite sure if a true soil type that we enjoy can be made artificially woking on parent materials.
@patrik s. michael thanks for ur answer....indeed it is a very novel concept...but needs a proper channelized work
By artificial soils, if you mean controlling the properties of the soil as per our own desired requirements, then blending together soils of different nature is the way out and there are various studies regarding that.
Hello, if artificial soils are intended as the preparation in lab of mixed basic components, some steps should be respected, as multicomponent blend:
- definition of real scale grain size distribution;
- level of compaction and water content to set initial parameters for testing;
- scale laboratory effect to evaluate the amount of mass necessary for the artificial mix;
- in case of excess of coarse material, separate the large diameter classes but take into account for influence of some parameters (mechanical or operational)
- take care of requirements of homogeneity during preparation but in the meantime consider what will happen in reality during operation (dumping, mixing, compaction, long term aging or clogging, etc).
The hydraulic and mechanical properties of soils depend on physical and chemical interaction between particles.
These are only suggestions as each case should fit specific site and design condition for the intended use (drainage, paving, backfilling, subgrade etc) , starting with classical geotechnical testing procedures for sample preparation.
