Who was the inventor of consolidation test?
The Classical Method of soil testing for consolidation was developed by Karl Terzaghi. Consolidation occurs when a pressure is applied to a soil whereby water is squeezed out but the space is not replaced by air.
What is a soil test for building construction?
There are a large number of soil tests related to construction:Particle Size Distribution test - finds the relative proportions of differing grain sizes within a soilAtterberg Limit test - used to establish the plasticity class of the soilCompaction test - used to find the optimum moisture content to achieve a maximum densityConsolidation / Oedometer testing - used to establish the settlement potential of a fine grained soil.Direct Shear test - used to measure the peak (and potentially residual) shear strengths of a soil. When tested at varying confining loads can be used to find the shear strength parameters Phi' and c'*Triaxial testing - used to find the elastic properties of the soil (Young's Modulus and Poisson's Ratio) along with the shear strength. These may be either drained or undrained tests.Constant and falling head permeability tests - used to establish the hydraulic conductivity / coefficient of permeability for coarse and fine grained soils respectively.*Note in the UK c' is assumed to be zero for design purposes, in other countries small non zero c' may be used.
What is the procedure for pumping-out-test for soil permeability in soil mechanics?
The pumping out test can be used to measure the average k value of a stratum of soil below the water table and is effective up to depths of about 45m . A casting of about 400mm diameter are put down on radial lines from the casting, and both the casting and the observation wells are perforated to allow easy entrance of water. the test consist of pumping water out from the central casting at a measured rate (q), and observing the resulting draw down in ground water level by means of the observation wells.

What is the CBR value required for good soil?
A CBR value of 10-15% is generally considered good for soil in terms of its strength and bearing capacity. Higher CBR values indicate better soil strength and load-bearing capacity, which is important for road construction and other engineering purposes.
What is the link between CBR and bearing capacity if you get figures in CBR how can you link them to the bearing capacity in kPa?
The link between CBR and bearing capacity if you get figures in CBR how can you link them to the bearing capacity in kPa, this is the link in soil testing.

What is the minimum CBR value required for a MAAS instalation on undisterbed soil?

What is the minimum CBR value required for a MAAS installation on undisturbed soil?
7
What does mean by CBR in sub base compaction test?
CBR stands for California Bearing Ratio, which is a test used to evaluate the strength of subgrade soil and sub-base materials in road construction. The test measures the resistance of a material to penetration by a standard-sized plunger, comparing it to the resistance of a standard crushed stone material. A higher CBR value indicates better load-bearing capacity, which is crucial for ensuring the durability and stability of the pavement structure. It is commonly used in the design of flexible pavements and in assessing the quality of sub-base materials.
If the mat is placed over a soil base the California Bearing Ratio CBR value must be at least?
10
What is the plural of soil test?
The plural of soil test is soil tests. As in "soil tests were carried out at the incident site".
If the MAAS is going to be installed on undisturbed soil that is less then 7 CBR what anchoring method is recommended?
Dead-man and anchor chain
Types of soil test?
macro and micro mutrients test in soil through FTIR
What does CBR stand for in Honda CBR?
CBR stands for "City Bike Racer" in Honda CBR motorcycles, a line of sport bikes manufactured by Honda.
