Strain Hardening Can Reduce The Ductility Of Steel Reinforcement

In a stress-strain curve there are various regions and limits like you might have heard about elastic limit and yielding point etc. However in this post we will not talk about all of these points and will only discuss about a phenomenon named “Strain Hardening”.This topic is very important for civil engineers and structural engineers, as the reinforcing steel bars go through this phase…

Marshall Stability Test ASTM D6927

Marshall Stability and Flow Test is basically one portion of the Marshall Mix Design process beside Void ratios and Density calculations as other processes. Marshall Stability Test gives an idea about the sustainability and strength of the asphalt mix of various proportions under the dynamic loading of the traffic. As per the standard procedure for the Marshall Stability test, the sample is first…

Determination of field density of soil by Sand Replacement Method

Sand replacement test method is used to determine the field density or in-place density of earth embankments, road fills, sub-grade, sub-base or any of compacted material. This method serves as base upon which one can accept the density of a compacted material to a specified magnitude or to a percentage of maximum unit dry density determined as proctor. As we know that moisture content of the soil…

Permeability of Granular Soil using constant Head Permeameter

Similar to the constant head permeameter, there is one more test called falling head permeameter in which fall of head is related to the permeability of the soil sample, Before going to the detail of what the test is we must understand what is permeability? So by general or lay man terms; permeability may be defined as; Ability of material to allow water to pass through itSoil in…
