Test for Setting Times of Concrete Mixture Based on ASTM C403M-16
The penetration resistance test used for the determination of initial and final setting time of concrete mixture in laboratory and project site, and the effects of variables, such as water content; type and amount of cementitious material; or admixtures, upon ...
Bulk Density and Void Percentage Test for Aggregates
The bulk density and void percentage of aggregate can be evaluated using standard test methods of applicable codes such as ASTM C 29/C29M-17a, IS: 2386 (Part 3) – 1963, or BS 812-2:1995. The procedure provided in this article is based ...
What is Proof Stress? Importance and Determination
Proof stress of a material can be defined as the stress at which the material undergoes plastic deformation. Proof stress is determined as the stress corresponding to 0.2% of strain from the stress-strain curve of the given material. This is ...
What are the Bearing Capacity Values of Different Soils?
The capacity of the soil to allow the loads coming from the foundation is called bearing capacity of the soil. The gross pressure at the base of the foundation at which soil fails is called ultimate bearing capacity. By considering ...
Variable Head Permeability Test of Soil- Purpose, and Procedures
Variable head permeability test is one of several techniques by which the permeability of soil is determined. It is used to evaluate the permeability of fairly less previous soil. Permeability is the measure of the ability of soil to allow ...
