classification of rocks for engineering purposes

How To Classify Rocks For Engineering Purpose

Have you ever thought about how to classify rocks for engineering purposes?? Aggregates are one of the most important materials in civil engineering. Basically, Construction aggregate, or simply “aggregate”, is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. They give …

Different Types of Failure of Foundation

Introduction Types of foundation failure depend on the load it is subjected to. A foundation can fail in three different ways under loads. They are as follows: Punching shear failure of the foundation One-way shear failure of the foundation Flexure failure of the foundation. The above three modes of failure should be checked during the design …

What is Geo Synthetics – Definition, Application, Limitation

Introduction Generally, geosynthetic refers to a product that is made from polymeric material and is applied as a key component in a structure or system to achieve engineering purposes. The prefix “geo” suggests whose application has to do with soil, rock, and/or earth. There are some basic functions of geosynthetics namely separation, reinforcement, filtration, drainage, …

Determination of field density of soil by Sand Replacement Method (IS 2720-28)

  Introduction 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 the 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 …

Classification of Soil for Engineering Purpose

Introduction:- A number of systems of classification have been evolved for categorizing various types of soil. Some of these have been developed specifically in connection with ascertaining the suitability of the soil for use in particular soil engineering projects. Some are rather preliminary in character while a few are relatively more exhaustive, although some degree …
