Behavior of Cement Concrete Using Recycled Concrete Aggregates

The requirement of concrete aggregate in India is large. Corresponding to the current annual production of cement of 300 million tons, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 metric tons per year is a safe estimate. There is difficulty in obtaining natural aggregates within economic distances. Search for alternate sources of aggregates thus assumes importance. One such alternative is recycled concrete aggregate derived from construction and demolition wastes, which allow conservation of natural resources and land.

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 …

Flash Point and Fire Point Tests of Bitumen

Flash Point and Fire Point Tests of Bitumen

Flash point of bitumen is the temperature at which, its vapour will ignite temporarily during heating when a small flame is brought into contact with the vapour. The knowledge of this point is of interest mainly to the user, since the bitumen must not be heated to this point. The flash point tells the critical temperature at and above which suitable precautions are required to be taken to eliminate the danger of fire during heating. This temperature, however, is well below that at which the bitumen will burn. The latter temperature is called the fire point.

What Is Repair And Rehabilitation Of Structure

Introduction: Repair and Rehabilitation is the process of improving an existing structure for new conditions of use. It aims at restoring the structure to its original service level it once had and has now lost. In some cases, this consists of giving the structure the service level which was intended, but could not be attained …

What is Bacterial Concrete or Self-Healing Concrete?

Bacterial Concrete or Self-Healing Concrete (SHC) is a modern approach in civil engineering for repair purpose. As the name suggests, this type of concrete can heal itself when cracks appear after curing and hardening. In this article, I will discuss it’s brief history, mechanism, production, advantages, disadvantages and some other aspects. Before we get started, …
