Quantity analysis for Materials In 1 cu.m Cement Concrete

Quantity analysis for Materials In 1 cu.m Cement Concrete

Concrete is basically a heterogeneous mixture, which consists of cement, sand, stone aggregates and water. For a big project, where the higher grade of concrete is used, mix design is must to determine the quantities of the materials required to maintain the grade. But when a lesser grade of concrete is used, quantity analysis for Cement, Sand And Aggregate is done by some basic calculation.

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.


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, …

What is Water Cement Ratio – Guide & Calculation

Have you been told, “Add some water, the concrete looks very hard”? Is that right? Adding more water at the site level to increase the concrete workability?? Absolutely Not… What is Water-Cement Ratio? Water Cement Ratio means the ratio between the weight of water to the weight of cement used in the concrete mix. Normally water-cement …

Introduction To Concrete Technology

Background Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water. Although people commonly use the word “cement” as a synonym for concrete, the terms in fact denote different substances: cement, which encompasses a wide …
