Concrete Slump Test Procedure, Applications & Types of Slump

A slump test is a method used to determine the consistency of concrete. The consistency, or stiffness, indicates how much water has been used in the mix. The stiffness of the concrete mix should be matched to the requirements for the finished product quality.

Properties of Concrete

Properties of Concrete Concrete is an artificial conglomerate stone made essentially of Portland cement, water, and aggregates. Properties of Concrete While cement in one form or another has been around for centuries, the type we use was invented in 1824 in Britain. It was named Portland cement because it looked like the

Fiber Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibers. Fiber reinforced concrete are of different types and properties with many advantages.

Introduction To Concrete

Concrete is a very strong and versatile mouldable construction material. It consists of cement, sand and aggregate (e.g., gravel or crushed rock) mixed with water. The cement and water form a paste or gel which coats the sand and aggregate. When the cement has chemically reacted with the water (hydrated), it hardens and binds the whole mix ...

Concrete | Introduction to Concrete

Jun 29, 2012 · What is Concrete? The word “concrete” has its origin from the Latin word “concretus”, which means to grow together. It is a rocklike material that is produced by mixing fine and course aggregates. British engineer John Smeaton made the first modern concrete in the year 1756. He added pebbles as the course aggregate with brick powder ...

Concrete is prepared by mixing cement, water, and aggregate together to make a workable paste. It is molded or placed as desired, consolidated, and then left to harden. Concrete does not need to dry out in order to harden as commonly thought. The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden).
