Concrete 101 Concretebc This course presents an introduction to the properties of concrete as needed in concrete construction, including strength and durability. Concrete is generally used in two types of construction, i.e. plain concrete construction and reinforced concrete construction. in pcc, it is poured and casted without use of any reinforcement.
08 Concrete Mix Design Pdf Construction Aggregate Concrete As a beginner, understanding the versatility and benefits of concrete is crucial. this guide will not only help you grasp the basics but also navigate the complexities of concrete, including the importance of a reliable cement estimator. Modern concrete consists primarily of four components: portland cement, sand, gravel and water. a common misconception with concrete is that it dries and gets hard. actually, the hydraulic cement reacts with the water in a chemical process called hydration. Learn what concrete is, how it is made, and what types and strengths are available. find out how to order, calculate, and place concrete for your project with american concrete. This course presents an introduction to the properties of concrete as needed in concrete construction, including strength and durability. students receive a copy of design and control of concrete mixtures (9th edition), relevant industry handouts, as well as copies of each presentation.

This course presents an introduction to the properties of concrete as needed in concrete construction, including strength and durability. students receive a copy of design and control of concrete mixtures (9th edition), relevant industry handouts, as well as copies of each presentation. In its simplest form, concrete is a mixture of paste and aggregates. the paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. through a chemical reaction called hydration, the paste hardens and gains strength to form the rock like mass known as concrete. Concrete is temperature sensitive; it sets quickly in hot weather and slowly in cold weather. the addition of admixtures is often used to slow the set time (retarder) during hot weather and to speed up the set time (accelerators) in cold weather. The basic ingredients of concrete are water, cement (typically portland cement), and aggregate (such as gravel, crushed stone, and sand). when the cement and water mix, a chemical reaction called hydration occurs. this binds the other ingredients together and forms a solid material. In this course you will learn more about the basics of concrete technology to give greater understanding of what makes up concrete and the concrete industry as a whole.
