Lecture On Concrete Aggregates

  • Lecture 4. Aggregates

    Large aggregates are economically advantageous in Portland cement and asphalt concrete, as they have less surface areaand, therefore, require less binder. However, large aggregate mixes, whether asphalt orPortland cement concrete, are harsher and more difficult to work into place.

    Lecture 5. Concrete. 1. Coarse aggregate makes solid and hard mass of concrete with cement and sand. 2. It increases the crushing strength of concrete. 3. It reduces the cost of concrete, since it occupies major volume. Requirements: 1. Coarse aggregate used may be crushed stone, gravel and broken bricks. 2. Crushed stone: It is an excellent

  • Different Types & Sizes of Aggregate for Concrete

    Aug 11, 2018· Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 60 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Aggregate may be natural, manufactured or recycled.

  • Lecture 5. Concrete

    Concrete is a mixture ofcement,water, fineaggregate(sand) and coarse aggregate (gravel or crushed rocks) in which the cement and water have hardened by a chemical reaction hydration to bind the nearly (non reacting) aggregate. Figure 1.Basic ingredients of concrete

  • Concrete Technology, Lectures & Course Notes on Concrete

    In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

  • Aggregates: Physical Properties and Mechanical Properties

    Aggregates generally occupy 65- 80% of a concrete’s volume. Aggregates are inert fillers floating in the cement paste matrix for concretes of low strength. The strength of aggregates do not contribute to the strength of concrete for low strength concrete. The characteristics of aggregates impact performance of fresh and hardened concrete.

    This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to place, work and compact, but can make concrete stronger.

  • Period #14 Notes: BITUMINOUS MATERIALS (I)

    There are two basic classes of bituminous materials: (1) asphalt; and (2) tar. These materials are generally used as water-proofing sealants, and as a binder to hold aggregate together in bituminous pavements. In this set of notes we will discuss the differences between these two bituminous materials, and the sources of these two materials.
