Aggregates Lecture 1 Pdf Construction Aggregate Concrete In the “aggregates matter” activity, students can get messy to learn about aggregates. they can make three different concrete samples, with differing amounts of fine and coarse aggregate, and then test and observe how each sample stands up to an impact by dropping a rock on their concrete sample. This lecture introduces aggregates, the largest volume component of concrete, and explains how mineralogy, shape, texture, and moisture conditions influence concrete performance. The aggregates used in bituminous pavements should have less affinity with water when com pared with bituminous materials, otherwise the bituminous coating on the aggregate will be stripped off in presence of water. Crushed stone, sand, and gravel are the three kinds of rock fragments that are called aggregates. consider: at the current rate of usage, every american will need 1.37 million pounds of aggregates in his or her lifetime.

Durability of concrete factors affecting durability permeability cracking reinforcement corrosion; carbonation, chloride penetration, sulphate attack, acid attack, fire resistance; frost damage, alkali silica reaction, concrete in sea water non destructive testing of concrete surface hardness test ultrasonic pulse velocity method penetr. Natural aggregates – native deposits with no change in their natural state other than washing, crushing and grading. (sand, gravel, crush stone) b. artificial aggregates – obtained either by product or by a special manufacturing process such as heating. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material. the expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product. Understanding the characteristics and testing procedures for aggregates is essential for civil engineers to design and ensure durable and cost efective structures.
