WHAT ARE THE PROPERTIES OF AGGREGATES FOR CONCRETE

Engineering Properties of Aggregates. Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow. Composition; Size Shape
