Definition of aggregates Desirable properties of

Aggregates. Aggregates are the fraction of rock which are inert or non-reactive. These are obtained from rocks by means of crushing. Main constituents of the wearing surface are bitumen and aggregates. Mostly 90 % of the road consists of aggregates. There are two problems to use non-inert materials. Cost will increase.

Desirable Properties of Road Aggregates Civil Engineering

Aggregates form the major portion of the pavement structure. Bear stresses occurring on the roads and have to resist wear due to abrasive action of traffic. Aggregates are also used in flexible as well as in rigid pavements. Therefore, the properties of aggregates are of considerable importance to highway. The aggregates to be used in road construction, particularly

Engineering Properties of Geopolymer Aggregate Concrete

Nov 11, 2018· This paper reports a novel methodology to manufacture geopolymer coarse aggregate (GPA) using low calcium fly ash. The developed methodology is outlined together with a systematic experimental study undertaken to examine a viable manufacturing process for GPA production and the consideration of key mechanical properties and durability characteristics of GPA concrete up to 90 days.
