1. Introduction. Generally, concrete containing around 65–85% of its volume by aggregate. Meaningful that the properties of concrete are mainly dependent on the quality and type of aggregate [1].It is completely known that aggregate is an inactive material, but it is actually inactive due to its physical and limited chemical properties that …
A review on self-curing concrete
The aggregate is a mixture of natural coarse and fine materials. The aggregates are mainly responsible for 70% of the strength gained by concrete. Natural aggregates are obtained from weathering action of rocks and artificial aggregates are obtained from crushing. Aggregates are classified as fine and coarse aggregates, fine …

Buildings | Special Issue : Aggregate Concrete Materials in
Special Issue Information. Dear Colleagues, Aggregate concrete plays a very important role in both underground engineering support and ground building structures. Aggregate concrete is one of the most important civil engineering materials. It is made up of cementitious materials, aggregates, water, and admixtures in a certain proportion.
Pathways towards sustainable concrete
Actually, it is estimated that concrete production is responsible for 9% of total greenhouse gas emissions [23], of which 7–8% from only cement plants [24].In other words, if the concrete industry was a country, it would be the third largest CO 2 emitter in the world with up to 2.8 Gt per year, surpassed only by China (10.18 Gt) and the United States …

Concrete is 'a composite material consisting of a medium of binding in which fragments or particles of aggregates are embedded' within the binder. Thus, the concrete's definition can be simply interpreted as [1]. (1-1) Concrete = filler + binder. In general, concrete is the main building material utilised worldwide.
