the general sense of friction can be used for answering this
since angular particles have more friction in between them as compared to regular stone particles they hold together better

Is aggregate the same thing as concrete?
Aggregate is the gravel or stone in the concrete. It is what gives concrete it's strength. Think of the aggregate as the bricks of a wall and the concrete and sand as the mortar.
What us the density of 2A stone aggregate?
If by aggregate you mean the 'rock' mixed in to make concrete, then the density is usually about 2.7 g/cm3 .
Why does concrete sparkle?
Quartz is often found in the stone used as the aggregate. This adds a 'sparkly' element.
What does concrete?
Concrete is a well proportioned mixture of cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. The more inclusive answer is that concrete is a matrix of stone/sand aggregate adhered into a mass with a binding agent like Portland Cement or hot asphalt oil. This can refer to a person: He was as solid as concrete and would not move off his position.
What is a nonmetallic mineral resource that is made up of crushed stone or gravel and is used in making concrete?
aggregate!
What are the primary ingredients of concrete?

What is a use can basalt be used for?
Basalt can be crushed into crushed stone (aggregate), and used as a material in making concrete or asphalt paving.
What does concreteness mean?

What is the most important ingredient of concrete?

How is concrete made?

How do you know if your stairs are cement or concrete?
um, they'll be hard. duh. ----------------- concrete is made of cement, sand and aggregate (stone, gravel, etc) so its a redundant question. Cement by itself is not very strong, its is a binder used to make concrete. In some cases sand is also the aggregate (QuickCrete is one product name)
Is concrete an example of covalent bond?
Yes, concrete is an example of a covalent bond.Concrete is a composite construction material composed primarily of aggregate, cement, and water.When concrete is made, in its process of setting, the cement undergoes hydration as it reacts with water to bind the matrix of sand and stone aggregate resulting in a silicate product, known as tobermorite.The tobermorite, thus formed in strong crystals adheres the sand and aggregate by means of silicon-oxygen covalent bonds.
