Concrete is probably the most important building material today and is used as an alternative for brick/wood since the Roman & Egyptian times.
It is composed of cement,stone[gravel], sand and water which is a key ingredient that hardens the concrete. When reinforced with steel bars it is even more useful.
Concrete is made up of water, sand, cement and ballast. The process through which concrete is made is known as hydration which allows it to harden.
Concrete is made from cement and water. It is a mixture that includes the elements: Ca, Si, Al, O, S, Fe.
The three essential substances are cement - usually Portland Cement, water and aggregates - sand can be part of the aggregate
The two elements present in largest atomic percentages in both glass and concrete are silicon and oxygen.
The trace elements in concrete are,CementFine aggregateCoarse aggregateWaterAdmixtures.
No. Concrete is a mixture of cement and other elements. Reinforced concrete often includes iron or steel beams in it to make it stronger.
No, elements make up minerals.
The elements that make up honey are honey
The two elements present in largest atomic percentages in both glass and concrete are silicon and oxygen.
Common glass is made from sand, SiO2, Na2O and CaO. Concrete is a mixture of rocks (aggregate), sand, and water.
