That depends on the mix, there are hundreds of different mixes of concrete. A basic mix of concrete (say a blended RC25 mix) has 1000kg of sand, 1000kg of stone, 150kg of OPC cement, 125kg of GGBS slag, 1.3lt of WRA and 75lt of waters PER CUBIC METER. Regards Colin, a Tarmac concrete batcher.
Ballast, sand and cement (+water).
Concrete block is made from Portland Cement, water, sand and aggregate. The aggregate may be in the form of flyash or cinder from burnt coal.
Aggregate, Ordinary Portland Cement, sand, water
Mineral admixture are those which are mixed with concrete ingredients and spread through out the body of concrete to favourably modify the properties of concrete . the commonly used mineral admixture are1. Fly ash2. Silica fume3. Rice Husk ash4. matakaoline

concrete ingredients are directly feed in to the mixture plant and mixing done by means of machine. And it is pumped by means of concrete pump and placed in the site.
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
The primary ingredients of concrete—cement, water, aggregates, and admixtures—interact to create a durable construction material. Cement binds the ingredients together, water activates the cement, aggregates provide strength and volume, and admixtures enhance specific properties like workability or durability. The combination of these ingredients results in a mixture that hardens over time to form a strong, long-lasting material suitable for various construction applications.
Without aggregates or sand it is not concrete.
