What will happen to the concrete mix if the amount of aggregate used is large?
From a recent science test I completed shows small doses of aggregate seem to strengthen the mixture, but as more is added, it becomes worse than with none at all.
How do you make a concrete mixture?
just get a gravel, sand, and cement and then mix it with a little amount of water.
Is wet concrete heavier then dry concrete?
Concrete is made of a mixture of cement, aggregate (small stones), fine aggregate (sand), water and other chemical additives. When mixed the wet concrete will remain so for Most people assume that set concrete has no water in it, this is not so, as the water content helps bond the aggregates and cement, this process is known as Hydration. Concrete with no water in it would crumble to dust. Adding more water to the mix will make a concrete that is easier to work, while less water will produce a stronger, more durable concrete. After initial setting of the concrete, a slow amount of water loss is expected due to the concrete drying, it can take anything up to a year for water to stop evaporating slowly out of the concrete. So for this reason the answer to your question is yes, dry, set concrete will weigh less than wet concrete, but for anything up to a year it will keep getting lighter, due to waterloss.
How do you make cement or concrete?
cement/ concrete is made with water, cement mixture and sand. After all of this is added to the right amount, you mix, mix, mix!! Then bofore it drys, pour it ontop the location desired
What is a yard of concrete?
Definition of the amount of concrete that (by volume) will fill on cubic yard of space.

How do you make concrete denser?
Use a higher density aggregate, or decrease the amount of air entrainment.
What does aggregating mean?
There are several explanations. In botany it refers to florets collected in a dense cluster, such as in a daisy. In geology it is a mixture of minerals separated by mechanical means. In medical terms it means crowded or massed into a dense cluster.

What is the workability of concrete?
The property of concrete which determines the amount of useful work (like- water content, mix proportion, size of aggregate used and use of admixtures) necessary to produce full compaction is called workability.

What are the major ingredients for concrete and what role do they play?
cement- reacts with water to form "glue" water- reacts with cement, the amount also determines strength aggregate- makes concrete stronger, more durable, and less costly
Why pouring concrete onto a driveway and allowing it to set a chemical change?
allowing concrete to set is a chemical reaction where the Portland cement goes from a liquid slurry between the rocks and sand in the concrete (called aggregate) to a crystalline medium that bonds the aggregate together as an artificial mineral. In addition to radically changing the physical properties of the concrete (from a runny goo to a solid surface) the process also gives off a significant amount of heat and isn't easily reversible.
What are concreate and steel?
Concrete is a mix of cement, water and small stones (called aggregate) that hardens like rock when it sets. Steel is a iron that contains some amount of carbon.

Why GDP equals aggregate expenditure and aggregate income?
GDP would be the amount of gross income a person or company receives. This would be the amount of income minus the amount of expenditure on things like bills.
How much does 6500 psi concrete weigh?
The weight of concrete is determined by its density, which is typically around 150 lbs/ft³. However, the density of concrete can vary depending on the type and amount of aggregate used, as well as the water-to-cement ratio. Additionally, the weight of concrete can also be affected by the compressive strength of the concrete, with higher strength concrete often weighing more than lower strength concrete. Therefore, the weight of 6,500 psi concrete can vary, but it is typically around 150 lbs/ft
