Concrete may be made with beach sand and shells as aggregate if the materials are clean and correctly graded, although it may not be cost effective. Because shells are often flat and sharp-edged, they produce less workable concrete than more regularly used gravel or crushed stone. Concrete made with shell is also more likely to have air pockets inside it which may cause problems such as cracking in humid climates.
Beach sand is a fine powder with a high water content (75 percent or more) that can be used as an additive for other materials to make them lighter or stronger. It is most commonly used as an additive to make road surfaces more resilient or to provide small amounts of soil for growing plants. Beach sand is a common ingredient in playgrounds and sports fields because it helps those items look new longer without needing to be resealed or repainted.
Beach sand is used in various ways when making concrete. The type of sand used affects how much weight the concrete will hold. Coarser sands allow for greater volume reductions during processing, while finer sands result in a concrete with better quality properties. Both types of sand affect the cost of concrete; coarser sands require more careful selection and handling of the material by workers and equipment during production.

Is it possible to manufacture concrete with only sand and cement? No, only sand and cement may be used to build concrete. Concrete isn't called concrete unless it contains aggregates such as gravel and stone. The aggregates contribute to the high strength of the concrete. Without them, the concrete would not be able to support itself.
Concrete that has no aggregate in it is known as "mass-formed" concrete. This type of concrete can be made using recycled materials or pure limestone. However, its strength will be much lower than conventional concrete.
The most common type of concrete that doesn't contain any aggregate is mortar. Mortar is used to join together pieces of brick or stone for a building project. It's made by mixing water with Portland cement and allowing it to set into a hard mass.
Mortar is used instead of rock for your foundation because it's cheaper than using granite or other natural stones. The stone would have to be extremely large to use as an aggregate in concrete.
As far as we know, there is no way to make concrete without adding some form of aggregate to it. This is because concrete needs material to give it strength and hold it together. If it were just sand and cement, the concrete would fall apart long before it reached its maximum strength.
Concrete Mixing Without Sand While sand is the most commonly used aggregate in the production of concrete, it can also be mixed with gravel, crushed stone, or even chunks of existing concrete. The quantity of water you mix in may vary depending on the aggregate material, but it should be between 15 and 20%.
The type of sand you use will determine how much concrete you can make without any further addition of sand. For example, if you were to use silicon oil as a cement mixer, you would need to add more fine sand to get the same result as when using water alone. This is because silicon oil requires more steel fibers to produce the same result as water. Concrete made with oil tends to be more durable than concrete made with water because the fibers keep the particles apart so they don't clump together.
There are two types of sands used in concrete: natural and manufactured. Natural sands include quartz, limestone, oyster shells, and a variety of other materials. These are the cheapest types of sand and also the most abundant. Manufactured sands are silica rocks that have been sorted and cleaned of all other materials, such as iron ore, clay, or silt. They tend to be smaller in size than natural sands but may contain some residual material that could affect certain properties such as color or durability.
Natural sands can be divided up into three main categories based on their particle size: coarse, medium, and fine.
