The Basic Ingredients of Concrete

The basic ingredients of concrete include sand, natural gravel, crushed stone, and water. Many companies offer recycled concrete made from waste materials from construction, demolition, and excavation, but manufactured concrete is also allowed be tong tuoi . The amount of each depends on the use for the concrete and the desired outcome. For example, if a home is to be used as a playground, it should have the appropriate amount of sand. In some cases, concrete is not the best material for a driveway, because it can become brittle.

A normal mix is composed of a cement-to-sand ratio of approximately 1:24 for ordinary construction. The proportion of each component is finalized in laboratory tests, and is the most common mix. This type of concrete is suitable for buildings that do not require high tensile strength, but are not suitable for use in other structures that require high-strength, stiffness, or flexibility. However, it is important to note that it is not the best material for structures that need to resist vibrations and wind loading.

In order to create a durable concrete, it must contain a variety of fine and coarse aggregates. Fine aggregates are smaller than 0.25 inches and have a weight of 6.5 to 38 mm. Coarse aggregates, on the other hand, are larger and range from 0.5 to 1.5 inches in size. In order to make a good quality concrete, the aggregates should be free of soft particles and vegetable matter. Organic soil compounds can cause chemical reactions, which can significantly reduce the strength of concrete.

Depending on the intended use of the concrete, there are two types of mix. Nominal mixes are used for ordinary construction, and most use a 1:24 ratio of cement to sand. Whether a building is a bridge, or a house needs to have high strength, a nominal mix will do the job. A design mix is based on finalized proportions from lab tests, and depends on the compressive strength of the structure. During its curing process, concrete is mixed with different types of machines. A mixer is a good choice for producing fresh concrete.

In general, normal strength concrete is composed of sand, gravel, or crushed stone. Generally, this type of concrete is used for pavements and other structures that do not require high tensile strength. In addition, it is not suitable for buildings that are exposed to vibrations or wind. For this reason, it is a good idea to consult a certified engineer before choosing the type of concrete for a particular structure. The optimum ratio is between a normal and a large-size aggregate.

Normal strength concrete is made by mixing sand, cement, and water. This type is often used for larger-scale construction projects and requires less effort than dry-mix concrete. Although it has similar properties to dry-mix, it is not mixed in any way. Typically, dry-mix is less expensive than ready-mix. It is also easier to find, but may be hard to locate. It should be used within a few hours.
