Recognize Different Types & Functions of Concrete

Concrete is one part of home construction. Concrete is formed from a mixture of cement, water, fine aggregates such as sand, and coarse aggregates such as splits. Concrete elements are strong and can withstand high temperatures. Maintenance is easy. Therefore, many home contractors use concrete when building houses. However, there are still many who do not understand well the various types and functions of concrete. This certainly affects the resilience of building and house structures.

Density of Concrete Structures

Concrete structures must meet standards so that the building is more durable and safer. Standardization is related to the density of the structure and the density of the structure is determined by the mixture of materials used. For each building area, this size varies depending on its function. Here are some types and functions of concrete based on the size of the mixture used.

Concrete K-325

The K-235 concrete type is commonly used for the ground floor of factory buildings. The K-325 concrete mixture is cement as much as 439 kg, sand as much as 670 kg, and gravel / coral as much as 1,006 kg.

Concrete K-300

For the construction of a shop building or a 3-storey to 5-storey house, the type of concrete used is K-300 concrete. The K-300 concrete mixture is cement as much as 413 kg, sand as much as 681 kg, and gravel / coral as much as 1,021 kg.

Concrete K-250

The K-250 type of concrete can be used for the construction of two-story buildings or houses with standard concepts. To make K-250 concrete, the mixture is as much as 384 kg of cement, 692 kg of sand, and as much as 1,039 kg of gravel / coral.

Concrete K-225

Construction of a 2-storey building, either a shop or a residential house, can also use K-225 concrete. This type of concrete is a mixture of cement as much as 375 kg, sand as much as 698 kg, and gravel / coral as much as 1,047 kg.

Concrete K-175

Concrete K-175 can be used for light building construction. The K-175 concrete mixture is cement as much as 326 kg, sand as much as 760 kg, and gravel / coral as much as 1,029 kg.

This size can be adjusted according to the amount of mixture needed. In order to keep the density the same, you must use the same ratio.

Cracks in Concrete

One of the most common problems in buildings is cracks. The causes include inadequate concrete density. Initially, cracks can be fine cracks, and then gradually shrinkage cracks. Fine cracks are often seen when the concrete is wet and the surface dries, but it looks very subtle.

The visible cracks are usually 0.1 mm in size. Elongated shape or like a certain pattern. To identify cracks in concrete, a tool that can be used is a crackmeter. Meanwhile, the crack depth can be checked with the UPV (Ultra Pulse Velocity) Test.

Although cracks do not always compromise the performance of a building’s structure, there are several things that might happen, namely:

Loss of structural integrity and unity. This is especially evident in large types of cracks. May cause leakage. If cracks occur in the walls, water can seep in and cause leaks. Water can also enter the structure and cause corrosion of steel reinforcement. Less aesthetically attractive. A crack in a concrete wall or other part will certainly create an unsightly view.

Cracks in buildings can be minimized by measuring the concrete mixture appropriately according to the provisions. Home contractors who are members of the Cipta Kreasi team really pay attention to things like this. So, you don’t need to worry about the results of the building because it is guaranteed to be durable.
