Cement precast concrete block forms

Types of cement precast concrete block forms

There are various types of cement precast concrete block forms, which can be grouped according to their design, usage, or other features. According to their design and functionality, the following ten types of block forms are popular.

• Open-Top Forms: This kind of formwork is open at the top. It includes horizontal platforms and vertical sidewalls, which enclose the liquid concrete. When the concrete solidifies and takes the shape of the form, the sides of the forms can be stripped off, leaving the cast block.
• Open-Top with Partitions: Such forms have partitions within them. They enable multiple precast blocks with different configurations to be cast simultaneously in a single form.
• Open-Top with Embedment: This form type with integral anchors or inserts enables secure connections or attachments to be made to the precast component.
• Closed Forms: They include closed rectangular boxes with open bottoms, which enclose the liquid concrete from all sides and are available for making solid blocks. In general, closed forms are usually more suitable for casting solid, homogeneous precast blocks.
• Closed with Manufactured Cores: This type of closed form has built-in cores or voids, which help for the configurations of the precast blocks.
• Closed with Removable Cores: Such closed forms use removable cores, which enable the production of specific internal configurations or cavities in the precast blocks.
• Hinged Forms: This kind of form has hinged sections that enable the forms to be opened for block removal. Moreover, they are often used for casting repetitive block configurations.
• Flexible Forms: Made of materials such as plywood or rubber, they are suitable for casting blocks with non-standard shapes or configurations.
• Combination Forms: Also known as hybrid forms, they are made by combining two or more types of forms mentioned above to meet specific requirements for casting operations.

Specifications and Maintenance

Specifications

• Materials used: Cement precast concrete block forms are usually made from strong materials.
• Size: The average size of the cement precast concrete block forms is 4 x 8 x 16 inches. However, these forms can also be made.
• Mode of operation: Its mode of operation can be manual, semi-automatic, or fully automatic.
• Pumpable or pourable design: Pumpable mixes are more fluid and easy to cast, but less so in the case of pourable designs.
• Finishes and features: The appearance and surface of cement precast concrete block forms can be changed by using different techniques to get a smooth or textured finish.
• Strength and durability: They are made of precast concrete block forms that can resist pressure, cracking, and wear out for many years.
• Joint system: Cement precast concrete block forms have keyways, grooves, or mask joint systems that help links and seal.

Maintenance

• Care:

  Strictly follow manufacturer's care and cleaning instructions. This will help maintain its integrity and finish, and the maintenance cost will be reduced.

• Clean:

  After use, clean up any debris, dirt, or residue quickly. This will prevent build-up and ensure a clean surface for the next use.

• Wash:

  Sometimes, it's necessary to wash the form with mild detergent and water. Be careful not to damage the surface.

• Storage:

  Store forms in a dry, covered area away from extreme temperatures. This will prevent warping, cracking, or damage. Keeping them off the ground can avoid moisture transfer and damage.

Scenarios of cement precast concrete block forms

Cement precast concrete block forms are very useful during construction. They can be used to make concrete blocks for walls or to create blocks with cut-outs and features for utilities infrastructure.

One of the most common uses of cement precast concrete block forms is creating concrete blocks or slabs for foundations, load-bearing walls, and non-structural walls. Using cement precast, one can create a uniform concrete block that will have the strength to support heavy loads. Besides, using cement precast concrete block forms can help companies save time and money by allowing them to make multiple products quickly and easily.

Cement precast concrete block forms with cut-outs and features can make interlocking blocks of variable shapes that can be used for water management systems like drainage, sewage, or sanitarywater pipelines, manholes, inspection chambers, and canal and ditch liners. The customized features of the blocks made with the cement precast concrete block form can cater to specific functional requirements like flow regulation and access for maintenance. Because the blocks are often heavy-duty, they can ensure durability and performance.
