Precast structures are pre-made concrete elements used in construction.
Precast segments are manufactured off-site and transported to the construction site for assembly.
They are commonly used in bridge construction, tunnels, and other large-scale infrastructure projects.
Precast segments can be designed to fit specific project requirements, reducing construction time and costs.
They offer high durability and strength, and...
Segment casting can be done using various methods depending on the material and application.
One method is sand casting, where a mold is created using sand and the molten metal is poured into it.
Another method is investment casting, where a wax pattern is created and coated with ceramic before the metal is poured.
Die casting is a method where molten metal is forced into a mold under high pressure.
Continuous casting is u...
Grade of concrete refers to its strength and durability.
Grade of concrete is denoted by a number followed by 'M' which stands for mix.
The number represents the compressive strength of concrete in megapascals (MPa).
Common grades of concrete include M10, M20, M30, etc.
Higher grade concrete has higher strength and durability.
For example, M20 grade concrete has a compressive strength of 20 MPa.
Design mix of concrete refers to the proportion of materials used in making concrete.
Design mix is determined based on the strength and durability requirements of the concrete.
The mix includes cement, water, aggregates (sand, gravel, crushed stone), and sometimes admixtures.
The proportions of each material are specified in terms of weight or volume.
For example, a common mix for general use is 1:2:3 (cement:sand:gravel)...
Segment casting is a method of casting concrete segments for tunnel lining.
Segments are cast in a factory and transported to the tunnel site.
Segments are then assembled to form a complete tunnel lining.
This method is commonly used in tunnel construction projects.
It allows for faster construction and better quality control.
Examples include the Channel Tunnel and the SMART Tunnel in Malaysia.
