Why ballastless track used in only tunnel and bridges.

 why the Ballastless track or slab track only used in tunnels in bridges? Ballastless track or slab track is only used in tunnels, bridges, and sometimes in railway platforms because slab track systems require stable subsoil basically free of settlement in order to perform adequately. The substructure of the slab track must be down to a depth of 2.5m below the bearing plate by special earthwork treatment that increases the cost and drainage problem is also issue to perform the Ballastless track that's why Ballastless track not used in the open rail track.   

Is there permission for use AAC bricks in school building?

The use of AAC bricks in school buildings will be a good idea to make school buildings more economical in terms of saving time. there are the following advantages of the ACC block. AAC block is eco-friendly. AAC block dead load is less and it reduces the quantity of cement and steel at the time of structural design. More economical than brick if we compare with  bricks although initial cost of AAC block is little bit high. AC block has high thermal and sound insulating properties                                Due to its various advantages, it can be used in the school building to complete building on time and make building more economical.  In India, there is no such case that we can not use it in the school buildings. We obviously can use it for the school building.   

Ballastless Track (BLT) in India | Ballastless track system | Rail Track

Ballastless Track Ballastless track or slab track is a type of track system construct without using ballast. We are using mines waste as railway track ballast having various advantages but at a certain limit. like The ballasted track requires a low investment cost. The ballasted track is usually easy to lay. The ballasted track has good drainage performance.  Good quality track ballast is made of  crushed stone                                  Ballastless Track (BLT) in india Made of concrete and asphalt that are replacing standard ballast track. Due to the use of concrete it becomes very stiff and brittle. to obtained elasticity we generally provide elastic pad below the rail. There are two types of concrete are going to using in Rheda 2000.
