Why shrinkage is more in Singly Reinforced section as compare to doubly Reinforced Section in RCC ?
MohamedAquib
Singly reinforced beam: The beam that is longitudinally reinforced only in tension zone is called a singly reinforced beam. In this beams, bending moment and tension is carried by reinforced bar and compression by concrete. It is not possible to provide a singly reinforced beam. Because we need to pRead more
Singly reinforced beam:
The beam that is longitudinally reinforced only in tension zone is called a singly reinforced beam. In this beams, bending moment and tension is carried by reinforced bar and compression by concrete. It is not possible to provide a singly reinforced beam. Because we need to provide stirrups in beams.
Doubly reinforced beam:
The beam that is longitudinally reinforced in both tension and compression zone is called a doubly reinforced beam. Doubly reinforced can take reverse load. i.e., tension can be taken on both sides of the beam, which is not possible in case of singly reinforced, so shrinkage will be higher in Singly Reinforced Beams.

MohamedAquib
Bituminous Macadam is a Binder which is used for the 24-meter & 12-meter roads where the traffic movement is heavy. This can be laid in two or more courses for the better compressive strength. This shall comprise of 5 TO 7 percentage of bitumen. Semi Dense Bituminous Macadam is a binder that isRead more
Bituminous Macadam is a Binder which is used for the 24-meter & 12-meter roads where the traffic movement is heavy. This can be laid in two or more courses for the better compressive strength. This shall comprise of 5 TO 7 percentage of bitumen.
Semi Dense Bituminous Macadam is a binder that is laid after the BM course to obtain smoother finish on road surfaces. This is used in small roads of width less than 9 Meters. This course is laid directly on the wet mix macadam in smaller roads with a thickness of 25-30 mm. This shall comprise of 3 to 5 percentage of Bitumen.
