The strength of brick masonry depends upon the strength of bricks used in the masonry construction. The strength of bricks depends upon the nature of soil used for making and the method adopted for molding and burning of bricks. since the nature of soil varies from region to region, the average strength of bricks varies …
While estimating quantity of concrete for particular structural work, we normally consider 3-5% as wastage. But concrete waste more than that can increase the cost of project and may impact project progress. So, it is necessary to control the concrete wastage at site. Concrete wastage can be prevented by proper planning of pour. Concrete pour cards shall …
There are different types of cement, but Portland cement is the binder used most widely. Although Portland cement is named after an area in UK where its use was originated, today it is manufactured all over the world.
Admixtures confer certain beneficial effects to concrete, including reduced water requirement, increased workability, controlled setting and hardening, improved strength and better durability. Admixtures are materials other than cement, aggregate and water that are added to concrete either before or during its mixing to alter its properties, such as workability, curing temperature range, set time or color. Many …
Concrete is a composite construction material. which consists mainly of relatively inert mineral matter in the form of particles or fragments held together by a binding medium which gives concrete its solidity and strength.
Now a day’s Aluminium formworks used to construction for High Rise Buildings. Probably the most versatile modern construction system, aluminium formwork system. This produces a lightweight panel with an excellent stiffness to weight ratio, yielding minimal deflections under concrete loading.
