The ease with which one can work with concrete is called workability. It is one of the physical parameters of concrete which affects the finesse, strength and durability. This can be tested by slump test. The apparatus for conducting the slump test essentially consists of a metallic mould in the form of a frustum with a cone with bottom dia. 20 cm, top dia. 10 cm and 30 cm height with a base plate. A steel rod with 16 mm dia. and 60 cm height is to be used for compacting. The internal surface of the mould should be thoroughly cleaned so that no moisture or any hardened concrete is not left in it. The mould is placed on a plain, smooth and a non-observant surface. Concrete is then placed in four layers with each layer approximately one-fourth of the height of the mould. Each layer should be tamped 25 times evenly using the round end of the tamping rod such that the strokes are uniformly distributed over the cross section. After the top layer is tamped it is well level with the help
Tekla Structural Designer is an advanced software used for Structural Analysis and Design of a Building. In Tekla we can do detailing of steel structures as well as RCC structures. We can create RCC buildings and we can insert the rebars in Tekla structures Designer software. We can also do the form works and structural drawing without the help of any other software .
