Mixing of Concrete - Civil Snapshot

Dec 19, 2017  The process of mixing the ingredients of concrete by manual labour is called hand mixing. Hand mixing is adopted for small and unimportant works and where quantity of concrete used is small. Hand mixing method requires more cement (10%more) than machine mixing for obtaining the small strength of concrete.

Segregation in Concrete - Civil Snapshot

Jun 21, 2018  Introduction: Segregation can be defined as the separation of the constituent materials of concrete. A good concrete is one in which all the ingredients are properly distributed to make a homogeneous mixture. There are considerable differences in the sizes and specific gravities of the constituent ingredients of concrete. Therefore, it is natural that the materials
