Hand Mixing of Concrete -Procedure and Precautions
Concrete is mixed by any two methods, based on requirement as per quality and quantity of concrete required. Normally for mass concrete, where good quality of concrete is required, mechanical mixer is used. Mixing by hand is employed only to specific cases where quality control is not of much importance and quantity of concrete required is less.
