Hand mixing• For small and unimported jobs concrete is mixed by Hand using showels.As mixing of concrete is not eficient throughtly ,it is advisable to add 10 persent CEMENT.• For hand mixing a brick platform is prepared by laying the bricks on the ground.It must be 2 m wide and 3.5 m long.
shooters, coreboxes, gassing apparatus and similar equipment are also necessary. The mixing principles that dominate the German foundry industry will be described below. The purpose of blending a molding sand mix is to coat the refractory matrix components with the gas-curing resin and activator. The following facts illustrate the enormous effort
The materials used in this research were Sand, Portland Cement, Earthen Materials (laterite, clay), while the Constructed Multipurpose Brick/Block Moulding Machine, Compression Testing Machine, Shovels etc were the instruments/tools used. The machined was designed to produce bricks/blocks enough to build a two bedroom flat in five days.
Milling machines can be found in a variety of sizes and designs, yet they still possess the same main components that enable the workpiece to be moved in three directions relative to the tool. These components include the following: Base and column - The base of a milling machine is simply the platform that sits on the ground and supports the machine.
