What is CNC waste…????
CNC waste is waste obtained from Computer Numeric Controlled Lathe Machines.
Annual CNC waste collection is about 1200 Million tonnes.

It is the very first thing a techno-manager does when he/she takes up a project.
As we are selling cement Bags; as same as we can sell Green Concrete/Mortar Bags with Dry Mix.
There are areas where concrete is not required in very large scale there these can be produced.
For making Green concrete there is not high technology requirement.
Implementation of this idea will help to use the waste products in large scale.

These Green concrete bags are easy to transport; with various mix designs M20, M25, M30 etc.
Instead of transporting various ingredient of concrete and storing differently; Green concrete Bags can be purchased.
Managing and handling of these bags are not much difficult.
Site engineer need not to look after about Mix proportions all the time, as the Bags are already mixed as per the design.

Technically it is found that adding 2% CNC Lathe waste with 50% alteration of NCA by RCA will provide sufficient strength.
Unskilled laborers are in most of the sites, these green bags will help in managing the projects technically.
Till 3 months time the dry mix can be used technically.

CNC Lathe wastes reacts with Env. And get corroded; these eventually affect the environment.
Waste aggregates poses great threat of land. Also these will interact with open environment.

It will save the storage cost of 3 different materials.
It uses the waste materials so according to the research work undergone, it will save around 35% of cost.
It will reduce the 3 time transportation costs.
Per cubic meter it saves 30% cost as compare to normal concrete.

It acts to be an Environmental savior. Due to lack of dumping sites in the present scenario, so there is need to save the land, this process leads as the savior of environment.
This process can be assumed to be the economical process as less transportation costs require and also the construction cost is less.
To produce and secure a system of sale based packed premixed concrete batches, in which CNC waste and recycled coarse aggregate concrete will be present.
