Good morning all ? i have one doubt please any one explain

[Venkatshanthi]

We are using cement in all civil work at correct ratio. but cement quantity exceed concrete or brick work or plastring what are the problem occurred

We can do measure a proportion for mixing of materials and its practically possible.

We are doing calculations with our assumptions and its completely theoretical.

What can cause the variation in the quantity;
1. First and foremost thing is the supervision level - if we fail to supervise the job, we will fail in reconciliation.
2. We assume x thickness and did work with y thickness.
3. Wastage of material happened due to poor workmanship.
4. Something is happening seriously wrong.

It is also a possibility that, i arrived at material consumption constant by doing wrong calculations or taking wrong parameters - it is good to check that first.

In plastering, in many cases, mason do dry shaking of cement and it can only be controlled with proper supervision, this can also increase the consumption along with weaker areas and possibility of leakages in future. if the Brickwork and RCC is not done correctly, you are going to deviate from the quantity you calculated and the consumption will be always on higher side.

Only way to identify why its consuming the more quantity is to have proper supervision and control on that activity.

Do observe the activity for one day correctly, you will get idea or you will find everything was executed as per plan without wastage.

In concrete case, many times the cement is consumed for patching of honeycomb, plastering of bulged portions, making of cover blocks etc. if there is poor control on activity and there is no record kept for consumption of cement for activity other than concrete, the counting of bags will always show consumption on higher side.

In case of brickwork the proportion we specified and proportion they use at site is important factor. another factor is the wastage of material which do happens due to setting of mortar in place.

In most of the case helper does a mixing of mortar an hour before going to lunch and throw it off after coming from lunch. it do happens and i too had seen those cases many time in past, best way is to ensure there is no new mixing of mortar done by gang an hour or half an hour before going to lunch.

If you find that, there is new batch is mixed in tray just before going to lunch, do ensure that gang goes to lunch after consuming that mix, this will help in reducing wastage and consumption of cement.

Also do ensure the mortar which drop down on floor is also consumed immediately by remixing.

For concrete u can do yeild test, related to cement usage check for part of cement adding with out any loss

Thank you sir?

Simple, add wastage and recalculate if mix ratio is correct
