How we can reduce wastage of Concrete during pumping of concrete?

yes obviously
for cement
on cement bag some standard information should be printed like the type of cement, pozzolana content, IS code of that type, week of packing,
it should have a greenish color
it should give smooth feeling when putting your hand in cement bag and doesn’t present any lumps
When it throw on the water surface, it should stay on the surface before the sink for some time.
cement bag should be used within three months of manufacturing
for sand
Basically, we check clay content in the sand by sand, taken in hand, and rub it. If there is clay is present, then particular clay sticks with hand moisture so we can observe easily.
sand should be washable
We can also check its uniformity by sieve if it’s present on site.
aggregate
aggregate should have well-graded we can check it by check packing (interlocking structure ) of it
aggregate should not have any clay contain
and other material we can check it by various experience .

Estimate pouring speed and match it production speed to avoid waiting and approaching it’s setting time, keep home work-ready with trials for options (e.g., redosing with SP) for reusing leftover concrete, inform Batching plant when 10% of the pour is balanced and reduce trucks carrying concrete thereafter, explore the scope for casting precast blocks from leftover / used in testing, etc. concrete,
Deploy a supervisor to be in touch with Batching Plant from site to hold or slow down concrete supply if there is any issue at the site, keep critical spare parts of Concrete Pumps, etc. available at site 24 x 7, deploy an experienced Pump operator and a Concrete specialist at the site
1. Small precast forms(curbs, drain slabs, etc., which are needed in the project) to be kept ready at the site near the RMC pouring area fresh concrete waste needs to be handled into these forms. Optimum labor to be maintained to handle these operations.
2. Retrieve the aggregates by washing off the waste concrete.
3. Order the right quantity of concrete required to finish the pour, hence reducing the wastage.
4. Have at least one spare pump at the site when pouring a large quantity of concrete.
5. Have the right waste concrete segregation pits at RMC plants to wash the wet concrete and to retrieve the coarse aggregates.
