Can you please suggest concrete mix that can act as slurry cum concrete of grade M40, as we wanted to avoid cost incurred due to slurry which is waste once concrete flow in and it will also save time majorly

you need to lubricate pipeline before start of the concrete so you can either use a slurry or ready made lubricant available in market which are also cheaper than producing slurry. Cost incurred due to slurry will be always negligible when comparing to make a concrete like slurry (SSC - self compacting)

whether this can be left in as part of concrete, as disposal of such lubricant is one more issue

Dear Sir,

One of our client asked the ratio for cylinder/cube is 0.8 in harden concrete after 28 days. But in is 456 cylinder/ cube ratio for core sample is 0.8.but as per ASTM, ACI for higher grade minimum cylinder strength should be Fck of the design. Is there any reference for ratio 0.8 or it is compulsory cylinder/ cube 0.8 is must?

Kindly clarify


Thanks & regards

The carried load by a cube and cylinder varies for same grade due to height. you can make a concrete and cast few cubes and few cylinders and then do comparative testing for minimum 30 trials. You will arrive to something similar.

Sir,
There is a question,
What is apparent specific gravity and how it differs from specific gravity?
Dnyan Deshmukh
Dnyan Deshmukh
All materials do have voids in it, calculation of specific gravity do take long time when the material goes denser with less voids.

Apparent specific gravity is the one which is calculated without reducing the volume of voids.

Specific gravity is calculated using pycnometer bottle.

To calculate exact specific gravity, say for aggregates, one need to make aggregate in SSD condition by immersing them in water for at-least 24 hours before test.
