Hi Ravi, If the spacing is only 2.7m, then with a hole 1.2m diameter the slab stops behaving like a continuous flat slab and you basically have short cantilever slabs from the columns either side of
Hi Ravi, You are not clear on whether this is in an existing slab or one that is being designed. In either case, it depends on the relative proportions- if the column spacings are say 3-4m, then probably
Hi Raj, The strength gain after 28 days depends on several factors, including method and length of curing, ambient conditions, mix design, ingredients (additives), etc. In general, you can count on
Hi Raj, Yes, you can cut cores anytime after 7-14 days (so long as concrete is hard enough not to disintegrate). Normally, they should be extracted and tested at 28 days strength, but 3 months is also
Hi Ravi, If your building does not have very stiff columns or shear walls, then the temperature analysis may not show up significant results. Remember also that the range of temperature variation has
