Super-P in highrise concrete
Super-P in highrise concrete
(OP)
I posted similar thread at Stuctural Engineering other topics site, thread507-202506: Super-Plasticizer for high-rise concrete structure.
If ACI doesn't has any super-p requirements, do you kow any rule of thumb from concrete engineering points of view?
So far all I found out is to use super-p on 10,000psi or higher strength, on shearwall and/or columns with pump mix(pearock).
Remaining highrise concrete can be regular mix pumped to place for elevated slab without super-p or pump mix
Any advice?

RE: Super-P in highrise concrete
water reducer( super p ). Depending on the length of line you are pumping through, the mix can easily lose 2 - 3 inches of slump. With lightweight concrete, this loss is even higher. The admixture manufacturers have refined their product so much over the years that you can fairly easily dial in the slump you require without sacrificing strength through the addition of water.
