Concrete Strength for Bored cast in place piles and
Having a lower concrete strength may be ok for axially loaded piles however it would not be ideal for piles subject to lateral loads as concrete strength plays a big part in avoiding brittle failure of the pile. Lower strength would likely increase the the amount of rebar required. This may counteract your 10-20% saving.
Depending on the class of concrete you're specifying (I'm talking CSA codes here) that dictates the minimum concrete strength. In most cases, we ar.The other baffling thing is that we say that the skipping piles requirement is to protect the concrete from vibrations caused by drilling or casing.durability is a primary consideration. A decrease in W/C ratio generally reduces permeability and makes the concrete more durable. It also results.cvg has nailed the reasoning why you should not add water. Especially if sulphate attack on the concrete is the main concern (which where I do 99%.We aren't in sulphate sensitive soils. The link he posted still seems to jive with the research that I found. Piles drilled 2 to 3 pile diameter.If you don't have a reason to require the higher concrete strength, i.e. exposure to sulphates or chlorides or freeze/thaw, then in theory you coul.Right, so theoretically I could just specify a 15 MPA or a 20 MPA concrete? Would the lower-strength concrete be more susceptible to damage from.It will be less than that percent reduction in cost. And yes, it would significantly less durable. If you have freeze-thaw issues you also need air.Quote (Page 12 of the OP's Referenced Study) The study involved only one concrete mixture design that nearly matches what MDOT normally uses in sha.It's possible to instrument and record adjacent ground vibrations to assure no damage to freshly placed concrete nearby. Sometimes it is specified.
