High strength concrete mix design pdf.
Understand concrete mix design submittal and approval process for ncdot know how to correctly complete ncdot mix design forms.
Quikrete concrete mix exceeds the compressive strength requirements of astm c387 as shown in table 1.
This design guide serves to extend the use of concrete beyond grade 60 in the design of concrete structures using cp65.
The use of this quality mixture ensuring your finished project will last you for years to come.
Hence it is intended for use by engineers familiar with the design of concrete structures using particularly cp65 but who have little or no experience of high strength concrete hsc.
The dry rodded bulk density of c a.
Table 1 typical compressive strength1 compressive strength astm c39 age typical values 7 days 2500 psi 17 2 mpa 28 days 4000 psi 27 6 mpa slump range 2 3 51 76 mm 1.
For a given type of cement and aggregates used the reference number corresponding to the design strength at a particular age is interpolated from figure 1 to 4.
The mean design strength is obtained by applying suitable control factors to the specified minimum strength.
Iii high early strength iv low heat of hydration v high sulfate resistance ncdot table 1024 1.
The development of high strength concrete hsc in china occurred in two stages.

The initial stage began in the 1950s when hsc was studied and applied to prestressed concrete structures.
Mix design of high strength concrete procedure.
Now what is mix design.
Sakrete high strength concrete mix is a preblended mixture of sand coarse aggregate and cementitious materials.
For new construction or repairs where concrete thickness exceeds 2 inches you ll want to count on a preblended mixture that can.
The specified design strength of concrete is 30 mpa at 28 days measured on standard cylinders.
Water water cement ratio.
