Abstract This paper presents the details of optimized mix design for normal strength and high performance concrete using particle packing method. A critical review of mix design methods have been carried out for normal strength concrete using American Concrete Institute (ACI) and Bureau of Indian Standards (BIS) methods highlighting the similarities and differences towards attaining a particular design compressive strength. Mix design for M30 and M40 grades of concrete have been carried out using ACI, BIS and particle packing methods. Optimization of concrete mix has been carried out by means of particle packing method using EMMA software, which employs modified Anderson curve to adjust the main proportions. Compressive strength is evaluated for the adjusted proportions and it is observed that the mixes designed by particle packing method estimates compressive strength closer to design compressive strength. Further, particle packing method has been employed to optimize the ingredients of high performance concrete and experiments have been carried out to check the design adequacy of the desired concrete compressive strength.

Mixture Ratio

The test in order to obtain liquidity, higher intensity ultra-high performance concrete(UHPC), in the course of preparation, high intensity quartz sand to replace the ordinary sand,reasonable mixture ratio control low water-cement ratio,the incorporation of part of the test piece ofsteel fibers, produced eight specimens . In the ordinary molding and the standard conservation 28d thecase, the ultra-high-performance concrete compressive strength of more than 170MPa.Thepreparation of the test method and test results will provide the basis for further study of the law of themechanical properties of ultra high strength properties of concrete.

Chloride Attack

Concrete is the main material used in most of structures in the world. The use of high strength and high performance concrete to overcome deterioration due to static and dynamic load and some environmental burden in different situation such as chloride attack, sulphate attack and etc, is increasing worldwide. Achieving to a concrete with a high quality and saving in amount of material used for producing the concrete need a proper mix design method taken into account. DOE method is considered as an effective and substantial method in implementing the concrete mix design. In this paper, specifications and all mix design calculation steps using DOE method in achieving a high strength and high performance concrete for a tall building in a coastal environment based on three concrete cubes specimens produced in the lab, are investigated. The 7 and 14 day compressive strength test were implemented on the concrete cubes. At the end, it concluded that the specified compressive strength (45 N/mm2) can be achieved on the 28th day based on DOE method.
