CONCRETE MIX DESIGN GRADE M60 a DESIGN STIPULATION Target strength = 60Mpa Max size of aggregate used = mm Specific gravity of cement = Specific gravity of fine aggregate = Specific gravity of Coarse aggregate = Dry Rodded Bulk Density of fine aggregate = 1726 Kg/m3 Dry Rodded
The purpose of concrete mix design is to ensure the most optimum proportions of the constituent materials to fulfill the requirement of the structure being built Mix design should ensure following objectives 1 To achieve the designed/ desired workability in the M80 80 e Factors influencing Choice of Mix Design
Imagine a concrete mix composed of a single sized aggregate and cement paste only In order to fill up all the gaps between the aggregate particles so as to drive away the air voids in the concrete mix the volume of cement paste must be larger than the volume of gaps within the aggregate skeleton Figure 1 a If instead of a single sized
Ferdous Kayali and Khennane 2013 developed an alkali activated concrete mix design by considering workability specific gravity of the materials the concrete density variability air content and the compressive strength requirement The activator/fly ash ratio has been considered initially and then it determined the precise activator
Imagine a concrete mix composed of a single sized aggregate and cement paste only In order to fill up all the gaps between the aggregate particles so as to drive away the air voids in the concrete mix the volume of cement paste must be larger than the volume of gaps within the aggregate skeleton Figure 1 a If instead of a single sized
4 The mix design of concrete takes into account various factors such as the compressive strength required the type and size of aggregates the water cement ratio the shape of coarse aggregates the workability needed the exposure conditions and the type of cement used
The mix design for the M80 and M100 grades is composed of the basic concrete material The admixtures of the Alco fine and the Metakaolin are replaced with the 15% of the total binder content Further the composition of the materials in association with the chemical admixture is discussed further below in this study
The objective of this experimental study is to propose a mix design methodology for self compacting geopolymer concrete SCGC considering various influencing parameters recommended for self
This paper proposes a mix proportions for M80 grade Self compacting concrete SCC based on Nan Su mix design principles First the amount of aggregates required is determined and the paste of binders is then filled into the voids of aggregates to ensure that the concrete thus obtained has flowability self compacting ability and other
