(a) Variation of 7-day compressive strength with
superplasticiser content for mix A
Fig 3 Variation of moudulus of rupture with
superplasticiser content for mix A and mix B

(b) Variation of 28-day compressive strength with
superplasticiser content for mix A and mix B

Fig 4 Variation of split tensile strength with
superplasticiser content for mix A and mix B

Fig 2(b) also shows the variation of 28 day
compressive strength for mix B with the percentage
of superplasticiser. From the figure it is evident
that the behaviour of mix B is similar. Figs 3 and
4 show the variation of modulus of rupture and
(c) Variation of 180-day compressive strength with split tensile strength for mix A and mix B, with the
superplasticiser content for various mixes
percentage of superplasticiser. It can be observed
that replacement of sand by stone dust increases
Fig 2 Variation of compressive strength with
superplasticiser content for various mixes the modulus of rupture and split tensile strength
of both the mixes.
