| Summary: | The results of an e
xperimental
study on
the
high strength concrete
(HSC)
with different f
ine aggregate is presented. The
study mainly concern on the
influence of the characteristic of shape and texture of
the
fine aggregate on
mec
hanical prope
rties of HSC
. Two types of fine aggregate were
used namely
crushed granite sand and natur
a
l river sand. The HSC mixtures
consist of
high
cement content of 530 kg/m
3
and low water
-
cement ratio of 0.30
was
selected.
The
presence of crushed rock dust in crushed rock sands that influence the
mechanical properties of HSC was also considered in this study.
HSC mixtures
comprises of crushed granite sand with various percentage of crushed granite dust
content
such as 0, 5, 10 a
nd 15%
were prepared
. The compressive strength of the
HSC was determined by conducting a series of cube compression tests. The
experimental results
indicated that: (a) The performance of HSC in term of
compressive strength was superior with crushed granite
sand (angular and rough
grains) rather than natural river s
and (rounded and smooth grains). (b) amount of
10% of crushed granite dust content was found to improve the compressive
strength of the HSC mixtures, thus, the 10% was considered as the optimum du
st
content because the compressive strength of the HSC decreased slightly as the
content of crushed granite
dust increased to higher amount of 15 %. |
