| Summary: | The strength of ultra high strength concrete (UHSC) with axial compressive strength
more than I 00 MPa is presented in this paper. There are mixes have been cast in this
project. Based on the slump test, the compression tests with twelve cubical specimens
(150mm) at 3 days, 7 days, 28 days and 90 days, split cylinder tests with six cylinder
specimens (I OOmm x 200mm) at 28 days and 90 days; and porosity test with two
slabs (200mm x 300mm) for twelve coring specimens at 3 days, days, 28 days and 90
days, the compressive strength of UHSC with ratio of cement on fine and coarse
aggregates are to I: 1.5:2.5, 2.5%, 3% and 4% of superplasticiser, 10% of silica fume
and; 25% and 27% of water cement ratio are to be investigated. The observation of
strength on each specimen with various percentage of superplasticiser will be made
up to 90 days of strength. Graph of stresses vs. days will be plotted for further
analysis as well as the calculation of modulus of elasticity (E). |
