description |
The ultra high strength concrete was analyzed using conventional methods such as following the American Society in Testing and Materials (ASTM), British Standard code of Practice (BS) to carry out mechanical testing for the concrete.The mechanical test analysis determined that the increased compressive strength of the
specimen was proportional to the age of specimen and the type of curing methods. Air-cured
specimen on day 28 was found to be higher in compressive strength than the other methods, and
this could be due to the water cured specimen from this project being directly taken out and
tested within the same day. However in literature papers, specimens undergoing water cured
were brought out a day in advance to allow excess water to be evaporated that might have
resulted in the much higher strength. The modulus of elasticity test was conducted based on the
specimen age of 28 under water-cured condition. The result was determined and compared
against compressive strength with a COV of less than 10%, indicating consistency and
accuracy. The inclusion of supplementary materials such as slag cement and silica fume, with
its chemical properties will chemically agglomerate the particles together, giving a more
cohesive and dense mix. Through the experiment conducted supplementary materials will allow
for a higher initial strength increment as compared to one without any supplementary materials.
Moreover, the effects and influences that slag and silica fume possessed was determined by
experimental test and literature research to define its actual influence and is useful in the
making of UHSC for it to be durable and sustainable. |
