The Impact Strength of High Strength Self-Compacting Concrete with Metakaolin and Silica Fume
One of the methods used to assess the strength of concrete is by evaluating its resistance to impact loads, which is the total initial energy required to make concrete crack until it collapses completely. This method comprises of the use of Metakaolin and silica fume as partial substitutes of cement in concrete mixtures, which causes environmental pollution. Therefore, this research aimed to determine whether the concrete could qualify as High Strength Self-Compacting Concrete (HSSCC) with good impact resistance. Impact strength tests were carried out using the Drop-Weight Test method. Metakaolin was included at a rate of 12.5%, with varying percentages of silica fume, which ranged from 0 to 15% of the binder weight. Furthermore, cylindrical specimens with a diameter of 150 mm and a height of 60 mm were tested at 28 days of age. The results showed that the incorporation of metakaolin and silica fume as pozzolans in the mixtures enables the concrete to qualify as HSSCC. The impact strength values of HSSCC with metakaolin and silica fume of 0%, 9%, 11%, 13%, and 15% at crack initiation were 6687.97 J, 28,561.82 J, 35,889.89 J, 33,373.62 J, and 28,352.93 J. Furthermore, the impact strength values at total collapse were 6732.11 J, 28,605.96 J, 35,934.96 J, 33,417.77 J, and 28,396.27 J, respectively. In conclusion, the use of metakaolin and silica fume effectively enhanced impact resistance of HSSCC, which offered a potential solution to improve the durability and sustainability of concrete structures.
