Experimental Investigation on Compressive, Tensile, and Flexural Strengths of Concrete with High Volume of GGBS, Fly Ash, and Silica Fume
An experimental investigation was carried out to study the performance of high-strength concrete with a high volume of mineral admixtures. Two concrete mixes were prepared, an ordinary concrete and high-strength concrete with target compressive strengths of 35 and 90 MPa, respectively. The ordinary concrete was produced without mineral admixtures while the high-strength concrete was produced using ground granulated blast-furnace slag (GGBS), fly ash, and silica fume in a weight ratio of 30%, 20%, and 10%, respectively. For each concrete mix, twelve cubes, six rectangular prisms, and twelve cylinders were prepared simultaneously. The experimental program consisted of destructive tests including compressive, tensile, and flexural strength tests as well as non-destructive tests including Schmidt hammer and ultrasonic tests. In the destructive testing part of this study, the cubes were tested in compression, the prisms were tested in flexure, and the cylinders were subjected to splitting tensile load. The compressive strength at 28 days was 41.72 MPa for ordinary concrete and 96.53 MPa for high-strength concrete which is 19.2% and 7.26% higher than the target strengths of the two mixes, respectively. The experimental flexural strength of the high-strength prisms was 6.17 MPa which is 8.45% higher than the target value. The splitting tensile strength of high-strength concrete was 1.59 times that of ordinary concrete. Concrete made by a high volume of GGBS, fly ash, and silica fume ratios demonstrated superior mechanical properties which exceeded the target design strengths.
