Tim Tucker,Steve Varosiuare high-performance slender (SHPS) columns were constructed and subjected to uniaxial and biaxial loading, with the aim of examining their performance. The key parameters investigated in the tests were the grade of HPC (ranging from M60 to M80), reinforcement ratios (ranging from 2.01 to 4.52%), a

Ole Naesbye Larsene concrete but is becoming expensive for various reasons. Also, the concern for environment is making the sand quarrying more and more difficult. Thus, there is a need of a cost-effective alternative and that is available in the form of manufactured sand (M-sand). In this experimental study, M-sand

The use of waste materials for part replacement of ordinary Portland cement (OPC) in SCC can enhance its mechanical properties. Fly ash (FA) is the most widely used pozzolanic material for making SCC. Its inclusion in concrete improves both the workability and strength of S
