Mitigation of plastic shrinkage cracking with natural fibers - kenaf, abaca, coir, jute and sisal Open
In this study, a number of different fibers - namely kenaf, jute, abaca, coir and sisal - were investigated as natural alternatives to polypropylene (PP) fibers for reducing plastic shrinkage cracking. The risk of plastic shrinkage crackin…

Prestressing low clinker structural concrete elements by ultra-high modulus carbon fibre reinforced polymer tendons Open
The combination of low clinker high-performance concrete (LCHPC) and ultra-high modulus (UHM) carbon fibre reinforced polymer (CFRP) tendons was recently proposed for prestressed structural elements. The 70% reduction in cement content res…

Comparison of Pozzolanic Additives for Normal and High Strength Concrete Open
Microsilica is widely recognized as a “benchmark” for pozzolanic products. Although microsilica is an industrial byproduct, it has recently become very expensive. Four different pozzolanic additives were compared by the authors of this stu…
