Abstract
Investigation was launched on cracking resistance of concrete with incorporation of different fibres in terms of mechanical performances, shrinkage and cracking sensitivity with employment of plate and temperature and stress test machine. Results indicated that little difference was observed on strength, Young’s elastic modulus and autogenous volume deformity among concrete made from different fibres, and incorporation of PVA fibres elevated the ultimate tension by 8 per cent in comparison with the referenced concrete while PP fiber showed no obvious effect. Cracking resistance of concrete was improved from Grade V to Grade I with incorporation of PVA and PP fibres through plate method and concrete made with PVA was rated better in cracking resistance because of lower cracking temperature according to RILEM TC119. Based on investigation launched above, PVA fibre was finally selected and so far the dam was in good shape and runs well.
