Restrained cracking at early age of conventional concrete are mainly due to improper curing or plastic shrinkage and may be avoided by quality workmanship. However, the autogenous shrinkage in high strength concrete or high performance concrete is inevitable even good curing process has been taken after placing. In this investigation, steel fibers and polypropylene fiber were introduced to concrete mix so as to reduce the autogenous shrinkage. Besides, Aluminate-base low shrinkage cement was used to replace part of Portland cement. The main results and findings are summarized based on the tests of autogenous shrinkage measurements.application/pdf40205 bytesapplication/pdfzh-TW國立臺灣大學土木工程學系暨研究所Volumetric StabilityAutogenous ShrinkageSelf-compactabilityPozzolanic Materialsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/2666/1/872211E002064.pdf
