Time-Dependent Dimentional Changes (Shrinkage) of Mass Concrete Incorporating Local Egyptian Blended Cements
Journal Title: BEST : International Journal of Management, Information Technology and Engineering ( BEST : IJMITE ) - Year 2017, Vol 5, Issue 6
Abstract
The purpose of this study is to examine the effects of using different Egyptian cement types and supplementary cementing materials (SCMs) to control the time-dependent behavior (shrinkage) developed in mass concrete and hence, enhance its sustainability. Three different types of cements of grade 32.5 were used. For each binder type, two concrete mixes (w/b ratio 0.5 and 0.6)are used to examine the effect of w/b ratio on the strength and shrinkage behavior of mass concrete. Shrinkage tests were conducted on the concrete prisms of dimension (100 x100 x 400) mm. A comparison was carried out between shrinkage behaviors of all concrete mixes. The results show that the maximum shrinkage value decreases with increasing SCM and with using (CEM II-B-L) and (CEM II-A-S). The shrinkage was decreased by29% for CEM II-A-S and 5% for CEM II-B-L with respect to CEM I. It was also decreased by17%, 25%, and 44% in case of using 30%, 40%, and 50% fly ash replacement respectively.
