Thông tin tài liệu:

Nam O marine sand percentage adding was mentioned via DCS and nDCS variations in design time from 3 days to 90 days. Results highlight Nam O marine sand adding to concrete fine aggregate mix gives a dramatical changes of DCS and nDCS before 28 days and non-change for a time after 28 days to 90 days. The DCS is higher from 5 to 10% than nDCS for using this study marine sand and that provide many considerations in term of local material.
