Analysing the Micro Structure of Sea Sand Concrete

Abstract

The microstructure of sea sand concrete wes characterized by the Accelerated Surface Area and Porosimetry System (ASAPS) to detect the concrete micro-prorous structure distribution, the Tabletop Scanning Electron Micro-scope (TSEM) to analysis the sea sand concrete internal microstructure, as well as the X-Ray Diffractometer (XRD) and the Thermal gravimetric/Differemtial Thermal Anylyzer (TG/DTA) to observe the composition of concrete in this paper. The influence on hydration processes of concrete caused by sea sand was reseached from four aspects which are the influences of fly ash on concrete, chlorine salts on sea sand concrete, chlorine salt on fly ash added sea sand concrete and desalination sea sand and not desalination sea sand concrete micro structure features to evaluate the effect of sea sand on regular sea sand concrete and fly ash added sea sand concrete micro structure features and chemical composition.
