CONCRETE SHIRINKAGE-REDUCING COMPOSITION COMPRISING CARBOXYLIC ECO-FRIENDLY COMPLEX COMPOSITION AND FLUOROSILICATE-SILICA-ALUMINA COMPOSITE AND PRODUCING METHOD THEREOF

摘要

The present invention relates to a concrete shrinkage reducing composition using a carboxylic eco-friendly complex compound and a fluosilicate salt-silica-alumina composite, including the carboxylic complex compound and the fluosilicate salt-silica-alumina composite, obtained from a byproduct occurring in a process of manufacturing an aromatic compound. The concrete shrinkage reducing composition can prevent harmful organic materials as well as environmentally harmful heavy metals from being detected, and can obtain an effect which is equivalent to or higher than a conventional shrinkage reducing composition while using eco-friendly materials and at the same time, reducing the content of fluosilicate salt.
