PRELIMINARY COMPOSITION OF SULFUR CEMENT AND METHOD FOR PREPARATION OF SUCH ADVANCED COMPOSITION OF SULFUR CEMENT

摘要

The present invention provides a preliminary sulfur cement composition containing sulfur cement and at least a polysulfide-containing organosilane in an amount of at least 0.3 wt.% Based on the total weight of the composition, the organosilane containing the polysulfide having a total molecular formula of which is an integer limits from 2 to 8, each of X and X 'independently denotes any hydrolysable group, each of n and n' independently is an integer ranging from 1 to 4, and each of m and m 'is independently an integer in ah 1 to (2n + 1). The invention further provides a method for preparing a preliminary composition of sulfur cement, a method for producing sulfur cement or a sulfur cement / aggregate composite, sulfur cement or a sulfur cement / aggregate composite, and using such a sulfur cement preliminary composition.
