Experimental Study and Performance Analysis of Concrete Shrinkage-Reducing Agents

Abstract:

This paper will focus on developing a sort of concrete shrinkage-reducing agents that are generally some surfactants on the basis of some tests. By reference to the main chemical components of some domestic and foreign agents, the following chemicals are initially selecting : tert-butyl alcohol, triethanolamine and polyvinyl alcohol, and then some experiments about these substances were made, including liquid surface tension test, high-strength cement mortar shrinkage test, mortar strength test. Finally, the medicals that can significantly reduce drying shrinkage deformation but have little effect on the strenth of concrete blocks,are selected out as available concrete shrinkage-reducing agents.
