Abstract

Abstract:

With the development of mud changing to cement (MTC) technology, more attention is given to erosion of MTC slag block. In this paper, several probably erosion situation and mechanism of slag block are discussed. Laboratory testing results have showed that the slag block can resist erosion from NaCl、Na₂CO₃、Na₂SO₄and MgSO₄, but it is more likely corroded in acid medium such as NaHCO3solution. Many experiments are done in order to improve the resisting acid erosion capability of slag block. An effective way has been found that the resistant erosion capability in acid can be greatly enhanced by adding latex (10-15 percent of volume of mud) to slag slurry.

Key words: cement, erosion resistance, MTC, laboratory testing
