Influence of glycerin grinding aid on the compatibility ...

The glycerin (GL) is commonly used as a grinding aid component in cement production, however it can bring poor compatibility between cement ground with it (GL-C) and polycarboxylate superplasticizer (PCE), which causes difficulties to construction. This paper studied the influence and its mechanism of GL on the compatibility between cement and PCE.
