Abstract:
A cementitious composition including cement, water, and a rheology modifying additive (RMA) is provided. The inclusion of the RMA improves the cementitiuous composition's response to vibration, and dampens out differences due to minor fluctuations in initial slump of the composition. The RMA may include a dispersant for cementitiuous compositions. The cementitious composition may optionally include other admixtures or additives known in the industry. A method for making the cementitious composition is also provided.
