Abstract
A dry cast cementitious composition including cement, water, and a rheology modifying additive (RMA) is provided. The inclusion of the RMA improves the dry cast cementitious 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 the dry cast cementitious compositions. The dry cast cementitious composition may optionally include other admixtures or additives known in the industry. Methods for making the dry cast cementitious composition and dry cast cementitious articles from the composition are also provided.
