ABSTRACT:
A cement composition for which the mechanical properties of the set cement can be controlled independently of the slurry density, both at high density (>16 ppg) and at low density (<12 ppg) comprises a trimodal blend of particulate materials present as fine, medium and coarse particule size fractions, the particulate materials including cement, flexible particles, and a filler, characterized in that the cement comprises the fine particle size fraction, and the flexible particles and filler comprise the medium and large particle size fractions.
