· The dry premixing process also provides high flexural strength, slightly improved drying shrinkage, and better flow compared with cementonly mortars. The strength and shrinkage results improve when ternary blend cements are used and the dry, premixing process is more effective as the obinder ratio increases.
· The dry premixing of sand and cement shows promise of improving the properties of mortar and concrete. Our final runs confirmed several of our theories about how the mixing equipment operates and that it may be possible to reduce cement content and produce mortars of acceptable strength using the dry, premixing process.

The aim was to study the efficacy of a new method for dispersing cement in sand to produce a mortar with better mechanical and physical properties. This strategy was found to work best at high sand/cement ratios, indiing that the dry premixing is more effective as the cement content is reduced and that it may be possible to produce commercially acceptable mortars with lower cement .
