Mix design and strength of soil–cement .

Saturated surface-dry condition of fine aggregate has been well defined in mortar and concrete production as the dry mass percentage moisture content where aggregate particles are saturated. However in soil–cement concrete construction, no mix design based on the saturated surface-dry condition of soil was attempted partly because the control of soil moisture on site is difficult.

Concrete can bleed due to poorly graded sand that allows water to bleed through the small channels formed due to voids in the sand or if the concrete is too wet. Insufficient mixing can cause segregation in the mix. For successful pumping, aggregate must have a full coating of cement grout to lubricate the mix as it is being pumped.
