This invention relates to a rubber composition comprised of at least one diene-based elastomer and rubber reinforcement comprised of fibrillated aramid fiber micropulp and reinforcing filler comprised of pre-hydrophobated precipitated silica. Such fibrillated aramid micropulp is comprised of micronized fibrillated aramid fiber pulp. Such pre-hydrophobated precipitated silica is comprised of precipitated silica pre-treated with at least one of bis(3-trialkylsilylalkyl) polysulfide, alkoxyorganomercaptosilane, optionally together with an alkylsilane. The invention further relates to such rubber composition wherein said reinforcing filler is comprised of a combination of said pre-hydrophobated precipitated silica as a precipitated silica pre-treated with an alkoxyorganomercaptosilane and a precipitated silica wherein said pre-hydrophobated precipitated silica and said precipitated silica are both hydrophobated in situ within the rubber composition with a bis(3-trialkoxysilylalkyl) polysulfide. The invention further relates to tires containing at least one component comprised of such rubber composition such as for example a tire tread.

One example of correlating energy to mix well cement slurry under laboratory conditions to field conditions can be implemented as a method to determine energy to mix cement slurry. Electrical power supplied to an electric mixer in mixing a specified well cement slurry is measured. An energy to mix the specified well cement slurry is determined from the measuring. The determined energy to mix the specified well cement slurry and specifications of field equipment for use in mixing the specified well cement slurry at a well site are compared. The field equipment is a different configuration than the electric mixer. Based on the comparing, it is determined whether the well cement slurry needs redesigning according to capabilities of the field equipment.
