    摘要: The lubricant base oil of the invention has excellent energy-conserving performance, low-temperature viscosity characteristics, and detergency. The composition contains: (A) a lubricant base oil composed of, based on the total base oil amount, 50 to 99.9 mass % of a lubricant base oil having a 100° C. kinematic viscosity of 1 to less than 5 mm2/s, and 0.1 to 50 mass % of a lubricant base oil having a 100° C. kinematic viscosity of 5 to 200 mm2/s, and (B) a viscosity index improver having average Mw of not less than 10000, and a Mw to PSSI ratio of not lower than 0.8×104, wherein the composition contains 0.1 to 50 mass % of component (B) based on the total composition amount, and has a 100° C. kinematic viscosity of 3 to 15 mm2/s and a 150° C. to 100° C. HTHS viscosity ratio of not less than 0.50.

    摘要: An improved composition for and method of priming a concrete pump line is provided. The flowable composition comprises a solid particulate mixture and water, the particulate mixture being comprised of solvatable polymeric material preferably selected from a group consisting of polyacrylamide, polyacrylate and mixtures thereof; an organic complexing agent preferably of urea; and a buffering agent preferably of citric acid. The invention provides a flowable composition exhibiting improved coating and lubrication to the inner walls of a concrete line as it passes therethrough. The flowable composition mixes quickly with water to form a clear solution, hydrates quickly upon being mixed with water, and provides a composition for use in priming concrete pump lines that does not utilize cement or priming grout slurry.
