    摘要: A method for controlling at least one workability parameter of a concrete contained in the container of a mixer with a non vertical rotational axis, includes making the container turn at least at least two different rotational speeds; determining, for each of the rotational speeds, a rotary drive torque C of the container, a value of shear stress r of the concrete and a speed gradient γ of the concrete according to the following relationships: τ=T(ω)·C and γ=G(ω). ω where T and G are predetermined functions; determining a relationship of variation of shear stress τ according to the speed gradient γ by extrapolation and/or approximation from the determined values; and providing an indication of the workability parameter of the concrete based on the relationship variation.

    摘要: An apparatus for measuring attributes such as color, thickness and/or retro reflectivity of a road marking disposed on a road surface. The apparatus includes a vehicle that travels over the road surface. The vehicle transports a measurement system and a computer. The measurement system includes at least one subsystem, which may include a color measurement subsystem, a thickness measurement subsystem and/or a retro-reflectivity measurement subsystem. The computer receives the measurement information from the measurement system.

    摘要: Apparatus in which cement clinker is crushed at a temperature of 1,000* to 1,450* C., is then brought, while passing through a reducing atmosphere for between 1.5 and 6 minutes, down to a temperature in the range 700* to 1,100* C., is then subjected to rapid cooling by the application of atomized water to reduce the temperature to approximately 300* C. while excluding oxygen, and is finally collected in free air, thorough contact with the reducing atmosphere and the subsequent rapid cooling being ensured by carrying out these stages while the clinker is vibrated down an incline from the exit of the crusher to its point of collection in the atmosphere.
