History
[with blades.] On February 9, 1904, the first portable concrete mixer was patented by Richard Bodlaender, an inventor from Breslau, Germany. This concrete mixer was horse-drawn and called 'Mortar Mixer'. It worked by replacing the front wheels with a large drum that held large paddles for mixing the cement. [Exchequer Dam.] Roscoe Lee was granted a patent in 1934 for his transit concrete mixer design. This design made it possible for new trucks to be turned into concrete mixers by using a crane to put a drum on the back of the truck. It was less expensive than a cement truck dedicated to only carrying cement and allowed the trucks used to continue to be adapted for other things. Concrete mixers have continued to advance. Recently, research detailing a forward simulation model of an energy-saving concrete mixer using hydraulic technology was released based on Matlab/Simulink technology.

Trucks and trailers
[used as a weight reduction measure.] Most cement trucks weigh a substantial amount empty, meaning they have very heavy tare weights. Federal weight laws under the Federal Bridge Forumula (FBF) require a three-axle ready mixed concrete truck to weigh 48,000 lbs or under. This leaves only 18,000 lbs for concrete to be carried, as 30,000 lbs is the tare weight of the truck.

Outline of proposed changes[edit]
I was thinking of adding more to the history section. That will be my primary edit. I would like to add more information on the inventor(s) of the cement truck, the purpose behind making it, and the advancements made throughout the years. I would also like to add more pictures to the article and correct the citations that need verification, as there are quite a few.
