Concrete Mixing Methods and Concrete Mixers: State of the Art

2.1.2 Pan Mixers . All pan mixers work on basically the same principle []: a cylindrical pan (fixed or rotating) contains the concrete to be mixed, while one or two sets of blades rotate inside the pan to mix the materials and a blade scrapes the wall of the pan.The shapes of the blades and the axes of rotation vary. Figure 4 shows the different combinations of blade configurations and pan.

Carbon Footprint of Recycled Aggregate Concrete

Emissions for concrete with 0.5 w/c were between 347 and 351 kg of CO 2 - e /m 3 . It was also corroborated that cement is the material with the greatest influence on greenhouse gas emission generation in the concrete's production phase, regardless of the use of recycled or aggregates.
