New mixing technology requires flexibility that meets technical and environmental standards. Mobile plants are favored for their ease of use and continuous advances. SBM Concrete Mixing Technology's super-mobile wheeled concrete mixing plants don't require foundations and can be put together in eight hours to any site accessible by lorries. Reduced construction site transport and lower lorry traffic can reduce carbon emissions by up to 25%.
Mixers are also being developed with portable and non-portable options. Astec's external mixer can be either a twin-shaft timed coater or a rotary mixer. Other than self-load mixers, dumpers are also becoming popular for their performance on rough terrain and higher load capacities. Spanish company Ausa has seen a rising demand for their dumpers in golf course construction and maintenance. The dumpers come with concrete chutes as an attachment and use low degradation tires to avoid grass damage. The benefits include cost savings from pumping, truck, and generator set rentals and environmental benefits from reduced transport, time, energy, and the reduction of required materials.
