Self loading concrete mixers can automatically produce and transport concrete on-site for its self-loading design, it is really efficient! During project, it loads materials by self, don’t need any other auxiliary equipment, and it has characteristics of small volume, four wheels-driving and steering. What’s more, it can discharge concrete at 290 degrees, which is much more convenient in all kinds of concrete production construction site, particularly small and narrow construction sites.Learn More Free Chat

Jan 24, 2019 · One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength.Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade; between 3,500 to 5,000 psi on suspended slabs, beams and girders; and walls and columns normally require between 3,000 to 5,000 psi.
All they ever check, so far as my experience, is the slump of the concrete, and of course they take concrete samples for lab testing to make sure the mix meets strength requirements. If the mix meets the strength requirement, and passes the slump test, so far as my experience goes, the concrete is fine.
