Different Types of Concrete Mixer or Concrete Mixing Machines

Concrete mix obtained by this mixer is collected batch by batch and time by time. So, it is called as batch mixer. After pouring all the materials into pan or drum, it mixes all of those for some time and finally discharges. This process is repeated until required amount of concrete mix is obtained. In general Batch mixers are two types.

Ready-mix concrete - Ready-mix concrete is concrete that is mixed at a central mixing plant and brought to the construction site in a ready-to-use condition. One should take care of the time required for transportation while using ready-mix concrete as the mixture can harden if there is an undue delay.

The Easy Guide to the Best Cement Mixers for 2021

An important point to note here is the 17-inch drum opening, that's a really good size for getting that premixed cement in and the finished mix out.. The thing that really impressed us was just how much that drum can hold. With its 3 steel blades that offer mortar/concrete configuration, It can hold up to a whopping 300 lbs of premixed concrete, and still manage 28 rotations per minute.

Introduction. Concrete is a construction that is made as infrastructure, so that durability is a thing that is strongly influenced by work methods (Uysal et al., 2019), as well as the ability of concrete to withstand the durability of steel in order to prevent corrosion is very limited and requires long research (Uysal et al., 2019).Very diverse people in the process of making concrete

Relation Between Compressive and Tensile Strength of Concrete

Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the water-cement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more. Commercial production of concrete with ordinary

How much concrete in a RMC truck | Concrete truck capacity

In general a TM or RMC truck can hold 6m3 of concrete which is equal to 212 cubic feet (cft) or 2.12 brass or approximately equal as 14.4 MT. However during the placement of that concrete at site the quantity might be a bit less due to transportation loss, evaporation losses, improper placement at site and for poor labour efficiency.
