When you work in the construction industry, it is important to know all about concrete and concrete mixers. In order to make sure that you and your team of employees are communicating on the same level about concrete mixers, make sure to brush up on some concrete mixer key terms. Learn the following important key terms related to concrete mixers: ready-mix concrete, homogeneity, precast concrete, concrete mixer truck, front discharge, and rear discharge.
Ready-mix concrete, also knows as RMC, is a type of concrete that is custom prepared by a factory before it is delivered to the worksite. Ready-mix concrete does not require the use of a mixer.
Homogeneity is an important factor to consider when choosing a concrete mixer. Homogeneity describes how evenly the materials in a concrete mixture are distributed throughout the mixture.
It is necessary to be aware of overvibration, or over vibration, when pouring concrete from a mixer. Overvibration is the term applied to freshly poured concrete that has been overly manipulated or vibrated, causing the ingredients to separate.
Concrete mixer truck, in-transit mixer
A concrete mixer truck, also known as an in-transit mixer, is a convenient option for mixing concrete on site. Concrete mixer trucks are available in a wide variety of sizes and styles, but most employ the use of a rotating drum to mix the concrete.
Front discharge is the term used to describe concrete mix trucks that discharge, or unload, concrete through a chute at the front of the truck. Front discharge trucks offer the operator more control over where to direct the discharge chute.
Rear discharge is a term used to describe concrete mixer trucks that unload concrete from a chute at the rear of the truck. One disadvantage of using a rear discharge mixer as opposed to a front discharge mixer is that a rear discharge mixer requires a chuteman to work with the driver to guide the truck.
