Understanding Volumetric Concrete Mixers
Concrete is a vital aspect of any construction project. Whether it involves support formation for tonnes of weight through reinforced beams or designing building footings, this material is present almost everywhere in the world of construction.
This material has been around since ancient Roman times, and there have been hundreds of technological advancements in its preparation methods over the centuries. One of the most recent and useful ones is undoubtedly the invention of the volumetric concrete mixer, an essential piece of equipment found at several job sites. Let’s take a brief look at its origin, operation, and benefits.
The Origin & Principles of Volumetric Mixers
This form of equipment was first built around the ‘60s when the need to deliver fresh concrete to construction sites was perceived. The first patent for a mobile mixer was obtained in 1964, giving the right to a single manufacturer for the better part of two decades.
The reason volumetric mixers were created was to overcome the challenge most commonly faced with pouring concrete- that is, to provide different formulations to fulfill different requirements and applications as quickly as possible. For instance, a road would require a concrete mixture with different constituent proportions than those needed by the load-bearing beams of a high-rise.
A mixer is equipped on a truck to simplify concrete transportation between locations. However, an important thing to note here is that the mixer contains all the constituents, such as cement, sand, stone, and water in separate chambers rather than as a pre-mixed combination.
This makes it much more convenient to mix the exact proportion and quantity of concrete required for a specific application. The use of volumetric concrete mixers also boosts on-site efficiency while decreasing the expenses involved in transporting concrete.
Advantages of Volumetric Concrete Mixers
The major advantage of using a volumetric concrete mixer is having the ability to produce exceedingly precise formulations while ensuring excellent quality on-site. Additional benefits include:
- Freshly prepared concrete with each load able to give variable mixes
- Minimized wastage
- Decreased operational expenses
- Improved capacity
- Increased efficiency and production rates
- Greater control over concrete preparation
- Better ability to accommodate varying load sizes
These are the reasons why volumetric concrete mixer trucks have been in significant use across the entire construction landscape. After all, there is no denying their importance in today’s fast-paced world, especially where contractors must work out precise amounts of concrete required for each project.
