Cement is the material most suitable for construction work. Despite its importance, there are still some doubts about its composition and its derivatives.
Let’s take a closer look at this versatile material, with a look at the solutions designed and implemented by Cormidi for transporting cement within a construction site.
Characteristics and function of cement
Cement is a binding material obtained by the addition of different elements worked together. By firing limestone, clay or marl at high temperature, a mixture of silicates and calcium aluminates is obtained, which are ground together with gypsum in such a way as to slow down the setting process.
The resulting powder, mixed with water, develops adhesive properties and becomes an easy-to-model mass: it sets in a few hours and then becomes as rigid as natural stone, able to withstand high pressures.
One of the most common cements in use worldwide is Portland cement. Portland cement, through various additions, makes it possible to obtain different types of cement: there are different classes depending on the strength, compression and speed of setting required. There are 5 main types: Portland cement, Portland cement mix, blast furnace cement, pozzolanic cement and composite cement.
What differentiates cement from concrete?
Doubts are often raised about the composition of cement and concrete. One of the misunderstandings stems from the fact that reinforced concrete is incorrectly referred to as concrete.
What distinguishes one from the other? The difference is undoubtedly the composition:
- – If cement is mixed with water, cement paste is obtained;
- – If the cement paste is mixed with a fine aggregate such as sand, cement mortar is obtained;
- – If aggregates of different sizes (sand, gravel and gravel) are added to the cement paste, concrete is obtained;
- – Finally, reinforced concrete (called reinforced concrete according to the 1971 regulations) is obtained by coupling concrete with a reinforcement consisting of steel bars placed in a suitable position
From this it can be deduced that concrete is a derivative of cement and is obtained by adding water and aggregates.
The use of cement
Cement began to be produced industrially in the mid-19th century and is still one of the most widely used construction materials today. Its flexibility and guaranteed high performance allow it to be used in a variety of construction sectors. As a construction material, cement is widely used for all types of masonry work: houses, bridges, roads, etc.
But how is the cement transported from one point to another on the construction site? The tool that has always been used for this purpose is the construction wheelbarrow. Over the years, however, this machine has seen a number of evolutions, and today there are state-of-the-art tools with high-performance characteristics. These include Cormidi solutions: machines and accessories specifically designed to make operators’ work as easy and simple as possible.
Cormidi tools for cement transport
Today’s professional construction loader has surpassed the classic wheelbarrow in terms of efficiency, agility, speed and versatility: this is the dumper, Cormidi’s flagship tool. The dumper, moves independently without the need to be towed by force: this saves precious energy and time, especially during construction. The elements that are perfectly suited to the transport of concrete, and designed precisely for this purpose, are the PO and POX skips.
These polyethylene skips are integrated into the minidumper and are ideal for transporting cement from one place to another safely and efficiently. Unlike metal skips, which are more difficult to clean and more prone to rusting, the skips designed by Cormidi can be washed easily and are resistant to the elements.
PO and POX boxes are manufactured using rotational moulding. Rotational moulding, or rotomoulding, is a technology for processing thermoplastic materials at low pressure and high temperature. This process is based on the adhesion of plastic materials to hollow rotational moulds and is used to produce hollow bodies that do not require subsequent welding and assembly.
Cement remains the most suitable material as a binder in construction works. The strong point of this compound is its versatility: it takes on different characteristics depending on the elements it is made of, in order to meet a wide range of needs. Cement is transported to the construction site by wheelbarrow: the more advanced and equipped it is, the better it is able to carry out the movements, optimising the work of the operators. The Cormidi dumper, integrated with the PO and POX bodies, represents an innovative, robust and efficient solution for those who want to carry out their movements in the best possible way during the works.
