Innovations in micro Concrete: origins and modern uses
Micro concrete is much more than just a finishing material. Born of an aesthetic quest in the 1970s, it has become an essential decorative solution, combining design and durability. Thanks to innovations in micro concrete by major players such as Marius Aurenti, this material has undergone a remarkable evolution, from a simple craft technique to a trend favored by architects and designers.
Whether for residential, commercial or exterior projects, micro concrete seduces with its versatility, modern finishes and wide range of applications. Discover the history, innovations and contemporary uses of this emblematic material.
Origin and evolution of the term "micro concrete
Historically, concrete was a structural material used for floors, slabs and other load-bearing elements. In the 1970s and 1980s, finishing techniques were developed to improve the aesthetics of concrete surfaces, notably through the application of hot or cold concrete. The aim of these methods was to provide a glossy finish and protect concrete from external aggression.
The term ” micro concrete” was coined to designate those concrete surfaces treated with wax. However, it has become a generic term encompassing a variety of finishing techniques and materials, often far removed from the original method.
Concrete vs. mortar: an essential distinction
It’s important to distinguish concrete from mortar. Concrete is composed of cement, sand, gravel and water, and is mainly used for load-bearing structures. Mortar, on the other hand, is a mixture of cement, sand and water, without gravel, used for finishing or bonding applications.
In the context of “micro concrete”, these are actually millimetric mortars, i.e. fine coatings applied in layers of just a few millimeters. These mortars are formulated with fine aggregates and specific additives to deliver a smooth, aesthetic finish.
Marius Aurenti's contribution to the development of micro concrete
Marius Aurenti, a pioneer in the field of decorative coatings, played a key role in the evolution of “micro concrete” and its innovations. In the 1980s, the company developed specific formulations of millimetric mortars, suitable for decorative applications on a variety of surfaces.
At the same time, Marius Aurenti developed protection systems for these coatings, inspired by techniques used to protect walls in urban environments against graffiti. These systems, based on polyurethane varnishes, have improved the durability and resistance of treated surfaces, while facilitating their maintenance.
From wax to varnish: an evolution in protection techniques
While early applications of micro concrete used waxed for finishing and protection, practices have evolved towards the use of varnishes. Varnishes, especially polyurethane-based ones, offer superior protection against wear, stains and chemical aggression. They form a durable protective layer, while preserving the aesthetics of the substrate.
Today, in the majority of cases, micro concrete surfaces are protected by varnishes. However, for ecological projects or specific applications, the use of natural waxes remains a preferred option. These waxes offer an authentic matte finish, while respecting the environment.
Contemporary applications of micro concrete
Micro concrete” is appreciated for its versatility and modern aesthetic. It is used in a variety of contexts, such as :
–Residential interiors: floors, walls, worktops, bathrooms.
–Commercial spaces: restaurants, hotels, boutiques.
–Exterior fittings: terraces, facades, street furniture.
Its ability to adapt to different substrates and offer a wide range of colors and textures makes it a popular choice for architects and designers.
The term micro concrete has evolved since its inception, from a specific finishing technique to a name encompassing a variety of decorative methods and materials. Thanks to the innovations of waxed concrete and pioneers like Marius Aurenti, waxed concrete has become an essential element of contemporary decoration, combining aesthetics and functionality.
