Stone offcuts have so many uses(1)

For stone processing plants, the daily processing of stone generates a large amount of waste, including scraps, chips, and sludge. If these waste materials are simply disposed of through landfill, it will not only occupy a large amount of land resources but also severely damage the ecological environment and disrupt the food chain balance near the landfill site, causing profound and irreparable damage to the local area.

 

In fact, these stone waste materials are excellent raw materials themselves. Through various comprehensive utilization projects, they can be fully reintegrated into our lives and put to good use.

Today, let's take a look at the various ways to transform stone waste into valuable resources.

Mosaic is a very ancient decorative technique. Its principle is to create unique artistic patterns by cutting and assembling stones of different textures and colors. Through mosaic work, different types of floor tiles can be integrated, resulting in a richer and more layered visual effect compared to a single decorative style.

With the advancement of modern design and manufacturing technologies, this technique is experiencing a resurgence. Currently, many projects in hotels, restaurants, shopping malls, and airports in China are using mosaics to enhance their decorative effects. This has led to an increase in the quantity and variety of stone mosaics used, and the patterns are becoming increasingly complex. The leftover scraps from stone processing are an excellent source of material for stone mosaics. Marble, granite, and various artificial stones can all be utilized.

 

Processing these leftover stone scraps for use in seamless mosaic techniques, jointed mosaic techniques, waterjet cutting mosaics, and handmade mosaics not only makes full use of waste resources, achieving environmentally friendly and economical results, but also allows the beauty of the stone and the exquisite patterns to fill the entire environment with warmth and vitality.

 

 

 

 

 

In the early 20th century, the use of steel structures led to a decrease in the use of stone as a load-bearing material, and stone gradually became a surface decorative material for buildings. After the 1940s, steel structures were replaced by concrete buildings, and this shift resulted in a continuous reduction in the thickness of stone used for decorative surfaces. Consequently, stone cladding has become a popular method of using stone in modern architecture.

 

Stone cladding, as the name suggests, refers to a wall treatment method where stone is attached to wall and column surfaces using adhesive or mechanical fastening techniques, serving both decorative and protective purposes. In fact, it's not only large stone slabs that can be used for cladding; small scraps and offcuts from stone processing also have their uses.

 

In interior decoration, stone offcuts can be cut into small tiles of various shapes and used for cladding in smaller areas such as corridors, balconies, and bathrooms, providing durability, cleanliness, and a neat and aesthetically pleasing appearance. In exterior decoration, stone offcuts can be processed according to actual needs and used for paving roads, walls, and sidewalks, or combined with different colors to create various vivid patterns, making the outdoor environment more interesting.

 

Besides cladding, directly stacking stone around the main building structure can often achieve unexpectedly good results.

 

 

 

 

Numerous practical studies have shown that using waste stone powder, such as granite powder, at a dosage of less than 10% as a concrete admixture to replace cement helps increase the paste content of concrete. This not only improves the workability and slump of the concrete mixture and reduces bleeding, thus improving concrete performance and meeting concrete performance requirements, but also reduces concrete production costs, reduces environmental pollution, promotes the development of a circular economy, and improves resource utilization efficiency.

 

 

 

Autoclaved aerated concrete blocks are a new type of building material that is lightweight and porous, possessing characteristics such as light weight, high strength, heat insulation, sound absorption, fire resistance, and machinability (sawing and planing). Its typical density is 500-700 kg/m³, which is only 1/4-1/3 of clay bricks and sand-lime bricks, and 1/5 of ordinary concrete, making it one of the lightest types of concrete. It is suitable for infill walls in high-rise buildings and load-bearing walls in low-rise buildings. Using this material can reduce the self-weight of the entire building by more than 40% compared to ordinary brick-concrete structures. Because the building's self-weight is reduced, the seismic damage is less, thus greatly improving the building's earthquake resistance.

The main raw materials for making autoclaved aerated concrete blocks include lime, fly ash, slag, gypsum, cement, sand, foaming agents, bubble stabilizers, and regulators.

 

 

Autoclaved sand-lime bricks are made from sand and lime as the main raw materials, with the addition of pigments and admixtures. They are produced through raw material preparation, pressing and molding, and high-pressure steam curing. This is a mature, high-performance, and energy-efficient new building material, suitable for load-bearing walls in multi-story mixed-structure buildings.

 

Industry tests have shown that with appropriate technical measures, autoclaved sand-lime bricks with a strength grade of 15 or higher can be produced using granite powder waste from stone processing plants. Utilizing this powder waste to manufacture autoclaved sand-lime bricks is undoubtedly an economical and effective method to address environmental pollution in the stone industry. It not only offers good economic benefits but also has profound social significance in terms of energy conservation, environmental protection, and resource recycling.
