Artificial stone, also known as cast stone or reconstructed stone, is a remarkable construction material that has gained significant popularity in recent years. It is engineered by combining cement, sand, and natural aggregates like crushed stone. This composite material can be further enhanced with specific pigments, although the volume of pigments added should not exceed 15% to ensure quality and stability.
One of the most appealing aspects of artificial stone is its versatility in manufacturing. It can be cast into intricate and highly detailed forms, and various sizes can be produced to meet different project requirements. Additionally, it can be reinforced, which effectively increases its strength and durability. The production process of artificial stone is relatively straightforward and cost - effective, making it an attractive option for many applications.
In terms of mix ratio, generally, cement and aggregate are combined in a proportion of 1:3. This ratio provides a good balance between strength and workability, allowing for easy handling during the construction process.
Artificial stone is often chosen for building constructions when cost - effective and durable natural stone is not readily available. Its ability to mimic the appearance of natural stone, combined with its consistent quality and performance, makes it a suitable substitute in many scenarios. For example, in large - scale commercial projects where a uniform look is desired, artificial stone can be used to create a cohesive aesthetic.
There are several types of artificial stones, each with its own unique characteristics and applications. Ransom stone, also called chemical stone, has a compression strength of at least 32 Mpa. It is made by blending silica soda with cement and is commonly used for creating fancy and ornamental flooring. Concrete blocks, another type of artificial stone, are widely used in the construction of steps, window sills, and piers. They can be cast on - site, providing flexibility in construction.
Artificial marble is constructed from Portland gypsum cement and sand, using either precast or cast - in - situ techniques. The precast method involves stripping the casted marble from the mold after three days, treating it with a liquid fluorite of magnesia solution at five days, washing and wrapping it for 24 hours, and then polishing it at 30 days. The in - situ method requires placing a layer of the prepared mixture on a canvas, with a thickness 1.5 mm greater than the desired final thickness. The surface is then rubbed and polished. Bituminous stone is produced by impregnating granite and diorite with refined tar, which gives it excellent wear, noise, and dust - resistance properties.
In conclusion, artificial stone is a versatile and practical construction material. Its wide range of types, ease of production, and various applications make it an important part of the modern construction industry. Whether in residential or commercial projects, artificial stone can offer both aesthetic and functional benefits.
