Water washed stone refers to the mixture of cement and aggregate, which is smoothed and quickly dried, and then washed off with water to expose the surface of the aggregate. The aggregate consists of fine stones with various colors, usually used in sizes of 6-9MM. Water washed stone is a decorative method that uses natural river, sea pebbles, or gravel mixed with cement in a certain proportion, spreads it on the base layer, flattens it with a load-bearing tool, and cleans the surface adhesive to expose the original appearance of the stone. It is similar to the popular water brushed stone process in the 1970s and 1980s.
Water washed stone is widely used in indoor decoration and outdoor landscape design due to its various colors and shapes of raw materials, which can decorate various shapes and designs. Some large areas of exterior wall decoration also use water washed stone, exuding a natural and simple feeling. The quality of the washed stone paving project is stable, the stones are evenly distributed, and the flatness and verticality are easily guaranteed. The construction time of the project is shortened, and the construction environment is clean (if special jointing lines are used, wet operations on site can be completely avoided). The design pattern and shape are not limited, material saving, and can effectively reduce engineering costs. It is a construction method worth promoting.
Terrazzo (also known as millstone) is a product that is ground and polished on the surface after mixing crushed stone, glass, quartz stone and other aggregates into cement binder to make concrete products. The grinding stone system that uses inorganic mineral materials such as cement as aggregate binder is called inorganic grinding stone, while the grinding stone system that uses polymer resin materials as aggregate binder is called organic grinding stone (such as epoxy grinding stone). According to the construction process, Terrazzo can be divided into on-site pouring Terrazzo and prefabricated plate Terrazzo floor. Terrazzo is a composite material, and its aggregate can be selected in a variety of ways. Fluorescent stones can be added to achieve the effect of twinkling stars on the ground at night, and metal can be added to achieve the effect of speckled reflection during the day. At the same time, Terrazzo is not only used for indoor decoration, but also widely used in outdoor landscape design.
