Ⅰ. Sulphoaluminate cement is used in garden landscape

With the improvement of science and technology, garden landscape has become a part of people's enjoyment. With the development of economy and society, plastic rockery with sulphoaluminate cement as raw material is replacing the rockery with ordinary cement as raw material. Because sulphoaluminate cement has early strength, high strength, anti-freezing, impermeability, corrosion resistance and It has excellent characteristics such as low alkalinity, and saves a lot of manpower and material resources in terms of cost and flexibility, and truly achieves the effects of low carbon, ecology and environmental protection.

Ⅱ. Advantages of sulphoaluminate cement

The main mineral components of sulphoaluminate cement and Portland cement are different. Sulphoaluminate cement clinker minerals are mainly anhydrous calcium sulfoaluminate (3CaO·3Al2O3·CaSO4), dicalcium silicate (2CaO·SiO2) and Iron phase (2CaO·Fe2O3-6CaO·2Al2O3·Fe2O3). Anhydrous calcium sulfoaluminate has high hydration activity, can quickly hydrate and produce a certain volume expansion. Sulphoaluminate cement has many special properties that Portland cement does not have. The main characteristics are as follows:

1. It has remarkable characteristics of energy saving and emission reduction. Compared with Portland cement, sulphoaluminate cement has about 20% lower limestone content and a sintering temperature of about 150°C lower. It has the characteristics of low carbon emissions and low energy consumption, which is of great importance to the country's energy conservation and emission reduction. Meaning.

2.It has the characteristics of efficient utilization of industrial waste residue. Modified sulphoaluminate cement raw materials can use industrial waste residues containing CaO, Al2O3, SiO2, SO3, Fe2O3 and other chemical components, such as fly ash, coal gangue, red mud, industrial gypsum, etc. instead of natural raw materials, which can be effectively absorbed It is of great significance to solve the problems of industrial wastes occupying land resources, polluting the environment, and causing safety hazards, and it is in line with the policy of vigorously developing circular economy.
