Environment-friendly cement brick and manufacturing process thereof

The invention discloses an environment-friendly cement brick and a manufacturing process thereof. The environment-friendly cement brick comprises a brick body, and the brick body is composed of the following components in parts by weight: 20-80 parts of cement; 30-50 parts of fly ash; 10-20 parts of quick lime; 80-100 parts of aggregate; 20-30 parts of mirabilite; 5-10 parts of ceramsite; and 1-5parts of an assistant. According to the present invention, the ratio is reasonable, such that the prepared cement brick has characteristics of high strength, high bearing capacity, good compression resistance and good shock resistance, and the mass of the brick body is substantially reduced so as to make the cement brick have advantages of light weight and high strength, and the production processof the environment-friendly cement brick comprises the following steps: premixing, secondary mixing, compression molding and drying, the manufacturing process is simple, the process continuity is good, the cement brick manufa
