Background technique

At present, the most widely used type of cement is Portland cement, which is not widely used in construction projects, concrete road projects, bridge construction projects, etc. Among them, Portland cement is most used in bridge construction projects. Cement is powdery hydraulic inorganic Cementitious material, mixed with water to form a slurry, can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. Cement agglomeration is a common occurrence in the use of cement in bridge construction projects. The problem of cement agglomeration is caused by the pre-hydration of cement. The water of cement hydration is mainly brought in with the admixture and gypsum during grinding. When the temperature of gypsum is above 60°C to 80°C, most of the crystallization will be lost. The reaction products between water and cement particles are ettringite, monosulfide calcium sulfoaluminate hydrate and potassium gypsum. Factors that cause cement agglomeration include: storage temperature, storage time, gypsum content, etc.

Because a lot of agglomerated cement has no chemical changes, most of the agglomerated cement can be recycled. Nowadays, the crushing method of agglomerated cement is artificial. First, the agglomerated cement is manually crushed into small pieces, and then Grind small pieces of cement, and then sieve the ground cement to obtain reused cement.
