Embodiment 1
[0037] According to the formula in Table 1, each raw material was quantitatively weighed, first poured into the pouring pool 1846kg of machine-made sand and weathered sand mixture, 65kg of gypsum and 1150kg of surface water, stirred evenly to form a mortar slurry, and then poured in 343kg of lime, 321kg of cement and the rest Mix water in a certain amount, stir for a certain time, control the slurry temperature, when the temperature is ≥35°C, add water-based aluminum powder paste (0.91kg as aluminum) and air-entraining agent water (0.25kg as saponin) to form Stir for a certain amount of time to control the expansion degree of the slurry. When the expansion degree is ≥ 30cm, the inner volume of the slurry injection is 3.24m 3 After the pouring is completed, the mold is moved to the static parking room for maintenance for a certain period of time. After the green body meets the solidification requirements, it is moved out of the static parking room. After cutting and forming acco...
Embodiment 2
[0040] According to the formula in Table 1, each raw material was quantitatively weighed, first poured into the pouring pool 1861kg of river sand, 64kg of gypsum and 1150kg of river water, stirred evenly to form a mortar slurry, then poured into 332kg of lime, 331kg of cement and the rest of mixing water, Stir for a certain time to control the temperature of the slurry. When the temperature is ≥35°C, pour 0.92kg of aluminum powder and air-entraining agent powder (0.23kg in terms of saponin) directly, and stir for a certain time to control the expansion of the slurry. The expansion is ≥ At 30cm, the inner volume of slurry injection is 3.24m 3 After the pouring is completed, the mold is moved to the static parking room for maintenance for a certain period of time. After the green body meets the solidification requirements, it is moved out of the static parking room. After cutting and forming according to the product specifications, the mold is freed, and the green body is moved t...
Embodiment 3
[0043] According to the formula in Table 1, each raw material was quantitatively weighed, and 1875kg of sea sand, 63kg of gypsum and 1150kg of seawater were first poured into the pouring pool, and stirred to form a mortar slurry, and then 325kg of lime, 341kg of cement and the rest of mixing water were poured in. Stir for a certain time and control the slurry temperature. When the temperature is ≥35°C, add water-based aluminum powder paste (0.93kg as aluminum), air-entraining agent powder (0.21kg as saponin) and 1.8kg of water. Suspension, stir for some time to control the degree of expansion of the slurry, when the degree of expansion is ≥ 30cm, the inner volume of the slurry injection is 3.24m 3 After the pouring is completed, the mold is moved to the static parking room for maintenance for a certain period of time. After the green body meets the solidification requirements, it is moved out of the static parking room. After cutting and forming according to the product specifi...
