| 1、混料时间:混料时间长就能混均匀。干混料20分钟比10分钟的强度提高15-23%;湿混料时间以物料不结块为宜。混合好的料存放时间以2小时左右为宜，时间太长或太短，都会降低砖的抗压强度。 1. Mixing time: mixing can be even if mixing time is long. The strength of dry mixed material in 20 minutes is 15-23% higher than that in 10 minutes, and the time of wet mixed material is suitable for the material not to agglomerate. The storage time of the mixed material is about 2 hours. If the time is too long or too short, the compressive strength of the brick will be reduced. 2、成型压力:粘土水泥砖成型时的压力，以每平方厘米500公斤最好。在此压力下，其制品抗压强度高，耐水性能好。压力太低，不易压实。 2. Forming pressure: the best pressure is 500kg / cm2. Under this pressure, the product has high compressive strength and good water resistance. The pressure is too low to compact. 3、养护条件:水泥砖又称免烧砖，成型后再自然环境中淋水养护即可，养护7天龄期的强度，相当于28天龄期强度的67-90%;28天龄期强度为一个季度龄期强度的80-95%。故如养护场地小，水泥砖自然养护7天后就可出厂。 3. Curing conditions: Cement brick is also called unburned brick. After forming, it can be cured by pouring water in the natural environment. The strength of the 7-day curing period is 67-90% of the 28 day curing period, and the strength of the 28 day curing period is 80-95% of the one quarter curing period. Therefore, if the maintenance site is small, the cement brick can leave the factory after 7 days of natural maintenance. |
