Laboratory data. In the phosphogypsum-based ecological cement experiment, the main raw materials include phosphogypsum, fly ash, hydrate lime, cement, and early strength agent.Firstly, phosphogypsum is dried in an oven at 45°C to a constant weight to remove free water from phosphogypsum, and then then the dried phosphogypsum is calcined in a high-temperature electric furnace for a certain period of time. The calcined phosphogypsum is then put into a planetary ball mill for grinding for 6 minutes and screened through a standard sieve with a mesh size of 0.08 mm. At the same time, fly ash and hydrate lime are also sieved through a 0.08 mm sieve and dried in a drying oven. The cement used in the experiment also needs to be dried. After the above raw materials are pre-treated, the ingredients are calculated according to the designed ratio, and the mixed material is ball-milled for 3 minutes to mix evenly. After the mixed material is homogenized for 2-3 hours, it is weighed and poured into a JJ-5 planetary cement mortar mixer for stirring, and then molded into cement test blocks using a ZS-15 cement mortar vibrating table. The molded cement test blocks are placed for 24 hours, demolded, and naturally cured. After a certain age, their strength is tested.磷石膏制备生态水泥。实验室数据。在磷石膏基生态水泥试验中，主要原料主要有以下几种：磷石膏、粉煤灰、消石灰、水泥和早强剂。先将磷石膏放入温度为 45°C烘箱中烘干至恒重以去除磷石膏中的游离自由水，然后将烘干后的磷石膏放到高温电炉中煅烧一定的时间。将煅烧好的磷石膏放入行星式球磨机中球磨 6min，随后将球磨好的磷石膏过 0.08mm 的标准筛。在准备磷石膏的同时，粉煤灰和消石灰也过 0.08mm 的筛子，然后放入干燥箱中烘干。实验中所用的水泥也需要烘干。上述原料预处理完毕后，通过设计好的配比计算配料，然后再将配好的混合料在球磨机中球磨 3min 来混合均匀。混合均匀后的混合料均化 2-3 小时后，称量倒入 JJ-5 型行星式水泥胶砂搅拌机进行搅拌，用 ZS-15 型水泥胶砂振实台振动成型，成型好的水泥试块放置 24h 后脱模，自然养护，达到一定的龄期后进行强度检测。8First put the phosphogypsum in an oven at a temperature of 45°C and dry it to a constant weight to remove free water in the phosphogypsum. Then put the dried phosphogypsum into a high-temperature electric furnace and calcine it for a certain period of time. Put the calcined phosphogypsum into a planetary ball mill and ball mill for 6 minutes, and then pass the ball-milled phosphogypsum through a 0.08mm standard sieve. While preparing phosphogypsum, fly ash and slaked lime are also passed through a 0.08mm sieve and then placed in a drying box for drying. The cement used in the experiment also needs to be dried. After the above raw materials are pretreated, the ingredients are calculated according to the designed ratio, and then the prepared mixture is ball milled in a ball mill for 3 minutes to mix evenly. After the homogenized mixture is homogenized for 2-3 hours, weigh it and pour it into the JJ-5 planetary cement mortar mixer for mixing. Use the ZS-15 cement mortar vibrating table to vibrate and shape the formed cement. After the block is placed for 24 hours, it is demoulded and naturally cured.

This dataset represents laboratory-scale preparation of phosphogypsum-based ecological cement and should be used for life cycle assessment (LCA) within the context of research and development. Users should note that the process data is derived from controlled laboratory conditions and may not directly correspond to industrial scale processes. Adjustments to the data may be required when scaling up the process. The dataset includes consideration of raw materials preparation, such as drying and grinding, and the processing stages up to but not including the use phase of the produced cement. Users should ensure that system boundaries are consistent when comparing to other LCA datasets and should incorporate end-of-life considerations if extending the scope of the study beyond storage of the cement.该数据集代表了磷石膏基生态水泥的实验室规模制备，应在研究与开发的背景下用于生命周期评估（LCA）。用户应注意，过程数据来源于受控的实验室条件，并可能不直接对应于工业规模过程。在放大过程时可能需要调整数据。数据集包括原材料准备的考虑，如干燥和磨碎，以及处理阶段直至但不包括所生产水泥的使用阶段。用户应确保在与其他LCA数据集进行比较时系统边界的一致性，并应在研究范围扩展到水泥储存之外时，纳入产品寿命终结的考虑。Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044.清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。Tiangong LCI Data Working Group天工LCI数据工作小组#REF!, ysqsophia@gmail.comysqsophia@gmail.comysqsophia@gmail.com2024-03-19T21:18:09+08:002024-04-20T14:41:09.461655+08:0000.01.005https://lcadata.tiangong.world/showProcess.xhtml?uuid=a72b9bbe-6e50-4d9f-8e95-0df8acc52cd8&version=01.00.000&stock=TianGongTiangong LCI Data Working Group天工LCI数据工作小组falseFree of charge for all users and usesphosphogypsumInput340.0340.0Phosphogypsum.
