When utilizing this dataset for Life Cycle Assessment of Portland-composite cement, it's crucial to adhere to the defined system boundaries which include the transportation and grinding of granulated blast furnace slag and fly ash, as well as the mining and transportation of limestone, iron ore, clay, gypsum, and coal. Processes like electricity production for the manufacturing should be considered in the impact assessment. The dataset should be applied assuming the recycling and energy recovery aspects are excluded. Ensure that the addition ratios for clinker and gypsum are at 60% and 5% of the cement mass respectively, as per the GB-175-2007 standard when applying material data to ensure accuracy and consistency.
Data set use approval
General comment
Use the new dry cement production technology as the technical object.The main raw materials required for portland-composite cement production include limestone, clay, iron powder, gypsum, granulated blast furnace slag and fly ash. During the production process, granulated blast furnace slag and fly ash are added to the cement instead of clinker.

Technical purpose
Portland-composite cement production using the new dry process applies predominantly to the construction industry. This cement variant is specifically designed for general construction purposes such as the building of structures, pavements, foundations, and is suitable for both reinforced concrete and pre-stressed concrete. The incorporation of granulated blast furnace slag and fly ash as partial substitutes for clinker not only optimizes the use of by-products from other industrial processes but also contributes to the reduction of CO2 emissions and energy consumption in the cement industry.
