Description
This dataset represents the average production situation of high-strength concrete in China. The data are obtained by weighted aggregation of the production datasets of ready-mixed concrete of strength grades C60, C65, C70, C75, C80, C85, C90, C95 and C100, with the aggregation weights estimated from the market share of concrete of each strength grade. The data sources are mainly industry research reports. For the production dataset of ready-mixed concrete of a specific strength grade, its main production raw materials include cement, sand, gravel, water and necessary admixtures. The production processes are mainly the inbound and storage of raw materials, batching and metering, forced mixing and loading/unloading, and the direct environmental emissions in the process mainly involve particulate matter and wastewater. To ensure the representativeness and reliability of the results, some key data have been integrated and supplemented in combination with industry statistical information.
Activity Description
The production system boundary of this product is the entire stage of ready-mixed concrete production, including the arrival and storage of raw materials, batching measurement, forced mixing, etc., including the emission of pollutant gases and dust particles during fuel combustion, and part of the losses are treated as non-recyclable waste.
Process Description
High-strength concrete refers to concrete with a strength grade not less than C60 and belongs to the category of ready-mixed concrete. Strength grades include: C60, C65, C70, C75, C80, C85, C90, C95 and C100. High-strength concrete has high compressive strength, low porosity and excellent deformation resistance, and is widely used in high-rise buildings and long-span structures.

Technology comment
Ready-mixed concrete production adopts precise proportioning and computer automatic control technology. Cement, aggregates, admixtures and water are put into the mixing station according to the designed proportion for centralized mixing. Quality inspection and transportation scheduling systems ensure that the concrete is delivered to the construction site within the specified time and maintains working performance. The entire production process achieves precise measurement of raw materials, automation of the mixing process, and informatization of quality monitoring, ultimately producing uniform and stable concrete products that meet strength requirements.
