Included activities starts

The activity starts with the production and import of "wet mix mortar" in the region.

Included activities ends

The activity ends with the supply of "wet mix mortar" to the consumers of the product. Transportation is included; the loss of the product during transportation is negligible and therefore is excluded.

Description

This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. This dataset represents the average resource consumption and environmental emissions of wet-mixed mortar production in China. The dataset considers the raw and auxiliary materials (such as cement, aggregate, stone powder/fly ash, admixtures), energy, and related emissions and process waste in the core manufacturing processes such as material storage, sand drying and screening, and mixing, as well as the auxiliary processes such as related waste treatment. It does not include product packaging, downstream transport, production equipment manufacturing, plant and other infrastructure construction; the inventory has been supplemented and improved according to the material balance and water balance. The data is mainly sourced from industry technical materials and publicly available enterprise production materials, etc.

Activity Description

The system boundary covers core manufacturing processes such as material storage, sand baking, screening, mixing and blending, as well as related auxiliary processes such as waste treatment, excluding product packaging.

Process Description

Wet-mix mortar is a mixture made of cement, fine aggregate, mineral admixtures, admixtures and water in a certain proportion, measured and mixed in a professional production plant and used within a specified time. The apparent density is 1900 kg/m3.
