This dataset represents the production of South African 45MPa ready-mix concrete. Density: 2,260 kg/m³. The composition of concrete (for 1 m³) contains: Portland fly ash cement 464 kg, Water 147 kg, Gravel 1050kg, Sand 746 kg, Admixtures (air-entrainers and superplastisizers) 4.63kg.
[The amount of ingredients indicated here do not include the production waste amount of 24.5kg per 1m3 of concrete adopted from "concrete production, 50MPa, RNA only, GLO 2006" dataset [accessed on 2017/12/14 ]. The production waste volume is proportionally shared between the inputs: cement, sand and gravel. The adjusted input values are indicated in the exchange section. In addition, the amount of water included here refers to the batch water. Non-process water is adopted from "concrete production, 50MPa, RNA only, GLO 2006" dataset [accessed on 2017/12/14 ]]. 45 MPa concrete is High-strength concrete should be used for suspended structural beams and slabs, and pre-cast items such as flagstones and heavy-duty floors such as workshop floors.
Annual production volume of Ready-Mix concrete for South Africa is published in www.statssa.gov.za.
Distribution by Ready-Mix concrete for South Africa is estimated based on a sample of 1% of ready-mix producers in SA. Distribution by ready-mix strength class is estimate as: • 15MPa = 3.6% 20 MPa = 4 %
• 25 MPa = 32 %
• 30 MPa = 49%
• 35 MPa = 4 %
• 40 MPa = 6 %
• 45 MPa = 0.1 %
• 50 MPa = 1.3%

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
