Scope

Scope: This document specifies the raw materials and mix ratios, technical requirements, testing methods, inspection rules, and requirements for ordering and delivery of composite solidified soil. This document is applicable to the base fill of port roads and storage yards. Main technical content: 4.2.1 Alkali slag 4.2.1.1 Alkali slag is mainly derived from the waste residue discharged during the production of soda ash by the ammonia-alkali process. Before comprehensive utilization, the characteristics of hazardous waste should be identified and dangerous waste should be eliminated, and it should be comprehensively utilized in accordance with the environmental management requirements of its properties. 4.2.1.2 The maximum particle size of alkali slag should not exceed 300mm. 4.2.2 Mineral powder 4.2.2.1 Mineral powder is mainly derived from the industrial solid waste obtained by quenching and grinding the melted material obtained during the smelting of pig iron in a blast furnace. 4.2.2.2 When mineral powder is used as a solidifying material, the active components and their content, specific surface area, particle size distribution, and sulfide content should be determined. 4.2.2.3 Mineral powder should be selected in accordance with the technical requirements of GB/T 18046, and the grade should not be lower than S95. 4.2.3 Fly ash 4.2.3.1 Fly ash is mainly derived from the by-product of coal-fired power generation. 4.2.3.2 When fly ash is used as a solidifying material, the active components and their content, specific surface area, particle size distribution, and the types and content of heavy metals should be determined. 4.2.3.3 Fly ash should comply with the requirements of GB/T 1596, and the grade should not be lower than II. 4.3 Catalysts 4.3.1 Catalysts play a role in activating the solidifying materials. Different types of catalysts should be used for different solidifying materials, and the catalyst composition should not cont
