Abstract

The invention discloses an engineering paving process for preparing a sponge city water permeable concrete road by using steel slags. The engineering paving process for preparing the sponge city waterpermeable concrete road by using the steel slags comprises the steps of 1, preparing steel lag road-paving blocks; using a crusher to prepare dry steel slags into crushed stone level, sand stone level and ash level steel slag blocks; after raw materials obtained by drying and crushing the steel slags are uniformly mixed with a curing agent, limes, a siliceous additive and water, putting an obtained mixture into a hydraulic machine to be molded, and feeding a molded blank into a hydrothermal reactor to perform hydrothermal curing treatment; 2, laying a water diversion cushion layer; 3, layinga stone cushion layer; 4, laying a lime layer; and 5, laying the steel lag road-paving blocks, laying the steel lag road-paving blocks on the surface of the lime layer and then rolling the steel lag road-paving blocks. According to the engineering paving process for preparing the sponge city water permeable concrete road by using the steel slags, by recycling and reusing the steel slags, the steelslag utilization rate is increased, a purpose of utilizing waste materials is achieved, the pollution and damage of the steel slags to the environment are reduced, and the road paving material cost is reduced.

Description

technical field [0001] The invention relates to a pavement process, in particular to a pavement process for sponge city permeable concrete road engineering made of steel slag. Background technique [0002] A by-product of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, and salts formed by the reaction of these oxides with solvents. A question arises from this, that is, how to deal with the generated steel slag? It is piled up, which will inevitably occupy land; landfill or orogeny will also occupy land; more seriously, steel slag contains a variety of components: 2% to 8% of metallic iron, 40% to 60% of calcium oxide, and 3% to 10% of magnesium oxide , Manganese oxide 1% to 8%. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. A larg...
