Abstract

The invention discloses high-titanium blast furnace slag pervious concrete and a using method thereof. The high-titanium blast furnace slag pervious concrete is prepared from, by mass, 1330-1360 partsof high-titanium blast furnace slag particles, 120-150 parts of high-titanium blast furnace water-quenched slag, 210-240 parts of cement, 9-11 parts of superplasticizer, 12-13 parts of enhancer, 13-15 parts of pigment and 90-95 parts of water. The preparation method comprises the following steps: uniformly mixing and stirring the raw materials, conducting paving and rolling on the ground, and naturally conducting curing for 12-15 days. According to the method, the utilization amount of waste resource blast furnace slag in the metallurgical process is effectively increased, and the productioncost is reduced.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-titanium type blast furnace slag permeable concrete and a use method thereof. Background technique [0002] Permeable concrete is mainly used for non-heavy-loaded pavements such as sidewalks and squares. Because of its good water permeability, it has the effects of sound absorption and noise reduction, flood resistance, water accumulation prevention, surface temperature reduction, and groundwater table beautification and ecological environment improvement. . Because ordinary permeable concrete aggregates are mainly made of solid natural stone, which has caused certain damage to the natural ecological environment, its development and application have been limited to a certain extent. [0003] High-titanium blast furnace slag expanded beads are a new type of material developed to solve the multi-utilization of blast furnace slag. The scope of application has be...
