Problems solved by technology

[0002] The traditional urban concrete pavement blocks the exchange of water and air due to the condensation of mortar, and most of the surface runoff flows into the river through the drainage channel. This not only increases the cost of municipal facilities, but also easily causes flood disasters, and the urban groundwater cannot be well obtained. resupply, land falls, and cities heat up

Abstract

The invention belongs to the technical field of the processing of concrete road plates, and provides an agglomerating agent for a concrete road plate and a preparation method. The agglomerating agent for the concrete road plate is prepared from the following components: 3.1 to 3.5 microns of superfine slag powder, zeolite powder, a water reducing agent, a retardant, magnesium carbonate powder, sodium dodecyl benzene sulfonate, polyisocyanate, furfural acetone resin, cement and a flexibilizer. The polyisocyanate and the furfural acetone resin are added in to the formula of the agglomerating agent, and meanwhile are bound with other components; the manufactured agglomerating agent is enabled to have quite good compression strength and permeability; the performance of the concrete road plate is improved. The preparation method provided by the invention is scientific, reasonable, and simple and is easy to operate. The agglomerating agent is wide in application range and excellent in effect.

Description

technical field [0001] The invention belongs to the technical field of road slab processing, and in particular relates to a gelling agent for concrete road slabs and a preparation method. Background technique [0002] The traditional urban concrete pavement blocks the exchange of water and air due to the condensation of mortar, and most of the surface runoff flows into the river through the drainage channel. This not only increases the cost of municipal facilities, but also easily causes flood disasters, and the urban groundwater cannot be well obtained. The resupply, the ground drops, and the city heats up. Permeable concrete, also known as porous concrete, is characterized by the use of single-grain extremely coarse aggregate as the skeleton, and a thin layer of cement mortar wrapped on the surface of the coarse aggregate particles, which acts as a cementing layer between the aggregate particles to form a skeleton-pore structure. porous concrete material. The key raw mat...
