Problems solved by technology

However, generally speaking, the current production technology of permeable concrete in my country is not yet mature, and the understanding of its water permeability and vegetative properties is still inconsistent, and there is no standard to follow. The existing permeable concrete generally has insufficient strength and weak adhesion. Good, poor water permeability and other problems, especially the exposed aggregate permeable concrete is prone to quality problems such as surface stones shaking or falling off during the subsequent cleaning process

Abstract

The invention discloses a reinforcing agent for previous concrete as well as a preparation method and a construction process of the reinforcing agent. The reinforcing agent is prepared from the following components in parts by weight: 50 to 80 parts of nano-grade silicon powder, 10 to 15 parts of water reducing agent, 2 to 4 parts of cellulose, 8 to 10 parts of calcium sulfate whisker, 5 to 8 parts of trisodium phosphate, 1.5 to 5 parts of calcium carboxylate, 2 to 6 parts of alkali carbonate and 0.5 to 2 parts of formamide. According to the reinforcing agent, the bonding effect of cement canbe enhanced; meanwhile, the compressive strength and service life of a previous concrete pavement are respectively enhanced and prolonged, and the construction process is simplified; the process flowis short, the project progress is quick, and remarkable economic benefit and social benefit are realized.

Description

technical field [0001] The invention relates to a reinforcing agent, a preparation method and a construction process thereof, in particular to a permeable concrete reinforcing agent, a preparation method and a construction process thereof, and belongs to the technical field of sponge city construction. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. use. Sponge city construction should follow the principles of ecological priority, combine natural approaches with artificial measures, and ensure the safety of urban drainage and waterlogging, maximize the accumulation, infiltration and purification of rainwater in urban areas, and promote the utilization of rainwater resources and ecological environment protection. In the process of sponge city construction, the systematic n...
