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 permeable concrete and its preparation method and construction process, wherein the reinforcing agent comprises the following components in parts by weight: 50-80 parts of nano-scale silicon powder, 10-15 parts of water reducer, 2~4 parts of cellulose, 8~10 parts of calcium sulfate whiskers, 5~8 parts of trisodium phosphate, 1.5~5 parts of calcium carboxylate, 2~6 parts of alkali metal carbonate and 0.5~2 parts of formamide. The reinforcing agent can improve the bonding effect of cement, improve the compressive strength and service life of the permeable concrete pavement at the same time, and can also simplify the construction process, the process flow is short and the project progress is fast, and has significant economic and social benefits.

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...
