Problems solved by technology

[0004] (1) The bonded leveling layer paved directly with medium sand and coarse sand has good water permeability, but lacks self-bonding and fixing capabilities. The loose sand in the later stage is easy to penetrate into the base layer or lose with rainwater, resulting in the stability of the surface layer. The flatness is greatly reduced;
[0005] (2) Dry hard cement mortar has good bonding and leveling performance, but as the cement hydrates, the cement paste will be consolidated in the aggregate voids, blocking the permeable channels, resulting in a significant drop in the water permeability of the bonded leveling layer
However, the traditional permeable road adhesive screed material has great defects in both adhesion and water permeability.

Abstract

The invention discloses a self-permeable light bonding material. The bonding material is characterized by being prepared from the following raw materials in parts by weight through mixing: 224-800 parts of ordinary Portland cement, 0-240 parts of mineral admixtures, 30-45 parts of preformed foam, 3-8 parts of a hole connecting agent and 160-400 parts of water. The preparation method comprises the following steps: the ordinary Portland cement, the mineral admixtures, the hole connecting agent and the preformed foam are evenly mixed, poured and cured naturally, and the self-permeable light bonding material is obtained. When the self-permeable light bonding material is used as a bonding leveling layer of a permeable road in a sponge city, a base layer and a surface layer of the permeable road can be effectively and fixedly bonded; meanwhile, a self-permeation function is realized, so that the bonding property and the permeable property can be combined. The preparation method is simple and easy to implement, a large number of industrial waste residues are used, and the material is applicable to construction of the permeable road in the sponge city and has remarkable economic benefit and broad market prospect.

Description

technical field [0001] The invention belongs to building materials for roads and preparation thereof, and relates to a self-permeable lightweight adhesive material and a preparation method thereof. The self-permeable light-weight bonding material of the invention is particularly suitable for use as a bonding leveling layer for urban permeable roads and squares paved with permeable pavement bricks and permeable road panels. Background technique [0002] In order to effectively solve problems such as waterlogging in modern cities, surface runoff pollution and waste, and groundwater level decline, the state has proposed the strategy of building a sponge city. In November 2014, the Ministry of Housing and Urban-Rural Development issued the "Technical Guidelines for Sponge City Construction", which stated that sponge cities should follow the six-character guideline of "seepage, stagnation, storage, purification, use, and drainage", that is, absorb and store water when it rains ,...
