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
The invention belongs to road construction material and preparation thereof, relate to a kind of from permeable lightweight binding material and preparation side thereof
Method.The present invention is particularly useful as the urban water-through using permeable pavement brick, porous pavement plate to mat formation from permeable lightweight binding material
Road, the bonding screed-coat on square.
Background technology
For effectively solving modern city waterlogging, overland flow pollutes degradation problem under waste, level of ground water, and country proposes to build
If sponge Urban strategy.In November, 2014, state lives the portion of building and puts into effect " sponge urban construction technical manual ", talks about sponge in guide
City should follow " ooze, stagnant, store, clean, with, row " six word policies, water suction, water-retention, infiltration, water purification when i.e. raining, will storage when needing
The water deposited " discharges " and is used.Sponge urban construction is a systemic engineering, needs the organic of each critical component
Combination, permeable road is exactly key components of sponge urban construction.For using permeable pavement brick, road deck to mat formation
Permeable road such as light-duty load road, parking lot and square and footpath, shopping mall etc., its structure sheaf generally comprises surface layer, viscous
Knot screed-coat, basic unit and underlayment (seeing accompanying drawing 1).
In prior art, water-permeable brick surface layer mainly uses concrete permeable brick, permeable stone, sintering brick permeable to water etc. to mat formation；Base
Layer uses the casts in situs such as rubble, pervious concrete, pervious cement stabilization gravel or rolls；Underlayment need to be according to local geology
Situation is designed.For ensureing water-permeable brick smooth degree of layer, steadiness and the caking property with basic unit thereof, need at water-permeable brick surface layer
And bonding screed-coat is set between basic unit.At present, bonding screed-coat mainly uses medium sand, coarse sand or dry cement mortar paving
Dress.In general, permeable road deck, basic unit, underlayment material therefor are the most ripe, below the screed-coat that bonds then exists
Problem:
(1) directly using the bonding screed-coat that medium sand, coarse sand are mated formation, water permeability is good, but lacks self-adhesive, fixing energy
Power, later stage bulk sand easily infiltrates into basic unit or along with rain water runoff, causes surface layer steadiness and flatness to decline to a great extent；
(2) dry cement mortar has the levelling performance that preferably bonds, but along with hydrated cementitious, consolidation known from experience by cement mortar
In aggregate space, block water-permeable passage, cause bonding screed-coat water permeable ability to decline to a great extent.
Visible, as permeable road deck and the important node of basic unit, permeable, bonding, the levelling performance of bonding screed-coat
Directly affect water permeability and the steadiness of whole permeable road.And bonding taken into account by traditional permeable road bonding screed-coat material
All there is bigger defect in property and water penetration aspect.
