Abstract
The invention relates to a recycled-aggregate heat-preservation building block material which is made into building blocks according to a known technology and comprises the following materials according to mass percentage: 11%-13% of water, 42%-45% of coarse aggregate, 23%-26% of fine aggregate, 19%-21% of cementing materials and 2%-3% of heat preservation materials (namely glass beads). The building block is energy-saving, high in strength, capable of bearing load, good in thermal performance, economical, good in durability, beneficial to waste utilization, and environment-friendly, and is made from the green recycled-aggregate heat-preservation building block material provided by the invention.
Description
Technical field
The present invention relates to a kind of blockwork material, particularly a kind of body of wall regeneration aggregate heat insulation block material.
Background technology
In recent years, the renewal of Urban House and municipal moving scale continue to increase, a large amount of old buildings are demolished, or because natural disaster occuring, make the urban architecture quantity of refuse increasing, reclaim resource and environmental contamination reduction in order rationally to utilize, research and the application of building castoff recycling become a kind of new trend.Simultaneously along with social progress and development, the requirement of building structure function and material of construction performance is also all being changed, from the basic role of initial simple " safeguarding and load-bearing " to insulation, the multifunctional directions such as energy-conservation, heat insulation, antidetonation, green develop.
At present, the ubiquitous problem of China's building energy conservation and environment protection: the one, thermal and insulating performance is poor, and production and Energy in use are apparently higher than developed countries; The 2nd, the recrementitious environmental pollution of various industrial residues and urban architecture is also quite serious.If can take full advantage of these existing rejected materials, and consider to add some materials that can improve some function of material and produce some building material products, also utilize various waste materials when alleviating environmental pollution, also play a role in energy saving when saving stacking land used reduction cost, can accomplish fully " achieving many things at one stroke ".
Now concrete bearing and non-bearing building block be with cement, sand, and stone and slag are main raw material, heat preservation and insulation is poor, simultaneously a large amount of consumption natural resource, cost is high, is difficult to satisfy energy-conservation and environmental protection to the requirement of materials for wall.And the at present development of Building technology has all proposed higher requirement to construction material from material property itself and materials'use function, i.e. composite type energy-saving, environment-friendly building materials more than excellent, the function of performance satisfy the green building of future development.
Summary of the invention
The technical problem to be solved in the present invention be for present walling unit with cement, sand, stone and slag are main raw material, heat preservation and insulation is poor, a large amount of consumption natural resource simultaneously, cost is high, is difficult to satisfy energy-conservation and environmental protection to the requirement of materials for wall, the invention provides a kind of energy-conservation, high-strength, thermal property is good, economy, good endurance, not only a kind of green regenerating aggregate heat insulation block material of sharp useless but also environmental protection.
For addressing the above problem, the present invention adopts following technical scheme to implement:
A kind of regeneration aggregate insulation blocks, this block material is comprised of the raw material of following weight percent:
Water: 11% ~ 13%;
Coarse aggregate: the natural rubble of particle size range 5 ~ 20mm and particle diameter are the regenerated coarse aggregate 41% ~ 45% of 5 ~ 10mm, wherein regenerated coarse aggregate replacement rate 30% ~ 50%;
Fine aggregate: the natural sand of fineness modulus 2.3 and particle size range 0.15 ~ 4.75mm recycled fine aggregate 22% ~ 26%, wherein recycled fine aggregate replacement rate 20% ~ 30%;
Gelling material: 19% ~ 21%;
Lagging material: 2% ~ 3%.
As to of the present invention preferred, lagging material of the present invention is glass bead; Described gelling material is the mixture of cement and flyash or the mixture of cement and slag, and wherein flyash or slag 30% equivalent replace cement.
According to the above ratio, adopt the secondary stirring method to mix the water that the type of making adds recycled fine aggregate, natural fine aggregate, lagging material, gelling material and part for the first time, stir 30 ~ 60s; Add for the second time regenerated coarse aggregate, natural coarse aggregate and remaining gelling material, stir 60 ~ 90s, the time can suitably be adjusted flexibly according to different situations.Make the regeneration aggregate insulation blocks of 390mm * 190mm * 190mm after the system of mixing of block machine.
After adopting above-mentioned technical scheme, the present invention has following advantage compared to existing technology:
(1) the present invention is reasonable effectively selects to utilize the regeneration aggregate of discarded concrete fragmentation to come most of replacement natural aggregate and efficient lagging material---glass bead; various materials to preparation carry out scientific optimization; rational Match; make the mixed structure distribution of aggregate, lagging material and consolidating material evenly reasonable; make various materials bring into play cooperative usefulness; reach best intensity, good thermal property and good weather resistance, the finally satisfied national technical indicator that novel wall material is required.
(2) the Main physical mechanical property of building block of the present invention: ultimate compression strength 5MPa; Thermal conductivity 0.263w/m.k; Frost resistance D25 is qualified, and the production power consumption is low, pollution-free, but is a kind of green structural material product of recirculation.
(3) product of the present invention has the characteristics such as high-strength, heat insulating, freeze proof and anti-seismic performance be good; Reduce the usage quantity of natural aggregate, also alleviated built-loading simultaneously, the engineering comprehensive cost reduces.The regeneration aggregate insulation blocks of preparation can be built into separately wall by laying bricks or stones, has solved globality and the weathering resistance of building heat preservation body of wall, makes real the realization and the same life-span of buildings in work-ing life of wall insulation system; Also stopped simultaneously because the disaster hidden-trouble that the independent heat insulating material for external of exterior wall produces; Owing to need not to do again exterior-wall heat insulation, also reduced building cost, save the duration.
