Abstract
The invention is a sand-free macroporous regenerative concrete mixture and its preparing method, using the regenerative aggregate made by crushing discarded concrete, as main raw material, adding in cement and water to make it. The mixture has large porosity, higher intensity, strong water permeability, good deformation resisting ability and other characters, and it is a relatively ideal construction material for slopes and road surfaces greening and protecting landscape, able to be widely applied to construction of bank slopes of riverway, city greening, etc.
Description
Technical field
The invention belongs to the concrete material technical field, being specifically related to a kind of regenerated aggregate that is broken into discarded concrete etc. is the sand-free coarse porous concrete crack concrete material and the preparation method of main raw material.
Background technology
On the one hand, growing along with the quick propelling of Urbanization in China and town development, the reconstruction of the old city town engineering is increasing.Owing to reasons such as municipal administration resettlement, road enlarging, accident dismounting and transformation reinforcings, produced a large amount of discarded concretes.These discarded concretes have had a strong impact on the Sustainable development of urban ecology and environment.
On the other hand, Eco-city construction and environment protection, need to reduce as far as possible exposed soil () face; The bank protection of the improvement in river and road and railway needs a large amount of concrete.These concrete have reduced and can afforest land area when finishing bank protection and strengthening the dikes, reduce exposed ground, and cause significantly " tropical island effect " in the city.
The concrete invention in sand-free coarse porous concrete crack can reduce the exploitation to natural sand in a large amount of recycling discarded concretes, improve greening efficient and reduce city " tropical island effect ".
Summary of the invention
The objective of the invention is to propose a kind of regeneration concrete compound and preparation method thereof with high porosity and higher-strength.
The sand-free coarse porous concrete crack regeneration concrete compound that the present invention proposes, the reclaimed concrete aggregate that is broken into cement and discarded concrete is a main component, adds the water stirring and forms, its prescription by quality is as follows:
Cement: 2-20%
Water: 2-20%
Reclaimed concrete aggregate: 60-85%
Above material is calculated its summation by mass percentage should satisfy 100%.
Above-mentioned regeneration concrete compound, the prescription that each component is comparatively suitable is:
Cement: 5-20%
Water: 5-15%
Reclaimed concrete aggregate: 70%-85%
Its total amount satisfies 100%.
Wherein each being formed divides the quality requirements of material as follows:
Cement: ordinary Portland cement, road cement, grade 32.5 or 42.5 is advisable.
Reclaimed concrete aggregate: the size distribution of reclaimed concrete aggregate is between 5-80mm, and wherein silt content must be less than 5%.
In the above-mentioned reclaimed concrete aggregate, preferably can dispose by following size distribution: that 5-10mm is 10-40%, and that 15-40mm is 40-70%, and that 50-80mm is 15-40%.
The preparation process of regeneration concrete compound of the present invention is as follows:
Take by weighing the each component material by mass ratio cement and reclaimed concrete aggregate are poured in the stirrer, add water and stir, water and smash after the moulding maintenance 25-30 days.
The present invention utilizes activity of cement effect, and the regenerated aggregate that is broken into discarded concrete is that main raw material is made.This compound has characteristics such as porosity is big, intensity is higher, water-permeable is strong, non-deformability is good, be a kind of more satisfactory greening and view bank protection and pavement construction material, can be widely used in the construction of river course bank slope, urban afforestation and modern agriculture greenhouse and nursery terrace etc.
The present invention has the following advantages:
1) adopt this kind type material to make the greening surface layer after, can increase rainwater under thoroughly, reduce city " tropical island effect "; Also can improve in the soil on the moisture thoroughly, improve the possibility that vegetation survives and grows.
2) to adopt discarded concrete be main raw material in the present invention, can reclaim in a large number and efficiently utilize scrap feed material, also can save the land seizure amount in a large number.
3) adopt this kind mode to cooperate, can strengthen the dikes, the greening river course improves security.
4) make full use of discarded concrete, reduce exploitation, have tangible environment, economy and social synthesis's benefit natural sandstone.
