Abstract
The invention discloses a method for modifying waste and old concreted by filling sugarcane dregs. The sugarcane dreg modified waste and oil concrete is characterized by being composed of the following components in parts by weight: 100 parts of waste and old concrete, 20 to 40 parts of sugarcane dregs, 15 to 25 parts of cement, 0.5 to 2 parts of water reducer, 0.5 to 1.5 parts of magnesium oxide, and 25 to 35 parts of sand; wherein the waste and old concrete is concrete regenerated aggregate, which is prepared through steps of grinding, sorting, screening, cleaning, and drying; the sugarcane dregs are micro powder with a size of 80 to 200 meshes and a water content of 8-10% and are prepared by steps of stacking, fermenting, naturally drying in the sun, bleaching by hydrogen peroxide, and high temperature drying; and the water reducer is a polycarboxylic acid water reducer. The modified concrete can be obtained by the following steps: grinding, drying, and sieving the raw materials mentioned above, then adding the raw materials into a high-speed mixer, and stirring for 20 minutes to obtain the modified concrete. Compared with the prior art, the provided technical scheme has the advantages of economy, environment-friendliness, low cost, and excellent product performance.
Description
Technical field
The invention belongs to building material technical field, particularly relate to the method for the filling-modified waste and old concrete of a kind of bagasse.
Background technology
Along with the continuous propelling of Urbanization Construction, reconstruction of village-in-city, tear open face demolish squatter buildings, the engineering construction paces such as reconstruction of the old city town constantly accelerate, city become more and more beautiful while, building waste generation is but growing with each passing day, and becomes the another large difficult point of environment protection.Building waste bulk deposition, both appropriation of land, also produce surrounding enviroment and have a strong impact on, even bring the trouble in besieged city, if effectively administer not in time, will have endless trouble.But along with the development of science and technology, building waste is regarded as already and has misplaced local resource, but China is slow to the recycling step of building waste, could not form good social benefit.The new features such as over nearly 5 years, the generation of each big city building waste presents enormous amount, the generation cycle concentrates, changing current building waste mainly still takes backfill, landfill and air storage to be main mode, be badly in need of finding new process channel, carry out construction refuse resource process with science, economy, efficient manner.
Summary of the invention
The object of the invention is to: the method that the filling-modified waste and old concrete of a kind of bagasse is provided, adopt bagasse as fibre additive, by rational proportion, reach the object improving concrete performance, reach the object strengthening waste and old concrete physico-chemical property.
To achieve these goals, the present invention adopts following technical scheme:
A method for the filling-modified waste and old concrete of bagasse, is characterized in that: with parts by weight, and the filling-modified waste and old concrete of bagasse is made up of following component:
Further, described waste and old concrete is the regenerative bone material by concrete obtained through broken, sorting, screening, cleaning, drying.
Further, after described bagasse is through heap fermentation, naturally dry, hydrogen peroxide bleaching, hyperthermia drying dewater, the water content of gained is 80 ~ 200 object micro mists of 8 ~ 10%.
Further, described water reducer is polycarboxylate water-reducer.
Described formula material through broken, dry, sieve after, to add in high speed mixer mix and blend 20 minutes, can product be obtained.
Compared with prior art, beneficial effect of the present invention is: adopt bagasse as fiber filling agent, avoid the introducing of plastic components, have economic environmental protection, advantage that cost is low; Meanwhile, improve product physical and chemical performance with wooden plastic fiber for auxiliary agent, there is stable performance, the advantage that smell is little.
