Embodiment 1

[0036] Embodiment 1: see figure 1 , a lime fly ash stabilized regenerated crushed stone method provided by the present embodiment, which comprises the following steps:

[0037] (1) Preparing raw materials: composed of the following components in weight percent:

[0038] Lime powder 4~8.5%,

[0039] Fly ash 12~16.5%,

[0040] Mixed crushed stone 75.5-84%;

[0041] (2) Feeding according to the proportion: take the lime powder, fly ash and mixed crushed stone of corresponding proportion, then add the lime powder, fly ash and mixed crushed stone in the mixing equipment;

[0042] (3) stirring and mixing: start the mixing equipment to stir until the stirring and mixing are uniform, and the mixture is obtained;

[0043] (4) Sampling: take out part of the mixture, and detect its weight percentage of each component of the mixture;

[0044] (5) finished product: if the percentage by weight of each component of the mixture is qualified, then take out the whole mixture, and make lime...

Abstract

The invention discloses a method used for stable regeneration of broken stone from lime flyash. The method comprises following steps: 1) raw material preparation, wherein lime powder, flyashe, and broken stone are prepared; 2) charging according to a ratio; 3) stirring and mixing; 4) sampling; and 5) preparation of a finished product. The invention also discloses a product obtained by using the method. Preparation processes of the method are simple and are easy to realize; production efficiency is high; waste building rubbish, concrete, components, coal gangue, steel slag, waste stone, muck, shale, and flyash can be recycled effectively; environment is protected, cost is reduced greatly, and excellent economic benefits and social benefits are obtained; in addition, formula design is reasonable, the raw materials are easily available, and traditional regenerated broken stone processes are simplified effectively; compressive strength of the product is high, the product is capable of satisfying demands of buildings on material performance, is convenient for construction, is capable of shortening construction period greatly and increasing construction efficiency, and is beneficial for wide popularization and application.

Description

technical field [0001] The invention belongs to the field of crushed stones, and in particular relates to a method for stabilizing and regenerating crushed stones with lime fly ash and a product obtained by implementing the method. Background technique [0002] For a long time, sand and gravel aggregates have been considered as inexhaustible raw materials due to their wide availability and low price. With the development of social economy, the demand for sand and gravel aggregates continues to increase. At present, our country is in an unprecedented upsurge of capital construction. The construction of a large number of projects requires a huge amount of sand and gravel aggregates, so that quarrying is everywhere and damages the environment. Due to the huge amount of sand and gravel aggregate mining, resource depletion and environmental damage caused by long-term mining have become the focus of attention, and the contradiction between the sustainable development of the const...
