Embodiment 1

[0034] Embodiment 1: see figure 1 , a cement-stabilized regenerated gravel method provided in this embodiment, is characterized in that it comprises the following steps:

[0035] (1) Preparing raw materials: composed of the following components in weight percent:

[0036] Cement 4-8%,

[0037] Regenerated coarse and fine aggregate 92-96%;

[0038] (2) Adding materials according to the proportion: weighing the cement and the regenerated coarse and fine aggregate of the corresponding proportion, and then adding the cement and the regenerated coarse and fine aggregate to the mixing equipment to prepare the mixture; the cement is Portland cement;

[0039] (3) Stirring and adding water: start the mixing equipment to stir the mixture, then add water to make the water content of the mixture 7.9-9.3%, until the mixing is uniform, and the cement-stabilized recycled gravel product is obtained.

[0040] The regenerated coarse and fine aggregate is one or more of waste concrete, compon...

Abstract

The invention discloses a method of stably regenerating gravel from cement. The method includes steps of: 1) preparing raw materials comprising the cement and regenerated crude and fine aggregate; 2) adding the raw materials according to a ratio; and 3) stirring, and adding water to obtain a finished product. The invention also discloses a product obtained by the method. The method is simple in preparation technology, easy to achieve, and high in production efficiency, and can rapidly and stably produce the gravel product with high compressive strength by utilization of the cement. The method has high production efficiency, largely reduced cost, and good economic and social benefit, and protects the environment. The design of the formula is reasonable. The raw materials are easily available. Processes of traditional gravel exploiting are effectively simplified. The compressive strength of the product is high and can meet requirements of buildings with respect to material performances, thus solving the gravel resource shortage problem and achieving objectives of environment protection and sustainable development. The product is easy to construct, shortens the time limit for a project, improves the construction efficiency and facilitates wide popularization and application.

Description

technical field [0001] The invention belongs to the field of regenerated gravel, and in particular relates to a cement-stabilized regenerated gravel method and products obtained by implementing the method. Background technique [0002] Grit refers to a mixture of sand and gravel, pebbles and boulders (a type of rock that has been eroded by water or weather) are also known as gravel. Gravel is the best material for building roads and building foundations. It is easy to compact, has high bearing capacity, and has strong resistance to capillary water damage. For a long time, sand and gravel have been considered as inexhaustible raw materials due to their wide availability and low price. [0003] With the development of social economy, the demand for gravel 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, so that it is mined everywhere...
