Embodiment Construction

[0025] A method for preparing artificial stone, comprising the steps of:

[0026] 1. Crush the large limestone to 40-50 mm, send it to the resistance furnace with a bucket elevator, bake and modify half-baked and slightly oxidized with CO 2 After discharge, stop the furnace and cool down, manually push it into the wheel mill, then crush it to 5-10mm, and transport it to the silo for preparation by elevator.

[0027] 2. The sand is loaded and transported from the sand storehouse by the dump truck to the bucket elevator, and then transported to the silo for material preparation. The sand particle size is 0.2-1.0mm.

[0028] 3. Use the disc feeder at the lower part of the limestone and sand silos to adjust the ratio of sand and limestone to a weight ratio of 100:5-10, and then send it to the mixing mixer for mixing operation until it is uniform. Water is added to moisten and discharge the material when it is sticky, and it is lifted by the bucket elevator to the silo of the bri...

Abstract

The invention provides an artificial stone. The stone is mainly prepared by the following steps: adding a proper amount of water into drying or calcining modified limestone having a granularity of 5-10mm and sands having a granularity of 2-5mm in a weight ratio of 100:(5-10), uniformly mixing, and preparing an irregular artificial stone blank by a mold; pouring into a carbonizing tank, adding CO2 to enable the pressure to be 0.5kg / cm<2>, and maintaining the pressure to react for 20-24 hours. The artificial stone does not need soil, so that earth resource is saved; sintering is not used, so that energy can be saved, and environmental pollution can be reduced. Furthermore, limestone and sands are rich in resource and can be widely popularized and applied, so that popularization and application of the artificial stone have excellent economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an artificial stone and a preparation method thereof. Background technique [0002] With the rapid development of national economic construction, the demand for building materials is increasing. The traditional building materials currently used in the construction industry are still bricks, tiles or ceramic materials. many still [0003] Utilize the old method to artificially make bricks and tiles out of clay, dry them in the sun, and sinter them into kilns. Bricks and tile pottery are affected by the composition and structure of the soil. Clay bricks and tiles have the disadvantages of low strength, no corrosion resistance, weathering, etc., resulting in low structural strength and short life of the building. In particular, building material resources and agriculture compete for land. To build a large building requires digging a large hole, and a large ...
