Problems solved by technology

[0005] The above-mentioned stone powder and crushed stone refer to the use of single-quality stone, and they cannot be used if they are a mixture of more than two kinds. However, in Taiwan's stone processing industry, except for some factories that can process single-quality stone to obtain single-quality waste, most of them produce More than two kinds of mixed wastes are more difficult to deal with
In particular, the combination of fine particles of stone powder sludge and cement is very poor

example 1

[0026] Get the proportioning of solidifying agent (8020): stone powder: stream sand: side material crushed stone=22:11:28:39 weight ratio, carry out the making of every 5 tons of artificial fish reef body, to prove the practicability of the present invention. The following table is the comparison of the compressive strength of the uranium core test body of the artificial fish reef entity made with this formula after maintenance for 7 days and 28 days and the standard test body with a diameter of 10 cm and a height of 20 cm perfused with the same formula at the same time.

[0027] Specimen type

[0028] The above results show that the compressive strength of the artificial reef solid uranium core test body and the standard test body are consistent, which is consistent with the data obtained from the aforementioned experimental results.

example 2

[0030] Take 250 grams of curing agent composed of 80% of Bungalow Brand Type I cement and 20% of furnace stone powder, add 150 grams of dry stone powder, 250 grams of stream sand, 350 grams of scrap gravel and 40% of water, mix well and cast into diameter After 24 hours, the mold was dismantled and taken out from an iron mold of 8 cm and 16 cm in height, and the molded body was placed under natural conditions for 28 days, and its compressive strength was tested to be 200 kg per square centimeter, except that it can be used for wave breaking blocks and dikes, etc. In addition to uses, it is also suitable for parks, gardens, and paving.

Abstract

The present invention is stone waste solidifying treatment method. The mixture of type-I portland cement and blast furnace cinder in different ratio is used as the stone waste solidifying agent, while type-II portland cement being used for comparison. The solidified stone waste may be used as the useful resource.

Description

[0001] Field: [0002] The invention relates to the field of stone waste reuse, in particular to a stone waste solidification treatment method. Background technique: [0003] During the cutting and processing of natural stone such as granite, marble, serpentine, etc. (hereinafter referred to as stone), a large amount of water-containing stone powder sludge and side materials will be generated, especially the waste formed by stone powder. Except for part of the mud that can be used in artificial stone (resin is used as a binder), most of it has no proper use. At present, most of it is disposed of by burying or discarding. When the stone powder sludge is dry, it is easy to fly with the wind, causing environmental pollution. [0004] Natural Stone stone powder sludge Edge gravel granite marble serpentine man made rock Artificial stone, cement raw materials Artificial stone, refined magnesia, fertilizer paving, artificial stone Pavi...
