Embodiment 1

[0032] The selected hydration expansion material is burnt lime formed by calcining calcium oxide at 1000°C; the hydraulic material is Portland cement and gypsum; the hydration retarder is potassium carbonate, tartaric acid, citric acid; the water reducer is MNC -A 1 Early-strength superplasticizer; sodium bentonite as expansion booster; fly ash as cementation enhancer. Its weight ratio is as follows:

[0033] 80 parts of burnt lime; 6 parts of Portland cement; 3 parts of gypsum; 2.1 parts of potassium carbonate; 0.45 parts of tartaric acid; 0.45 parts of citric acid;

[0034] The above components are mixed and stirred evenly, ball milled with a ball mill, sieved with a 40-mesh sieve, and packaged in a plastic bag.

[0035] Use the static breaker of the present invention to process the material:

[0036] The size of the marble is 100cm×100cm×200cm. The diameter of the drilling hole is 4cm. According to the theory of drilling parameter design, the total length of the drillin...

Abstract

The invention relates to a static cracking agent prepared from the following components in parts by weight: 60-90 parts of hydrated expansive substance, 4-10 parts of hydraulic substance, 2-4 parts of hydration retardant, 1-2 parts of water reducer, 2-4 parts of expansion energizing agent and 1-31 parts of cementation reinforcer. In the static cracking agent of the invention, all the components are uniformly mixed, stirred, milled and screened to be encapsulated into a finished product. The static cracking agent of the invention is yellow powder, is non-inflammable and non-detonating, has high blasting efficiency, high yield, less scraps and hardly damaged stone structure and can be widely applied to cutting and mining marble, granite and various noble brittle materials.

Description

technical field [0001] The invention relates to a static breaking agent. Background technique [0002] With the rapid development of the modern construction industry, people's demand for stone is increasing, but the method of blasting is still commonly used to mine stone. Due to the destructiveness of blasting is not easy to control, the yield of stone mining is low, and it is generally accompanied by vibration, flying rocks, noise, a large amount of smoke and dust, and gas, which causes great damage and threat to the surrounding environment and safety. [0003] Static blasting is a blasting method that uses a static breaking agent to slowly load the crushed object until it cracks and breaks. Other parts of the substance will not be adversely affected. When the static breaking agent is applied to the crushing and cutting of stone, there is no need to consider the dosage, detonation device, explosion-proof measures, construction time and complicated design calculations.
