Problems solved by technology

[0005] In the above-mentioned related technologies, the inventor believes that non-fired concrete is often damaged by friction during long-term use, and when a small amount of sparks accidentally appear, the instantaneous temperature is relatively high, which will cause damage to the internal structure of the concrete, causing great damage. Reduced service life of non-pyrophoric concrete

Embodiment 1

[0048] A kind of non-fire concrete, including the following components by weight: 200kg of water, 140kg of Portland cement, 800kg of dolomite-made crushed stone, 520kg of dolomite-made sand, 2.7kg of conductive titanium dioxide, and 0.9kg of hydrogenated castor oil ; The refractory filler is composed of potassium silicate 3kg, the water reducer is polycarboxylate water reducer 5kg, the wear agent is made of 90 mesh vitrified microbeads 0.9kg, silicon dioxide 0.7kg, talc powder 0.8kg and liquid sub Phosphate ester 0.6kg composition;

[0049] The preparation method of non-fire concrete comprises the following steps:

[0050] Step 1: Mix 200kg of water, 2.7kg of conductive titanium dioxide, 0.9kg of hydrogenated castor oil, and 3kg of potassium silicate, and stir at a speed of 850r / min for 35 minutes to form a suspension;

[0051]Step 2: the preparation method of wear-resisting agent, comprises the following steps:

[0052] Step 1: Mix evenly 0.9 kg of vitrified microbeads, 0.7...

Embodiment 12

[0060] The difference with Example 1 is that the preparation method of non-fired concrete comprises the following steps:

[0061] Step 1: Mix 200kg of water, 2.7kg of conductive titanium dioxide, 0.9kg of hydrogenated castor oil and 3kg of potassium silicate, and stir at a speed of 900r / min for 30 minutes to form a suspension;

[0062] Step 2: the preparation method of wear-resisting agent, comprises the following steps:

[0063] Step 1: Mix evenly 0.9 kg of vitrified microbeads, 0.7 kg of silicon dioxide, 0.8 kg of talc powder and 0.6 kg of liquid phosphite to obtain a mixture;

[0064] Step 2: Heat 0.6kg of liquid phosphite to 60°C and keep it warm. At a speed of 610r / min, add the mixture while stirring, and stir for 50 minutes to obtain an anti-wear agent.

[0065] Step 3: Add 140 kg of Portland cement, 800 kg of dolomite machine-made gravel, 520 kg of dolomite machine-made sand, 5 kg of polycarboxylate superplasticizer and the durable Abrasives.

Abstract

The application discloses a non-pyrophoric concrete and a preparation method thereof, belonging to the field of non-pyrophoric concrete, comprising the following components by weight: 180-230 parts of water; 115-160 parts of Portland cement; 710-100 parts of non-pyrophoric coarse aggregate 850 parts; 440-610 parts of non-pyrophoric fine aggregate; 1.5-3.3 parts of conductive titanium dioxide; 0.7-1.2 parts of hydrogenated castor oil; 3-5.5 parts of refractory filler; 5-9.5 parts of performance regulator; 2-5 parts of water reducing agent and 3-4.5 parts of wear-resistant agent. The non-fire concrete of the present application has the advantages of good fire resistance, good fire resistance and wear resistance.

Description

technical field [0001] The present application relates to the technical field of non-fired concrete, more specifically, it relates to a kind of non-fired concrete and a preparation method thereof. Background technique [0002] With the development of modern economy, there are special fire protection and explosion-proof systems in some military manufacturing, liquefied petroleum gas stations, gas production plants, oil depots, oil station docks, textile factories, printing factories and other flammable and explosive projects, warehouses and other areas. Requirements, in order to ensure safe production, the requirements for ground materials are very strict, and must be non-flammable. The so-called non-flammability means that "when the materials used have mechanical effects such as friction, impact or impact with hard objects such as metals or stones, no sparks (or sparks) will occur, resulting in the danger of fire or explosion caused by flammable materials. There are two rea...
