And (6) demolding.
The curing mechanism of the present invention is further illustrated below:
1 solidification mechanism of solidifying agent to solidify oil field sludge
The research utilizes testing means such as a D/max-rA type X-ray diffractometer, an S-2500 type scanning electron microscope and the like to research the curing mechanism of the oil field sludge building ground tile.
1.1X-ray diffraction analysis
As shown in figure 1, the main crystal phase-calcite in the sludge raw material is rarely seen in the cured floor tile, and besides the quartz in the river sand as the filler, more minerals such as ettringite, calcium silicate hydrate, calcium carbo-aluminate and calcium aluminate hydrate are seen.
1.2 Electron microscopy analysis
Scanning electron micrographs are shown in fig. 2 and fig. 3, fig. 2 is an electron micrograph of an oilfield sludge ground tile cured for 7 days, fig. 3 is an electron micrograph of an oilfield sludge ground tile cured for 28 days, and comparing fig. 2 and fig. 3, it can be found that the structure of fig. 2 is loose, and the solid particles are less in cementing and bonding minerals, and generally only are hydration products of cement, namely calcium silicate hydrate; fig. 3 shows a compact structure, and various needle-like, rod-like, and sheet-like cementing substances are filled among the solid particles, and most of the cementing substances are minerals such as ettringite, calcium carbonate aluminate, and hydrated calcium aluminate formed by the combined action of curing agents, cement, and some components in oil field sludge.
2 study of curing mechanism
From the above X-ray diffraction analysis and electron microscopic analysis, it is known that there are two main parts, C in cement, which play a role in solidification during the whole solidification process of oilfield sludge3S、C2S and other minerals are hydrated to form hydrated calcium silicate, and the action can be represented by a formula(5-1): (formula 5-1)
Secondly, calcium carbonate in the sludge of the oil field and C in the cement3A reacts to form acicular calcium carbonate aluminate (C)3A·3CaCO3·32H2O and C3A·CaCO3·12H2O) its action can be represented by formulas 5-2 and 5-3: (formula 5-2) (formula 5-3)
Finally, the curing agent, the cement and the aluminum ions, the sulfate ions, the calcium ions and the like in the oil field sludge act together to form the ettringite.
1) The effect of cement
The cement and the waste mud are mixed with water and then have hydration reaction in cement hydrate, and the Calcium Silicate Hydrate (CSH) with the cementing effect is the main component which has the greatest contribution to the strength. Studies of cement chemistry have shown that:
(1) hydrated Calcium Silicate (CSH) produced in the liquid phase has a substantially constant Ca/S ratio, and Ca/Si is about 1.2. The thermodynamic equilibrium equation generated by CSH can be written as:
(2) liquid phase original Ca/Si, OH-The ratio of Si influences the type of hydration product when the original Ca/Si, OH of the liquid phase-When the ratio/Si is smaller, the silicic acid gel without the binding effect occupies a larger proportion in the hydration product along with the original Ca/Si, OH of the solution-The increase in the ratio/Si increases the proportion of CSH in the hydration product. From the thermodynamic equilibrium equation, liquid phaseCa2+、OH-Reduction of Ca (OH) in the pore water of cement2Under unsaturated conditions, the slurry must absorb a large amount of Ca necessary for the formation of CSH in order to achieve saturation adsorption2+、OH-This results in a decrease in the amount of CSH produced. In the process of forming cement soil, the slurry is coupled with OH-,Ca2+The absorption and cement hydration of (2) release Ca (OH)2Are performed simultaneously. Early mud to OH-,Ca2+The large amount of absorption may result in the original Ca/Si, OH of the cement pore water-The ratio of Si is too low, so that the amount of silicic acid gel without binding capacity in the cement hydration product is increased, and OH is further consumed-、Ca2+The production amount of CSH is further reduced. Slurry pair OH-,Ca2+The higher the absorption amount of (A), OH in the cement pore water-,Ca2+The lower the concentration, the less CSH is produced by hydration of the cement in the cement soil. The curing agent contains minerals with high calcium content such as lime, gypsum, etc. so that Ca (OH)2Ca in supersaturated concentration to form CSH gel2+And OH-The concentration is sufficiently high so that the bonding effect of the curing agent is good. In addition, the active material slag is greatly mixed to replace part of cement, and Ca (OH)2After the reaction is carried out, more hydrates such as CSH gel are generated and the strength of the hydrates is continuously developed.
2) The action of the curing agent
The oil field sludge sample has weak interparticle connection, and a large amount of pore water causes the strength of the sample to be low, so that the strength of the sample is improved, an ideal curing agent has double functions of cementing particles and filling pores, and experimental research shows that cement is used as the curing agent, main hydrate of the cement is hydrated calcium silicate, CSH has strong cementing capacity, loose sample particles can be cemented into a whole, but the efficiency of filling the pores is low, CSH gel is generated between the sample particles and particles, the CSH gel is attached to the pore walls of the pores of the sample, the pore wall sample is cemented into a whole, but the effect of filling the pores is weak, and a large amount of pores still exist. Although CSH enhances the interparticle connection, the curing strength is improved to a certain extent; however, it cannot compensate for the strength loss caused by the voids in the specimen, and the curing strength is not ideal. The curing agent contains gypsum, and when the curing agent is hydrated, the gypsum reacts with aluminum-containing phase to generate a large amount of ettringite besides the same reaction as that of cement. The ettringite is a needle-like crystal under certain conditions, and the solid phase volume of the ettringite can be increased by about 120 percent in the crystal forming process. On one hand, the ettringite exists, and on the other hand, the ettringite fills partial pores due to the expansion of the solid phase volume of the ettringite, so that the amount of the pores of the test body is reduced; on the other hand, larger needle-like crystals are generated in the pores, are mutually crossed to form a space structure together with calcium silicate hydrate, and are supported and filled in the pores with higher efficiency to thin the pore size distribution of a solidified body, and researches on porous materials show that: the strength of a material is inversely related to its amount of porosity, with less porosity giving a higher strength. When the pore volume is the same, the smaller the average pore diameter is, the higher the strength is, the pore volume in the solidified soil is reduced, the average pore diameter in the solidified body is reduced, the pores between the particles are connected through the CSH gel, compared with the case of no curing agent is added, the strength of the sample is greatly increased due to the generation of the CSH gel, the curing agent not only generates a large amount of CSH gel, but also generates a plurality of fine needle-shaped stones, the ettringite is mutually crossed with calcium silicate hydrate, and the two stones interact with each other, so that the curing effect of the curing agent is better.
From the above analysis, it can be seen that what plays a role in solidification in the oilfield sludge building ground tiles is the result of the combined action of the curing agent, cement and the le' an oilfield sludge.
In conclusion, the floor tile has high strength and no pollution, and meets the ecological and environmental protection requirements; the problems of pollution and discharge of sludge in the oil field are solved; the production method has the advantages of simple process and convenient manufacture.
