Examples of the experiments
The cement mineralizer prepared in examples 1-9 and comparative examples 1-4 was used in the sintering process of cement clinker, and the fineness, stability, setting time, flexural strength and compressive strength of the obtained cement clinker were measured according to GB/T8074-2008 "determination method of specific surface area of cement-Bo's method", GB/T1346-2011 "inspection method of standard consistency of cement, water consumption, setting time and stability", and GB/T17671-1999 "inspection method of strength of cement mortar (ISO method)", and the results of the measurements are shown in tables 1-5. Table 1 shows the results of the fineness measurement, table 2 shows the results of the stability measurement, table 3 shows the results of the setting time measurement, table 4 shows the results of the flexural strength measurement, and table 5 shows the results of the compressive strength measurement.
In the detection, the specific surface area of the item with fineness for checking is more than or equal to 300m2The/kg is qualified; in the stability detection, a boiling method is used for checking, and no crack or bending is qualified after the test; the initial setting time of the item of the setting time is greater than or equal to 45min and qualified, and the final setting time is less than or equal to 390min and qualified; the flexural strength of the product is qualified when the flexural strength is greater than or equal to 3.5Mpa in 3 days, and the flexural strength is greater than or equal to 6.5Mpa in 28 days; the compressive strength of the item is qualified when the compressive strength is greater than or equal to 17MPa in 3 days, and is qualified when the compressive strength is greater than or equal to 42.5MPa in 28 days.
TABLE 1
Figure BDA0003113561540000121
Figure BDA0003113561540000131
Comparing table 1 with analysis, it can be seen that the specific surface area of the cement mineralizer prepared in example 5 is the largest, and since the larger the specific surface area is, the greater the strength is, it can be seen that the cement mineralizer prepared in example 5 has the best strength. Comparing with comparative examples 1 to 5, it can be seen that the cement mineralizers prepared in comparative examples 1 and 2 are not qualified, while the specific surface area of comparative example 5 is much smaller than that of example 5, and it can be seen that triethanolamine, diethanol monoisopropanolamine and triisopropanolamine have a great influence on the strength of the prepared cement mineralizer.
TABLE 2
Figure BDA0003113561540000132
Figure BDA0003113561540000141
Analysis and comparison of table 2 show that comparative examples 1, 2 and 5 are not qualified, and that neither comparative example 1 nor comparative example 2 has the addition of diethanol monoisopropanolamine, and comparative example 5 has the addition of diethanol monoisopropanolamine and sodium thiosulfate.
TABLE 3
Figure BDA0003113561540000142
Figure BDA0003113561540000151
The initial setting time is the time required from the mixing of cement and water until the cement paste begins to lose plasticity. The setting time is the time required from when the cement mixes with water until the cement paste loses plasticity completely and begins to develop strength. Since cement sets, i.e. the cement reacts chemically with water and air, it takes a certain amount of time, and the longer the cement sets, the higher the cement set percentage and the higher the hardness. Comparing table 3 with analysis, it can be seen that the initial setting time of comparative example 2 is too short compared to the rest of the sample time, and the final setting time is too short, it can be seen that the hardness of the cement mineralizer of comparative example 2 is poor, compared to that of the cement mineralizer of example 5, the initial setting time of the mineralization of the cement is long, which means that the time required for losing plasticity is longer; the final setting time is longest and the time required for generating the intensity is longer, so that the intensity can be estimated to be optimal.
TABLE 4
Figure BDA0003113561540000161
Analyzing and comparing table 4, it can be seen that the cement mineralizer prepared in example 5 has the most improved flexural strength to cement, and the strength is the highest in 3 days and 28 days, compared to the cement mineralizer prepared in comparative examples 1 and 2, which has the least improved flexural strength to cement, indicating that the lack of triethanolamine, diethanol monoisopropanolamine and triisopropanolamine has a great influence on the flexural strength of the prepared cement mineralizer.
TABLE 5
Figure BDA0003113561540000171
Figure BDA0003113561540000181
Analyzing and comparing table 5, it can be seen that the cement mineralizer prepared in example 5 has the most improved compressive strength to cement, and the strength is the highest in 3 days and 28 days, compared to the cement mineralizer prepared in comparative examples 1 and 2, which has the least improved flexural strength to cement, indicating that the lack of triethanolamine, diethanol monoisopropanolamine and triisopropanolamine has a great influence on the compressive strength of the prepared cement mineralizer.
In conclusion, after the cement mineralizer prepared by the invention is added into cement, the hydration reaction of the cement can be effectively improved, the distribution of cement particles is uniform, and the potential activity of raw materials is not fully exerted in the cement production process is excited, so that the early and later strength of the cement is improved, the mineralizer has good adaptability with the cement, the consumption of the raw materials of the cement can be reduced, other cheaper mixed materials can be added, and the better structural strength is not obtained; in the grinding process, the flowability of the cement can be increased, the grinding efficiency of the cement is improved, the grinding energy consumption of the cement is reduced, and the purposes of reducing cost and improving efficiency are achieved; in addition, the cement mortar can also play a role in resisting freezing and comprehensively playing a role in improving the performance of cement.
