Correlation detection
The comparative data of the compressive strength of the carbonized stones obtained in examples 1 to 3 and comparative examples 1 to 4 were examined, and the results are shown in fig. 1 and table 1:
TABLE 1 preparation conditions and compressive strength data for the examples and comparative examples
Therefore, the compressive strength of the stone with the water loss rate of about 58 percent is higher than that of the carbonized stone with the water loss rate of 32 percent and the water loss rate of 75 percent no matter the carbonized steel slag is added. This is because the moisture content is too low, limiting CO 2 With Ca 2+ 、Mg 2+ The carbonization degree is reduced by dissolution from the inside of the particles; too high a moisture content will saturate a large number of pores, CO 2 Migration into the interior is hindered.
When the carbonized steel slag is added into the raw materials as the fine aggregate, the compressive strength is optimal compared with the stone without the carbonized steel slag and the fine aggregate of the quartz sand. This is because most of the sand grains of the carbonized steel slag have absorbed CO when it is used as fine aggregate 2 Plays the roles of supporting and pore passage for the cementing material in the secondary carbonization process and promotes CO 2 Enter the interior of the stone material, thereby promoting the reaction to be complete; and a small part of sand grains which are not completely carbonized continuously participate in the carbonization reaction in the secondary carbonization, so that the strength of the stone is improved. The compressive strength of the pouring type carbonized stone reaches and exceeds the strength standard of natural stone, and the pouring type carbonized stone has certain research significance.
Different carbonized stones prepared in examples 1 to 3 and comparative examples 1 to 4 were subjected to a carbonization performance test;
the test process is as follows: CO at a concentration of 50% 2 Placing the support with the plate in a cylindrical pressure tank with the caliber of 50cm and the height of 80cm for a gas environment, sealing and locking, ventilating and exhausting for 5 minutes, checking whether gas leaks or not, finally aerating to 0.1MPa, closing an exhaust hole, reacting for 24 hours, taking out, and calculating the ignition loss, wherein the calculation formula is as follows:
14/11*(M 3 -M 2 )/(M 3 -M 0 )a％
M 0 : quality after carbonization; m 2 : calcined at 500 ℃ and then the mass; m is a group of 3 : calcined at 1000 ℃ and then the mass; a%: caO content percentage.
Carbonization comparative data are shown in fig. 2 and table 2:
TABLE 2 preparation conditions and carbonization degree data of examples and comparative examples
The carbonized stone material of example 2 has the best carbonization degree, which shows that the water content influences the carbonization of the stone material, when the water loss rate is about 58%, the water content is favorable for carbonization reaction, the void structure can not be blocked, and simultaneously, the fully carbonized particles in the carbonized steel slag can be used as fine aggregate to play the roles of supporting and porosity in the cementing material, and CO is added 2 Enters a passage in the stone material to promote the carbonization reaction of the cementing material, and the sand grains which are not completely carbonized in the carbonized steel slag can continuously participate in the secondary carbonization.
