Description
技术领域technical field

背景技术Background technique
钢筋混凝土结构在土木工程中的应用范围极广，各种工程结构都可采用钢筋混凝土建造，这主要是因为钢筋混凝土结构具有整体性好、可模性好、耐久性好、耐火性好等诸多有点，但是也存在自重大、抗拉强度较低易造成开裂、费工且费模板周期长、修补困难等缺点。因此，建筑时间长了会出现缺陷，例如混凝土开裂未及时修复或修补不得当，降低对钢筋的保护能力，导致破坏加速,寿命大大降低建筑的使用寿命；还有自然的侵蚀风化作用，造成建筑的缺角、表面破损等；或是混凝土路面出现的压痕、破坏、塌陷(小规模)；如果后期维护对这类缺陷进行良好的修复，这样建筑或混凝土路面的寿命会大大提高。Reinforced concrete structures have a wide range of applications in civil engineering, and various engineering structures can be constructed with reinforced concrete, mainly because reinforced concrete structures have good integrity, good moldability, good durability, and good fire resistance. A little bit, but there are also disadvantages such as heavy weight, low tensile strength, easy to cause cracking, labor-intensive and long template cycle, and difficult repairs. Therefore, defects will appear after a long time of construction, such as concrete cracks that are not repaired in time or repaired improperly, which reduces the protection ability of steel bars, leads to accelerated damage, and greatly reduces the service life of the building; there is also natural erosion and weathering, which causes the building The lack of corners, surface damage, etc.; or the indentation, damage, and collapse of the concrete pavement (small scale); if such defects are well repaired in the later maintenance, the life of the building or concrete pavement will be greatly improved.
根据上述问题，常常采用混凝土包括硅酸盐水泥、硫酸盐水泥等或是其他砂浆材料进行修复，但其修复周期长、修复料和钢筋混凝土/混凝土连接程度不佳、材料成本较高、二次老化、腐蚀等，此外例如对混凝土路面等裂缝处进行修复，需先设立V型凹槽、连接凹槽等之后在进行施工，施工过程繁琐。According to the above problems, concrete including Portland cement, sulfate cement, etc. or other mortar materials are often used for repair, but the repair period is long, the connection between the repair material and reinforced concrete/concrete is not good, the material cost is high, and the secondary Aging, corrosion, etc. In addition, for example, to repair cracks on concrete pavement, it is necessary to set up V-shaped grooves, connecting grooves, etc. before construction, and the construction process is cumbersome.

结合实施例3、4、5、6、7以及碳化压力，进一步说在允许范围内碳化时间和养护气体中二氧化碳的含量以及碳化压力越高其碳化程度越好，其结构越加致密、抗压强度越高；但是碳化达到一定程度(饱含、近似饱和、检测合格程度)后，碳化时间过长反而易造成养护气体浪费等，增加成本等；碳化压力、碳化时间同理。In combination with Examples 3, 4, 5, 6, 7 and the carbonization pressure, it is further stated that the carbonization time and the content of carbon dioxide in the curing gas and the carbonization pressure are within the allowable range. The higher the strength; but after the carbonization reaches a certain level (fullness, near saturation, and qualified degree of detection), too long carbonization time will easily cause waste of curing gas and increase costs; the same is true for carbonization pressure and carbonization time.
对比例1:Comparative example 1:
对比例1与实施例1～3不同之处在于采用现有技术常规的修复和养护方法(非本申请中涉及的碳化养护)。The difference between Comparative Example 1 and Examples 1-3 is that conventional repair and maintenance methods in the prior art (not the carbonization maintenance involved in this application) are adopted.
实施例1～3与对比例1，在相同的条件下分别对100mmX100mmX80mm的钢筋混凝土块就相近的破损凹槽就行修复，修复后分别对钢筋混凝土块的修补处进行抗压强度、抗冻性、紫外线老化试验、结合度、盐雾试验，其结果如下表4所示：Embodiments 1 to 3 and comparative example 1, under the same conditions, the reinforced concrete block of 100mm * 100mm * 80mm is repaired with respect to similar damaged grooves, and after the repair, the repaired parts of the reinforced concrete block are respectively subjected to compressive strength, frost resistance, The results of ultraviolet aging test, combination degree and salt spray test are shown in Table 4 below:
表4:实施例1～3与对比例1试验结果Table 4: embodiment 1～3 and comparative example 1 test result
根据试验结果可知，实施例1～3的抗压强度、抗冻性、对紫外线的耐受能力、修复料与修补处的结合程度以及盐雾测试结果均优于对比例1，这是由于修复料中的胶凝材料碳化后结构更佳致密稳定，从而有效说明本申请提供的修复料具有良好抗压强度、抗冻特性，对紫外线的耐受力强，且结合度、耐腐蚀性能好。According to the test results, it can be seen that the compressive strength, frost resistance, resistance to ultraviolet rays, the combination degree of the repair material and the repaired part, and the salt spray test results of Examples 1 to 3 are better than those of Comparative Example 1. This is because the repair The structure of the cementitious material in the material is more dense and stable after carbonization, which effectively shows that the repair material provided by this application has good compressive strength, anti-freezing properties, strong resistance to ultraviolet rays, and good bonding and corrosion resistance.
对比例2：Comparative example 2:
实施例1～3、对比例1和对比例2，在相同的条件下分别对100mmX100mmX80mm的钢筋混凝土块就相近的破损凹槽就行修复；Embodiments 1 to 3, comparative example 1 and comparative example 2, under the same conditions, the reinforced concrete block of 100mm * 100mm * 80mm is just repaired with respect to the similar damaged groove;

表5：实施例1～3、对比例1与对比例2抗压强度试验结果Table 5: Results of compressive strength tests of Examples 1 to 3, Comparative Example 1 and Comparative Example 2
根据试验结果可知，对比例2与实施例1～3相对比，对比例2的抗压强度均低于实施例1～3，这是由于对比例2未添加起到骨架支撑作用的岩棉颗粒与起到增韧作用的丝状岩棉，导致其抗压强度不佳；According to the test results, it can be seen that the compressive strength of Comparative Example 2 is lower than that of Examples 1-3 compared with Examples 1-3, this is because Comparative Example 2 does not add rock wool particles that play a role in skeleton support And the filamentous rock wool that plays a toughening role, resulting in poor compressive strength;
对比例2与对比例1相对比，对比例2的抗压强度高于对比例1的抗压强度，这是由于对比例2提供的钢筋混凝土结构的修复料中胶凝材料经过碳化后有效提高其抗压强度；进一步说明添加岩棉颗粒和丝状岩棉不止可以将废旧岩棉有效利用起来，更是可以起到增强效果，实现高价值的废物利用目标。Comparative example 2 is compared with comparative example 1, and the compressive strength of comparative example 2 is higher than that of comparative example 1. This is because the cementitious material in the repairing material for reinforced concrete structure provided by comparative example 2 is effectively improved after carbonization. Its compressive strength further shows that the addition of rock wool particles and filamentary rock wool can not only effectively utilize waste rock wool, but also enhance the effect and achieve high-value waste utilization goals.

实施例8与实施例1～3不同之处在于，实施例8中添加陶瓷渣1份、贝壳渣1份；The difference between Example 8 and Examples 1-3 is that in Example 8, 1 part of ceramic slag and 1 part of shell slag are added;
实施例9Example 9
实施例9与实施例1～3不同之处在于，实施例9中添加陶瓷渣2份、贝壳渣2份；The difference between Example 9 and Examples 1-3 is that 2 parts of ceramic slag and 2 parts of shell slag are added in Example 9;
实施例10Example 10
实施例10与实施例1～3不同之处在于，实施例10中添加陶瓷渣3份、贝壳渣3份；The difference between Example 10 and Examples 1-3 is that 3 parts of ceramic slag and 3 parts of shell slag are added in Example 10;
实施例1～3、实施例8-10，在相同的条件下分别对200mmX200mmX150mm的钢筋混凝土块就相近的破损凹槽就行修复；Embodiment 1～3, embodiment 8-10, under the same condition, the reinforced concrete block of 200mm * 200mm * 150mm is just repaired with respect to the similar damage groove respectively;
分别对实施例1～3、实施例8-10进行抗水渗透性能试验，抗渗仪施加水压力范围为0.1～2.0MPa，具体测试结果如表6所示：Examples 1-3 and Examples 8-10 were respectively tested for water penetration resistance. The water pressure applied by the anti-seepage instrument ranged from 0.1 to 2.0 MPa. The specific test results are shown in Table 6:
表7：实施例1～3、实施例8-10的抗水渗透性能试验结果Table 7: Test results of water penetration resistance of Examples 1 to 3 and Examples 8-10
根据试验结果可知，实施例8-10与实施例1～3相对比，实施例8-10的抗水渗透性能与实施例1～3相近或更优一些，这是由于实施例8-10中添加疏水性陶瓷渣、贝壳渣，二者与胶凝材料结合后提高防水性能。According to the test results, it can be seen that, compared with Examples 1 to 3, the water penetration resistance of Examples 8-10 is similar to or better than that of Examples 1 to 3. This is due to the fact that in Examples 8-10 Hydrophobic ceramic slag and shell slag are added to improve the waterproof performance after the two are combined with the cementitious material.
实施例8-10与对比例1相对比，实施例8-10的耐磨防水性能均高于对比例1，这是由于实施例8-10提供的钢筋混凝土结构的修复料中胶凝材料与陶瓷渣、贝壳渣起到了增效的作用；进一步说明添加陶瓷渣、贝壳渣是可行的，不仅仅将废弃的陶瓷渣、贝壳渣有效利用起来，更是可以起到防水效果，且随着陶瓷渣、贝壳渣添加量的增加，其防水性能逐渐提高。Embodiment 8-10 is compared with comparative example 1, and the wear-resisting waterproof performance of embodiment 8-10 is all higher than comparative example 1, and this is because the cementitious material in the restoration material of reinforced concrete structure that embodiment 8-10 provides and Ceramic slag and shell slag play a synergistic role; it further shows that it is feasible to add ceramic slag and shell slag, not only to effectively use the discarded ceramic slag and shell slag, but also to play a waterproof effect. The increase in the amount of slag and shell slag added gradually improves its waterproof performance.
