Description
技术领域technical field
本发明涉及一种适用于海工工程的抗冲蚀磷铝酸盐水泥基胶凝材料，属于建筑材料技术领域。The invention relates to an erosion-resistant aluminophosphate cement-based gelling material suitable for marine engineering, and belongs to the technical field of building materials.
背景技术Background technique
海洋环境是一种复杂的腐蚀环境，海水又是自然界中具有强腐蚀性的天然电解质，它含有大量腐蚀性离子，同时风、雨、波浪和海流的机械冲击等附加载荷的作用下，海水挟带悬移质泥沙或推移质泥沙运动，具有一定动能的硬质沙粒及其他悬浮物对泄水建筑物的过流壁面反复冲击与切削，造成过流壁面的磨损与断裂，主要表现为材料表面呈鱼鳞状凹坑和大量裂纹扩展，海事工程结构在这种侵蚀环境作用下其耐久性能不断劣化，从而引起承载能力下降导致结构破坏。因此海工用水泥除应具有强抗腐蚀能力外，也对混凝土抗冲磨能力提出了更高的要求，结构材料的特性是影响结构冲击磨损的关键因素。The marine environment is a complex corrosive environment. Seawater is a highly corrosive natural electrolyte in nature. It contains a large number of corrosive ions. With the movement of suspended sediment or moving sediment, hard sand particles and other suspended matter with certain kinetic energy repeatedly impact and cut the flow wall of the drainage structure, resulting in wear and fracture of the flow wall. The main manifestations are: Because the surface of the material has scale-like pits and a large number of cracks, the durability of marine engineering structures continues to deteriorate under the action of this erosive environment, resulting in a decrease in bearing capacity and structural damage. Therefore, in addition to strong corrosion resistance, marine cement should also have higher requirements for concrete abrasion resistance. The characteristics of structural materials are the key factors affecting structural impact wear.
目前海洋工程使用的结构材料主要为水泥混凝土结构，就使用效果而言，水泥混凝土材料是一种较好的结构材料。抗冲磨材料按胶凝材料分主要包括有机胶凝类和无机胶凝类，有机胶凝类主要有聚合物胶结混凝土、呋喃混凝土、环氧树脂混凝土等；无机胶凝类主要有硅粉混凝土、改性硅粉混凝土、纤维混凝土、粉煤灰混凝土等。针对混凝土的抗冲磨性能和抗裂性能，现有研究结果表明，掺硅粉混凝土的抗冲磨强度较高，但硅粉混凝土易出现塑性开裂；掺常规纤维混凝土的抗冲磨强度和韧性有所提高，但其碱度较高，不利于纤维的长期耐久性能；引入粉煤灰可提高混凝土抗裂性能，但其界面粘结力弱；聚合物可改善水泥柔韧性和抗裂性，但其分散性未得到有效解决，无法充分发挥其优势。同时，现有抗冲磨混凝土的抗离子侵蚀能力也较差，在海洋环境下的服役时间较短，远远达不到对海工工程服役时间要求。At present, the structural materials used in marine engineering are mainly cement concrete structures. In terms of use effects, cement concrete materials are a better structural material. Anti-scouring materials mainly include organic gelling materials and inorganic gelling materials according to cementitious materials. Organic gelling materials mainly include polymer cemented concrete, furan concrete, epoxy resin concrete, etc.; inorganic gelling materials mainly include silica fume concrete , Modified silica fume concrete, fiber concrete, fly ash concrete, etc. Aiming at the anti-abrasion performance and anti-cracking performance of concrete, the existing research results show that the anti-abrasion strength of concrete mixed with silica fume is higher, but the concrete with silica fume is prone to plastic cracking; the anti-abrasion strength and toughness of concrete mixed with conventional fiber It has been improved, but its alkalinity is high, which is not conducive to the long-term durability of the fiber; the introduction of fly ash can improve the crack resistance of concrete, but its interface adhesion is weak; the polymer can improve the flexibility and crack resistance of cement, However, its dispersion has not been effectively resolved, and its advantages cannot be fully utilized. At the same time, the existing anti-scouring concrete has poor ion erosion resistance, and its service time in the marine environment is short, which is far from meeting the service time requirements for marine engineering.
发明内容Contents of the invention
针对现有技术中存在的问题，本发明提供了一种用于海工工程的抗冲蚀磷铝酸盐水泥基胶凝材料。该凝胶材料利用高铁磷铝酸盐水泥早强高强、耐腐蚀、抗渗抗冻等性能，再掺和粉煤灰、碳化硅、橡胶粉、铝锆偶联剂、抗碱玻璃纤维等材料，使其具有良好的抗冲刷、磨蚀能力，充分发挥高聚物的性能，提高结构的抗氯离子渗透能力和抗冲磨能力。Aiming at the problems existing in the prior art, the invention provides an anti-erosion aluminophosphate cement-based cementitious material used in marine engineering. The gel material utilizes the properties of high-iron aluminophosphate cement, such as early strength, high strength, corrosion resistance, impermeability and frost resistance, and then blends fly ash, silicon carbide, rubber powder, aluminum-zirconium coupling agent, alkali-resistant glass fiber and other materials , so that it has good resistance to erosion and abrasion, fully exerts the performance of polymers, and improves the structure's resistance to chloride ion penetration and abrasion resistance.
本发明采用以下技术方案：The present invention adopts following technical scheme:
一种适用于海工工程的抗冲蚀磷铝酸盐水泥基凝胶材料，它是由以下重量百分比的原料制成：富铁磷铝酸盐水泥熟料60-75％，粉煤灰5-15％，碳化硅粉3-8％，橡胶粉2-6％，抗碱玻璃纤维3-6％，铝锆偶联剂0.5-2％。An erosion-resistant aluminophosphate cement-based gel material suitable for marine engineering, which is made of the following raw materials in weight percentage: iron-rich aluminophosphate cement clinker 60-75%, fly ash 5- 15%, silicon carbide powder 3-8%, rubber powder 2-6%, alkali-resistant glass fiber 3-6%, aluminum-zirconium coupling agent 0.5-2%.
优选的，所述富铁磷铝酸盐水泥熟料容积密度为2.98g/cm3，比表面积为319m2/kg，水泥细度为200目，筛余3.1％，凝结时间为初凝220min、终凝260min，铁相含量11％。Preferably, the iron-rich aluminophosphate cement clinker has a bulk density of 2.98g/cm 3 , a specific surface area of 319m 2 /kg, a cement fineness of 200 mesh, a sieve residue of 3.1%, and a setting time of 220 minutes for initial setting. The final setting time is 260min, and the content of iron phase is 11%.
优选的，所述富铁磷铝酸盐水泥熟料的矿相组成百分比含量为磷铝酸钙20-60％、磷酸钙10-30％、铝酸钙15-25％、铁铝酸四钙10-25％、玻璃体中间相2-10％。Preferably, the mineral phase composition percentage content of the iron-rich aluminophosphate cement clinker is 20-60% of calcium aluminophosphate, 10-30% of calcium phosphate, 15-25% of calcium aluminate, tetracalcium aluminoferrite 10-25%, vitreous mesophase 2-10%.
优选的，所述粉煤灰45μm筛筛余量为11.7％。Preferably, the 45 μm sieve residue of the fly ash is 11.7%.
优选的，所述碳化硅粉SiC含量＞96.5％。Preferably, the SiC content of the silicon carbide powder is >96.5%.
优选的，所述抗碱玻璃纤维抗拉强度＞350MPa。Preferably, the tensile strength of the alkali-resistant glass fiber is greater than 350 MPa.
混凝土掺硅粉可以提高抗冲磨强度，硅粉的掺入在这里体现的是它的物理填充作用。本文掺入的是碳化硅粉，化学式为SiC，经过实验证明SiC的加入可以提高水泥硬化浆体的抗冲磨性能。经橡胶粉改性后的水泥砂浆是由刚性和延性的材料复合而成的，高聚物按一定比例掺加时，在聚合物改性水泥砂浆中水泥水化生成物和聚合物将会形成相当于“微纤维”相互交叉的空间网络结构，从而增强水泥石基体，提高了基体抗磨损剥落的能力；铝锆偶联剂的加入，抑制了水泥体系“相”分离，又使矿物掺合料有机化且可较好的均匀分散，改善了结构的综合性能；高铁磷铝酸盐水泥是一种低碱度水泥，可长期发挥抗碱玻璃纤维的增强效应而不须担心玻璃纤维在水泥中的腐蚀损伤作用使玻璃纤维破坏，且方向杂乱的均匀分布使结构更为致密，提高结构的抗冲磨及抗侵蚀性能。此外，粉煤灰粒径较小，属于小型球状颗粒，可于水泥与碳化硅粉之间起到填隙作用，抗碱玻璃纤维与橡胶粉则属于大粒径角度对基体进行增强，各组分分工协作，共同达到抗侵蚀，耐磨性高，强度大的效果。Concrete mixed with silica fume can improve the abrasion resistance, and the addition of silica fume here reflects its physical filling effect. In this paper, silicon carbide powder is added, the chemical formula is SiC. Experiments have proved that the addition of SiC can improve the abrasion resistance of cement hardened paste. The cement mortar modified by rubber powder is composed of rigid and ductile materials. When high polymer is added in a certain proportion, cement hydration products and polymers will form in the polymer modified cement mortar. It is equivalent to the intersecting spatial network structure of "microfibers", thereby strengthening the cement stone matrix and improving the ability of the matrix to resist wear and peeling; the addition of aluminum-zirconium coupling agent inhibits the "phase" separation of the cement system, and makes the mineral blending The material is organic and can be uniformly dispersed, which improves the comprehensive performance of the structure; high-iron aluminophosphate cement is a kind of low-alkalinity cement, which can exert the reinforcing effect of alkali-resistant glass fiber for a long time without worrying about the glass fiber in the cement. The corrosion damage in the glass damages the glass fiber, and the uniform distribution of the direction makes the structure more dense, and improves the anti-erosion and anti-erosion performance of the structure. In addition, fly ash has a small particle size and is a small spherical particle, which can fill the gap between cement and silicon carbide powder. Alkali-resistant glass fiber and rubber powder belong to large particle sizes to strengthen the matrix. Division of labor and cooperation to jointly achieve the effects of corrosion resistance, high wear resistance and high strength.
本发明的有益效果如下：本发明在磷铝酸盐水泥的基础上提高其铁相(铁铝酸四钙)的含量，可以提高结构的抗冲磨性能；再掺和粉煤灰、碳化硅、橡胶粉、铝锆偶联剂、抗碱玻璃纤维等材料，粉煤灰、碳化硅粉和抗碱玻璃纤维含有游离Si2+，富铁磷铝酸盐水泥中的磷铝酸钙和铝酸钙水化产物可以跟Si2+反应生成水化钙铝黄长石，避免后期水化产物C3AH6的大量生成而产生的强度下降。此外，利用玻璃纤维的“桥接”作用，可以限制碳化硅粉加入后的塑形开裂，提高界面摩擦力和界面粘接力，普通硅酸盐水泥的PH在13左右，富铁磷铝酸盐水泥的PH在11左右，这种低碱环境更能发挥抗碱玻璃纤维的“桥接”作用，因而各组分共同协同作用使所获得的凝胶材料具有良好的抗冲刷、磨蚀能力，充分发挥高聚物的性能，提高结构的抗氯离子渗透能力和抗冲磨能力。The beneficial effects of the present invention are as follows: the present invention increases the content of its iron phase (tetracalcium aluminoferrite) on the basis of aluminophosphate cement, which can improve the anti-abrasion performance of the structure; then blending fly ash, silicon carbide , rubber powder, aluminum-zirconium coupling agent, alkali-resistant glass fiber and other materials, fly ash, silicon carbide powder and alkali-resistant glass fiber contain free Si 2+ , calcium aluminophosphate and aluminum in iron-rich aluminophosphate cement Calcium acid hydration products can react with Si 2+ to form hydrated calcium aluminum feldspar, avoiding the strength reduction caused by the large amount of hydration products C 3 AH 6 in the later stage. In addition, using the "bridging" effect of glass fiber can limit the plastic cracking after adding silicon carbide powder, and improve the interface friction and interface adhesion. The pH of ordinary Portland cement is about 13, and iron-rich aluminophosphate The pH of the cement is around 11. This low-alkali environment can better play the "bridging" effect of the alkali-resistant glass fiber. Therefore, the synergistic effect of each component makes the obtained gel material have good erosion resistance and abrasion resistance, and give full play to The performance of high polymer can improve the anti-chloride ion penetration ability and anti-abrasion ability of the structure.
