Description
本发明涉及一种灌浆材料，特别涉及一种湿式外包钢加固混凝土专用复合灌浆材料。The invention relates to a grouting material, in particular to a special composite grouting material for wet outsourcing steel-reinforced concrete.
目前我国湿式外包钢加固建筑结构规范采用两种施工技术，一种为乳胶砂浆粘贴，另一种为环氧树脂化学灌浆。前一种材料强度较低，施工时粘贴面不易平整，在大截面构件上更难保证外包钢钢架与原构件之间紧密相切，外包钢与混凝土共同工作性差，所以更常用的是后一种。但是环氧树脂化学灌浆材料在实际工程应用中存在一些缺点：价格高、耐久性差、易燃、有毒、易流尚，污染环境，配料麻烦，必须现用现配，计量必须准确，否则凝固快，甚至凝固在灌浆设备里，清洗困难，必须用有机溶剂方可清洗。At present, my country's wet outsourcing steel reinforced building structure code adopts two construction technologies, one is latex mortar paste, and the other is epoxy resin chemical grouting. The strength of the former material is low, and the paste surface is not easy to be smooth during construction. It is more difficult to ensure the close tangency between the outsourcing steel frame and the original component on large cross-section components. The outsourcing steel and concrete have poor workability, so the more commonly used It is the latter. However, epoxy resin chemical grouting materials have some disadvantages in practical engineering applications: high price, poor durability, flammable, toxic, easy to flow, pollute the environment, and troublesome ingredients. , or even solidified in the grouting equipment, it is difficult to clean and must be cleaned with organic solvents.
本发明的目的在于提供一种经济实用的灌浆材料，以代替环氧树脂化学灌浆材料，并具有良好的综合性能，易于施工，价格较低廉。The object of the present invention is to provide an economical and practical grouting material to replace epoxy resin chemical grouting material, which has good comprehensive performance, is easy to construct, and is relatively cheap.
本发明的目的是这样实现的：The purpose of the present invention is achieved like this:
湿式外包钢加固混凝土结构专用复合灌浆材料，其组分和含量是：The special composite grouting material for wet outsourcing steel reinforced concrete structure, its composition and content are:
普通硅酸盐水泥 80～100份；Ordinary Portland cement 80-100 parts;
铝酸盐水泥 0～20份；Aluminate cement 0～20 parts;
水溶性高聚物 1～10份；Water-soluble polymer 1-10 parts;
硬脂酸盐 0.3～3份；0.3-3 parts of stearate;
亚硝酸钠 0～5份；Sodium nitrite 0-5 parts;
分散剂 1～3份；Dispersant 1 to 3 parts;
二水石膏 0～20份。Dihydrate gypsum 0-20 parts.
该材料配方中普通硅酸盐水泥指425#～525#水泥，水溶性高聚物是指聚乙烯醇、纤维素或聚丙烯酸钠；分散剂是指萘磺酸盐甲醛缩合物或密胺树酯；硬脂酸盐是指硬脂酸铝、硬脂酸钙、硬脂酸锌。Ordinary Portland cement in this material formula refers to 425#～525# cement, water-soluble polymer refers to polyvinyl alcohol, cellulose or sodium polyacrylate; dispersant refers to naphthalene sulfonate formaldehyde condensate or melamine tree Esters; stearate refers to aluminum stearate, calcium stearate, zinc stearate.
以上是复合灌浆的干混合料。在施工中，将该干混合料加拌合水就可配成灌浆料。拌合水与灌浆干混合料重量比为0.2～0.5。Above is dry mix for composite grout. During construction, the dry mixture can be made into grouting material by adding mixing water. The weight ratio of mixing water to grouting dry mixture is 0.2-0.5.
本发明的优点是：The advantages of the present invention are:
1．价格低廉。按体积比计算，该发明的价格仅为环氧树脂化学灌浆料的30％左右。1. Inexpensive. Calculated by volume ratio, the price of the invention is only about 30% of the epoxy resin chemical grouting material.
2．流动性好，适用于0.2mm以上的灌缝。施工容易，既可灌又可粘贴和锚固，解决了环氧树脂只能灌，乳胶只能粘贴的施工难题。2. Good fluidity, suitable for filling joints above 0.2mm. The construction is easy, and it can be poured and pasted and anchored, which solves the construction problem that epoxy resin can only be poured and latex can only be pasted.
3．耐高温，在300℃下恒温8小时强度不下降。耐老化，灌成的钢架上面可以电焊，而环氧树脂化学灌浆料只能在80度以下工作，灌成的钢架上不能再电焊。3. High temperature resistance, the strength will not decrease at a constant temperature of 300°C for 8 hours. Anti-aging, the filled steel frame can be electric welded, and the epoxy resin chemical grouting material can only work below 80 degrees, and the filled steel frame can no longer be welded.
4．强度高，凝结时间可调、早期强度极高，2～3小时抗压强度可达20～30MPa、灌浆料28天抗压强度可达50～80MPa以上、无收缩、外包钢与混凝土共同工作性能好。4. High strength, adjustable setting time, extremely high early strength, compressive strength of 20-30MPa in 2-3 hours, compressive strength of 50-80MPa or more in 28 days of grouting material, no shrinkage, outsourcing steel and concrete work together Good performance.
5．现场配制容易，仅需在灌浆干混台料中加入拌合水。无污染，清理容易，施工后用水清洗方可。5. On-site preparation is easy, only need to add mixing water to the grouting dry mix. No pollution, easy to clean, just wash with water after construction.
本发明是申请人在进行大量材料性能试验研究和结构试验研究的基础上完成的。目前，该发明已在实地构件上进行了施工灌浆试验，实验证明，其施工性能良好，质量可靠。The present invention is completed on the basis of a large number of material performance test researches and structural test researches carried out by the applicant.
