Prestressed pipeline grouting material and preparation method thereof
The invention relates to the technical field of grouting materials, and discloses a prestressed pipeline grouting material which comprises the following raw materials in parts by weight: cement, a water reducing agent, a defoaming agent, slag powder and silica fume neoprene latex. According to the prestressed pipeline grouting material and the preparation method thereof, the grouting material is prepared by stirring the cement, the water reducing agent, the defoaming agent, the slag powder and the silica fume neoprene latex, and the addition of a proper amount of the polycarboxylic acid water reducing agent can ensure that the grouting material does not bleed and keeps good fluidity; by adding the defoaming agent, bubbles generated in the slurry stirring process can be eliminated, the slurry is fuller and more compact, the compressive strength of the grouting material is improved, the compressive strength is high, the later strength can reach 100 MPa or above and is far better than that of similar products, meanwhile, the grouting material has good fluidity, the slurry is full, compact and seamless, the grouting material is firmly bonded with concrete, corrosion of prestressed steel bars is prevented, and the service life of the grouting material is prolonged. In addition, a proper amount of silica fume neoprene latex is added during stirring, and the silica fume neoprene latex is high polymer molecule modified high polymer waterproof and corrosion-resistant.
本发明涉及压浆料技术领域,且公开了一种预应力管道压浆料,包括以下重量份数配比的原料:水泥、减水剂、消泡剂、矿渣粉和硅灰氯丁胶乳。该预应力管道压浆料及其制备方法,通过水泥、减水剂、消泡剂、矿渣粉和硅灰氯丁胶乳进行搅拌制备,增加聚羧酸减水剂的适量添加可以保证浆体不泌水,且保持良好的流动性;消泡剂的添加可以消除浆体搅拌过程中产生的气泡,使浆体更饱满密实,提高压浆料的抗压强度,抗压强度高,后期强度可达到100MPa以上,远远超过同类产品,同时具有良好的流动性,浆体饱满密实无缝隙,与混凝土粘结牢固,防止预应力钢筋锈蚀,而且在搅拌时适量的加入硅灰氯丁胶乳,硅灰氯丁胶乳时高聚物分子改性基高分子防水防腐。
