Grouting material and preparation process thereof
The invention relates to the field of prestressed concrete, in particular to a grouting material and a preparation process thereof.The grouting material is prepared from 40-55 parts of cement, 20-30 parts of industrial waste residues, 5-10 parts of fly ash, 1-5 parts of modified ardealite, 1-5 parts of an exciting agent, 1-3 parts of a corrosion inhibitor, 0.1-0.5 part of an expanding agent, 0.1-0.5 part of an air entraining agent, 0.1-0.3 part of a water reducing agent and 0.01-0.06 part of a defoaming agent. The cement and the industrial waste residues are adopted as main raw materials and are precisely proportioned with other additives, so that the prepared grouting material is good in quality stability, good in fluidity, small in slurry bleeding, not prone to segregation and layering, smooth in grouting, not prone to pipe blocking and not prone to corrosion of reinforcing steel bars, the hardened slurry is dense, pore channels are full, and the service life of the grouting material is prolonged. The bonding strength with prestressed steel bars is large, after solidification, the structural strength is high, cracks cannot be generated after a period of time, and the durability of constructional engineering, bridge engineering and the like is effectively improved.
本发明涉及预应力混凝土领域，其具体是一种压浆料及其制备工艺,本发明采用水泥40～55份，工业废渣20～30份，粉煤灰5～10份，改性磷石膏1～5份，激发剂1～5份，阻锈剂1～3份，膨胀剂0.1～0.5份，引气剂0.1～0.5份，减水剂0.1～0.3份，消泡剂0.01～0.06份制得，通过采用水泥以及工业废渣为主要原料与其它的外加剂的精确配比，制备的压浆料质量稳定性好，流动性好，浆体泌水小，不易离析分层，浆体压浆时顺畅，浆体压浆时不易堵管，不易对钢筋产生锈蚀，硬化后浆体密实，孔道饱满，与预应力钢筋粘结力度大，凝固后，结构强度高，一段时间后，也不会产生裂缝，有效提高了建筑工程，桥梁工程等的耐久性。
