High-durability micro-expansion green prestressed duct grouting material and preparation method thereof
The invention discloses a high-durability micro-expansion green prestressed duct grouting material and a preparation method thereof, and relates to the field of prestressed duct grouting materials, wherein the high-durability micro-expansion green prestressed duct grouting material comprises the following components in parts by weight: 40-50 parts of cement, 20-30 parts of ceramic waste residue, 18-23 parts of steel slag, 5-8 parts of microbeads, 2-5 parts of a water reducer, 0.1-1 part of an antifoaming agent, 0-5 parts of an expanding agent, and 0-0.05 part of a water-retaining agent, wherein the sum of the weight parts of the components is 100 parts, and the ceramic waste residue is a mixture of ceramic tile fragments and ceramic polishing residues. By implementing the method, the chloride ion erosion resistance and durability of the prestressed duct grouting material can be effectively improved, and meanwhile, the production cost is effectively reduced.
本发明公开了一种高耐久微膨胀绿色预应力孔道压浆料及其制备方法，涉及预应力孔道压浆料领域，其中，高耐久微膨胀绿色预应力孔道压浆料包括以下重量份的组分：水泥40~50份，陶瓷废渣20~30份，钢渣18~23份，微珠5~8份，减水剂2~5份，消泡剂0.1~1份，膨胀剂0~5份，保水剂0~0.05份；上述各组分的重量份之和为100份；其中，所述陶瓷废渣为陶瓷砖碎块与陶瓷抛光渣的混合物。实施本发明，可有效提升预应力孔道压浆料的抗氯离子侵蚀性能和耐久性能，同时有效降低生产成本。
