一种用于改善混凝土耐久性能的组合物,包括单体10~50份、中和剂0~26份、还原剂0.01~0.50份、交联剂0.01~0.20份、改性剂1~10份、氧化剂0.05~0.30份、水20~90份重量份配比的原料。本发明专利技术采用在施工现场混合,对混凝土的微裂缝、微孔隙以及本体进行喷淋或浸渍,用远红外辐射原位合成高吸水性树脂。利用原位合成的吸水性树脂吸水膨胀、密实裂缝或孔隙,截断介质水的传输路径,提高了混凝土的耐久性能。经试验,采用本发明专利技术组合物处理的混凝土试件,其抗渗压力提高70%~180%,混凝土的抗冻性提高15%~35%,硫酸盐腐蚀后强度损失率降低57%~84%、质量损失降低56%~86%,抗氯离子渗透性提高1.7~8.50倍,抗碳化性能提高50%。

Composition for improving durability of concrete

A composition for improving the durability of concrete, including single 10 ~ 50, 0 ~ 26 neutralizing agent and reducing agent 0.01 - 0.50, 0.01 - 0.20, crosslinking agent modification agent 1 ~ 10, 0.05 ~ 0.30 oxidant and water 20 to 90 weight parts of raw materials. The invention adopts mixing in the construction field to spray or impregnate the micro crack, micro gap and the body of the concrete, and synthesize the superabsorbent resin in situ by far infrared radiation. The water absorption, swelling, dense cracks or pores of the in-situ synthesized water absorbent resin are used to cut off the transmission path of the medium water, so as to improve the durability of the concrete. After testing, the composition of the invention of concrete specimen, the impermeability pressure increases from 70% to 180%, the frost resistance of concrete is increased by 15% ~ 35%, the strength loss rate decreased by 57% ~ 84%, 56% ~ 86% mass loss decreased after corrosion of sulphate and chloride ion penetration resistance increased 1.7 ~ 8.50 times, the anti carbonation performance is improved 50%.
