摘 要:研究了水泥基渗透结晶型材料(XYPEX掺合剂)与纳米材料复掺(纳米CaCO3)对混凝土性能的影响。结果表明:适量XYPEX掺合剂与纳米CaCO3复掺可以改善混凝土的性能;3.0%的XYPEX掺合剂与0.5%的纳米CaCO3复掺可以显著提高混凝土的抗压强度;2.0%的XYPEX掺合剂与0.5%的纳米CaCO3复掺可以显著提高混凝土的早期劈裂抗拉强度;1.0%的XYPEX掺合剂与1.0%的纳米CaCO3复掺时,混凝土的抗冻性能最佳。
Abstract: The effect of cement based permeable crystalline materials(XYPEX admixture) and nano-material composite(nano CaCO3) on the performance of concrete was studied. The results show that the combination of XYPEX admixture and nano CaCO3 can improve the performance of concrete. The combination of 3.0% XYPEX admixture and 0.5% nano CaCO3 can significantly improve the compressive strength of concrete. The combination of 2.0% XYPEX admixture and 0.5% nano CaCO3 can significantly improve the early splitting tensile strength of concrete. When 1.0% XYPEX admixture is combined with 1.0% nano CaCO3, the frost resistance of concrete is the best.
