High-performance self-compacting concrete for large-span highway-railway dual-purpose bridge
The invention relates to the field of concrete, and particularly discloses high-performance self-compacting concrete for a large-span highway-railway dual-purpose bridge. A high-performance self-compacting concrete for a large-span highway-railway dual-purpose bridge comprises 40-50 parts of cement, 35-45 parts of fly ash, 8-10 parts of coarse aggregate, 10-15 parts of a fine mixed admixture, 8-10 parts of vinyl acetate resin, 4-8 parts of polyacrylic acid resin, 5-6 parts of modified fibers and the balance of water, and the modified fibers are fibers obtained through organic siloxane modification. The product provided by the invention can be used for building a large-width highway-railway dual-purpose bridge, and has the advantages of good fluidity and high crack resistance.
本申请涉及混凝土领域，具体公开了一种大跨度公铁两用桥的高性能自密实混凝土。一种大跨度公铁两用桥的高性能自密实混凝土，包括水泥40‑50份、粉煤灰35‑45份、粗骨料8‑10份、细混合掺料10‑15份、醋酸乙烯树脂8‑10份、聚丙烯酸类树脂4‑8份、改性纤维5‑6份，其余为水，所述改性纤维为经过有机硅氧烷改性得到的纤维。本申请的产品可用于大阔度公铁两用桥的修建，其具有流动性好、抗裂性高的优点。
