Preparation method of high-strength vegetation concrete
The invention relates to a preparation method of high-strength vegetation concrete, and belongs to the technical field of building materials. A modified polypropylene fiber and a basalt fiber are added, and the high-strength vegetation concrete is prepared; the polypropylene fiber can disperse the shrinkage energy of the concrete, prevents expansion of original micro-cracks in the concrete, and delays occurrence of new cracks; therefore, the continuity in the concrete material is enhanced, the brittleness and the strength of the vegetation concrete are improved to a great extent, so that the performance of the concrete is remarkably improved by reasonably doping the polypropylene fiber; the brittleness of the vegetation concrete can be effectively reduced, the bearing capacity of the vegetation concrete is improved, and the crack resistance and the impact resistance of the vegetation concrete are improved by doping the chopped basalt fiber into the vegetation concrete.
本发明涉及一种高强度植生混凝土的制备方法，属于建筑材料技术领域。本发明通过添加改性聚丙烯纤维和玄武岩纤维，制备一种高强度植生混凝土，聚丙烯纤维能分散混凝土的收缩能量，阻止混凝土中原有微裂缝的扩展，并且延缓新裂缝的出现，这样混凝土材料内部的连续性得到了增强，很大程度上改善了植生混凝土的脆性和强度，因此聚丙烯纤维的合理掺入使得混凝土的性能得到显著改善，在植生混凝土中掺入短切玄武岩纤维，可有效地降低植生混凝土的脆性，提高其承载力，改善其抗裂性能和抗冲击能力。
