Artificial sand composite concrete and preparation method thereof
The invention relates to artificial sand composite concrete and a preparation method thereof, and belongs to the technical field of concrete.The composite concrete is prepared from cement, artificial sand, gravel, water, a water reducing agent, modified polyvinyl alcohol fibers, silicon carbide whiskers and steel fibers; the composite concrete further comprises methyl cellulose. The modified polyvinyl alcohol fiber is self-made, and the compressive strength of the composite concrete can be enhanced to a certain extent when the modified polyvinyl alcohol fiber is used for preparing the composite concrete. In addition, silicon carbide whiskers and steel fibers are doped on the basis of the self-made modified polyvinyl alcohol fibers to enhance the effect of the concrete, so that the composite concrete has excellent toughness due to the synergistic effect of the silicon carbide whiskers, the steel fibers and the self-made modified polyvinyl alcohol fibers; and the methyl cellulose can increase the orderliness of the flowing state of the system to a certain extent, prevent the clustering phenomenon between the fibers and the whiskers, and effectively assist in strengthening the toughness of the system to a certain extent.
本发明涉及一种人工砂复合混凝土及其制备方法，属于混凝土技术领域，所述复合混凝土包括如下组分原料：水泥，人工砂，碎石，水，减水剂，改性聚乙烯醇纤维、碳化硅晶须和钢纤维；所述复合混凝土还包括甲基纤维素。本发明自制了改性聚乙烯醇纤维，将其用于复合混凝土的制备上能一定程度强化复合混凝土的抗压强度。此外，本发明在自制改性聚乙烯醇纤维的基础上还复掺了碳化硅晶须和钢纤维对混凝土进行增效，三者能协效使得复合混凝土具有极好的韧性；而甲基纤维素能一定程度上增加体系流动状态的有序性，防止纤维和晶须间的成团现象，一定程度上有效协助强化体系的韧性。
