Full-scale fiber toughened ultra-high performance concrete and preparation method thereof
The invention discloses a full-scale fiber toughened ultra-high performance concrete and a preparation method thereof. Fibers, which are used in the ultra-high performance concrete and are used for toughening the ultra-high performance concrete, are divided into millimeter-scale fibers, micron-scale fibers and nano-scale fibers in a full-scale range. Fibers with three scales are matched based on the stress characteristics of the ultra-high performance concrete so as to meet different requirements on mechanical properties. The concrete comprises the following components in parts by weight: 90 to 250 parts of full-scale fibers, 600 to 900 parts of cement, 100 to 300 parts of mineral powder, 100 to 200 parts of silica fume, 900 to 1200 parts of fine aggregate, 8 to 15 parts of additive and 160 to 190 parts of water. The ultra-high performance concrete is toughened by full-scale fibers in the millimeter, micrometer, and nanometer scales, and thus the cracks in different scales can be constrained and controlled, when a force is applied on the ultra-high performance concrete.
本发明公开一种全尺度纤维增韧超高性能混凝土及其制备方法，将超高性能混凝土中所用纤维分为全尺度范围内的毫米尺度、微米尺度以及纳米尺度三种尺度的纤维，进行超高性能混凝土的增韧；并通过超高性能混凝土的受力特点搭配三种不同尺度的纤维，从而满足不同需求的力学性能要求，包括以下重量份的组分：全尺度纤维90～250份、水泥600～900份、矿粉100～300份、硅灰100～200份、细骨料900～1200份、外加剂8～15份、水160～190份。本发明通过全尺度的纤维方式，从毫米、微米和纳米三个层面上进行超高性能混凝土的增韧，从而实现超高性能混凝土在受力情况下，对不同尺度的裂缝进行约束和控制的效果。
