Ultrahigh-property concrete and preparation method thereof

Abstract

The invention discloses ultrahigh-property concrete which comprises the following components by weight: 500-850kg/m<3> of cement, 50-150kg/m<3> of coal ash, 80-150kg/m<3> of silicon ash, 1000-1300kg/m<3> of sand, 80-160kg/m<3> of a steel fiber, 20-60kg/m<3> of a polymer emulsion, 60-180kg/m<3> of water, 30-40kg/m<3> of a water reduction agent and 0.1-1kg/m<3> of filming aids. By adopting the ultrahigh-property concrete, the waterproof anti-seepage property and the overall strength can be remarkably improved. The invention further provides a preparation method which is easy to implement and capable of preparing the ultrahigh-property concrete which is rapid and convenient to prepare, environmental-friendly and energy-saving and low in cost.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to an ultra-high performance concrete and a manufacturing method thereof. Background technique [0002] In the prior art, concrete has been applied to various fields, such as: integral sanitary ware, see Chinese patent announcement number: CN204645718U, discloses to use a kind of ultra-high performance concrete as the bottom plate, but they do not have waterproof treatment, just the ultra-high performance concrete Direct application has the problem of waterproof and anti-seepage of materials, especially in long-term use, the penetration of harmful impurities such as chloride ions makes steel fibers easier to rust; and the volume expansion of rusty products causes material damage, making the material waterproof and anti-seepage Sex is greatly reduced. Another example is the Chinese patent announcement number: CN104591635B, which discloses a kind of ultra-high performance concrete m...

[0002] In the prior art, concrete has been applied to various fields, such as: integral sanitary ware, see Chinese patent announcement number: CN204645718U, which discloses the use of a kind of ultra-high performance concrete as the bottom plate, but they do not have waterproof treatment, only the ultra-high performance concrete Direct application has the problem of waterproof and anti-seepage of materials, especially in long-term use, the penetration of harmful impurities such as chloride ions makes steel fibers easier to rust; and the volume expansion of rusty products causes material damage, making the material waterproof and anti-seepage greatly reduced sex

Another example is the Chinese patent announcement number: CN104591635B, which discloses a kind of ultra-high performance concrete modified with water-based epoxy resin. The super-strong bonding performance of the water-based epoxy resin used in it improves the connection performance between steel fiber and cement matrix; but The polymers are not interconnected to form a film, which does not significantly improve the waterproof performance
