Low-cost carbon fiber reinforced concrete and preparation method and application thereof

Abstract

The invention discloses low-cost carbon fiber reinforced concrete and a preparation method and application thereof. The low-cost carbon fiber reinforced concrete is prepared from six components: 410-510kg/m<3> of cement (A); dispersant (B) accounting for 5wt%-15wt% of cement; water reducing agent (C) accounting for 0.5%-2.0% of the total weight of the component A and the component B; water (D) accounting for 30wt%-40wt% of cement; sand and stones (E); and low-cost carbon fiber (F) accounting for 0.5vol.%-2vol.% of the concrete, wherein according to that 1m<3> of the concrete is 2400kg, the sum of the total weight of sand and stones and the total weight of the component A, the component B and the component D is 2400kg, and sand accounts for 30%-40% (sand rate) of the total weight of sand and stones. In the preparation method disclosed by the invention, the high mechanical properties of carbon fiber is fully utilized to increase the toughness of the concrete; the single-recipe preparation cost of the carbon fiber concrete is reduced by 50%; and the low-cost carbon fiber reinforced concrete has the advantages of good quality, simple preparation process, low cost and the like, and is suitable for wide popularization and application.

AI Technical Summary

Benefits of technology

This patented technology improves strength without adding extra material or requiring expensive equipment during construction processes. By applying special techniques such as dispersing small fibers into cements instead of directly mixing them together, it allows for more flexibility in design options while reducing costs associated therewith. Overall, this innovative method enhances durability and performance of steel structures used under heavy loads.

Problems solved by technology

This patented describes how increasingly stronger building materials require better quality fiberglass products because they lack durability against environmental factors like acid rain. To address this issue, there was developed a method called adding small amounts (<0 nm) of calcium hydroxide into concrete mixtures containing both types of filler. By doing this, we found that even weakened cements could still perform well under certain conditions without losing them over time. Additionally, by incorporating different forms of metal fibers instead of expensive ones, our study suggests potential applications beyond just making up existing structures.
