Abstract

The invention discloses fair-faced concrete and a preparation method thereof. The concrete is prepared from the following components in parts by weight: 30-40 parts of cement, 15-25 parts of volcanicash, 3-6 parts of nano hybrid hyperbranched polymer HB-SiO2, 75-85 parts of silica sand, 85-95 parts of coarse aggregate, 3-5 parts of basalt fibers, 1-3 parts of graphene oxide fibers, 7.5-8.5 partsof a composite additive, 15-20 parts of water, 1-3 parts of a carboxyl metal organic framework, 1-3 parts of zirconium citrate and 2-5 parts of zinc oxide nanofibers. The invention also provides a preparation method of the fair-faced concrete. The fair-faced concrete provided by the invention is better in comprehensive performance, higher in compressive strength and flowability, lower in bleedingrate, better in durability, environmental protection property and decorative effect, very good in appearance, smooth in surface and less in pores.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fair-faced concrete and a preparation method thereof. Background technique [0002] In recent years, with the progress of the society and the development of the economy, the enthusiasm for urban modernization has been high, and various construction projects have emerged one after another. Behind these projects, the use of building materials is inseparable. Building materials are the basis for ensuring the quality of engineering projects. Concrete is the most widely used man-made building material in contemporary times. It has the characteristics of rich raw materials, low price, simple production process, and good compressive performance. It is widely used in project construction. [0003] Fair-faced concrete is one-time pouring and molding without any external plastering and other decorations. At present, with the continuous improvement of people's environmental pro...
