Abstract

The invention discloses a concrete additive, which is characterized by being prepared from the following components in parts by weight: 2 to 5 parts of phosphate s-triazinyl hyperbranched macromolecular compound, 8 to 12 parts of sulfonic diethanol amine / 1, 3-adamantane diacetic acid condensation polymer, 1 to 3 parts of attapulgite and 1 to 4 parts of graphene oxide fiber. The invention also discloses a preparation method of the concrete additive. The concrete additive disclosed by the invention is more excellent in water reducing effect, less in mixing amount, better in environmental protection property and plasticizing effect, diverse in function, more remarkable in effect of improving the strength, flowability, durability and impermeability of a concrete material, free of negative influence on the comprehensive performance of concrete, and relatively high in economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a concrete additive and a preparation method thereof. Background technique [0002] In recent years, with the progress of society and the development of economy, various buildings and construction projects have sprung up. These buildings and construction projects are the crystallization of the development of the times and a symbol of a city. It records the history and Change is the hallmark of modern civilization. Behind these buildings and construction projects that represent modern cities, the use of construction engineering materials is inseparable. Construction engineering materials are a necessary condition to ensure the quality of construction projects and the safety of buildings. Concrete, as an indispensable construction material in the construction process of modern construction engineering, plays a vital role in ensuring the safety and quality of buildings. ...
