Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an anti-cracking and anti-seepage ready-mixed concrete and a preparation process thereof. Background technique [0002] Ready-mixed concrete is the concrete that is centrally mixed and transported to construction sites in factories or workshops. As the most widely used building material in civil engineering today, ready-mixed concrete is increasingly used in important structural parts such as super high-rise buildings, water conservancy dams, nuclear power plants, and underground buildings. [0003] Ready-mixed concrete is an indispensable material in urban construction, road and bridge construction, and water conservancy projects. It not only plays the role of structural support, but also requires concrete to have good impermeability and anti-cracking performance in some special scenarios. In order to achieve excellent anti-cracking and anti-seepage performance of co...
