Abstract

The invention is suitable for the field of building materials and provides an anti-cracking and anti-seepage agent for concrete. The anti-cracking and anti-seepage agent comprises the following components in parts by weight: 10-70 parts of flyash, 10-50 parts of fluorgypsum and 10-70 parts of phosphorus slag. The anti-cracking and anti-seepage agent for concrete can reduce hydration heat, compensate for concrete shrinkage, improve the concrete strength and prevent cracking, seepage and other phenomena of concrete, thus improving the stability and durability of concrete.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an anti-crack and anti-seepage agent for concrete. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary times and is widely used in all aspects of construction. However, due to the widespread shrinkage of concrete, especially large-volume concrete and high-strength concrete, concrete cracks are caused, and the performance of concrete strength, anti-seepage, and corrosion resistance is reduced. At present, the obvious defects of using expansion agent as shrinkage compensation concrete material in the market are: the heat of hydration of concrete is high, the shrinkage and deformation of concrete are large, concrete cracking and leakage are common, and at the same time, the strength of concrete is greatly reduced. . Moreover, most of the domestic various types of concrete shrinkage compensating materials, such as expansi...
