Concrete anti-seismic impact-resistant anti-cracking agent

Abstract

The invention discloses concrete anti-seismic impact-resistant anti-cracking agent. The anti-cracking agent is a mixture of the following materials in parts by weight: 13-17 parts of industrial aluminum sulfate, 2-5 parts of high-strength imitated steel wire fiber, 0.1-0.4 part of lauryl sodium sulfate, 7-13 parts of silica fume, 34.5-45 parts of anhydrite, 23-30 parts of sulfoaluminate clinker and 3-7 parts of active excitant; during a concrete preparation process, the weight of cementing material doped in the concrete is 6%-8%, so that the shrinkage of the concrete is compensated at a plastic stage and each stage after the hardening stage, and therefore, the anti-bending anti-folding capacity of the concrete can be increased, the anti-seismic impact-resistant performances and anti-cracking seepage-proofing performances of the concrete are improved and the durability of the structure is greatly strengthened.

Description

technical field [0001] The invention relates to an anti-cracking agent, in particular to an anti-shock, anti-shock and anti-cracking agent for concrete. Background technique [0002] With the acceleration of urbanization in our country, the development of urban construction and the increase of population density, the harm of earthquakes to human beings has become more and more serious. It is of great practical significance to do a good job in the prediction of building earthquake damage. [0003] Earthquakes are inevitable as a natural phenomenon. According to statistics, from 2007 to 2009, there were as many as 54 earthquakes with a magnitude of 7.0 or above in the world, of which 35% were earthquakes with a magnitude of 7.5 or above, causing direct economic losses. tens of billions of dollars. my country has a vast territory, and there are countless cities built in earthquake zones and earthquake-prone areas. The 2008 Wenchuan Earthquake in Sichuan and the 2010 Qinghai Y...
