Problems solved by technology

After the 1990s, with the development of high-performance concrete, the problem of concrete cracks has not been reduced, on the contrary, it has become more and more prominent than before. Although some projects have adopted expansion agents, paid attention to maintenance, and increased the amount of cement, etc., the results have been very good. micro

Abstract

The invention discloses a light-silicon fiber crack-proof reinforcer of concrete in the making domain of organic and inorganic material, which comprises the following parts: anhydrous calcium sulphoaluminate, raw alunite, ripe alunite, anhydrite, naphthalene-system high-effective dehydragent, grammite, polypropylene fibre, sodium lignosulfonate and coal ash. The invention confers high-density and superior constructing property for concrete with modified boundary structure and high-concrete compactness, strength and durability, which improves stretching resistance greatly.

Description

Technical field [0001] The invention belongs to a light silicon fiber crack-resisting reinforcing agent prepared by using inorganic materials and organic materials as effective components of concrete. Background technique [0002] Now, with the increasing variety of concrete products, the increasing complexity and large-scale development of structures, many super-large special concrete structures have emerged. These new concrete products and special projects rely only on existing vibration, pressure, vacuum, etc. The technology can no longer meet the requirements of construction, and there is an urgent need to provide high-performance concrete with different properties for concrete preparation and construction. The cracking and leakage of concrete is a technical problem that has not been well solved for a long time, and the destruction or even collapse of the concrete structure starts from the crack propagation. Harmful cracks not only affect the appearance, but also reduce the s...
