Problems solved by technology

However, this method can only achieve good results in ordinary room temperature environments, and is not suitable for concrete that requires heat resistance. The reason is that the surface of the concrete changes rapidly due to the temperature difference under the action of high temperature, resulting in cracks on the surface of the concrete.

Embodiment Construction

[0013] Hereinafter, the method for enhancing the wear resistance of concrete in a thermal environment of the present invention will be described in detail with reference to exemplary embodiments.

[0014] In hot environment concrete engineering, there are often high requirements for the wear resistance, impact resistance, and heat resistance of the concrete surface. The conventional wear-resistant ground method can no longer meet the use requirements, because the surface of the concrete in a high temperature environment Due to the sharp change of temperature difference, concrete is prone to cracking.

[0015] After research, according to the requirements of the use environment for concrete wear resistance, impact resistance and heat resistance, and without changing the original design strength of the concrete, the inventor evenly spread steel fibers on the surface of the concrete and made it Form a whole, so as to improve the wear resistance and impact resistance of concrete, ...

Abstract

The invention provides a method enhancing abrasive resistance of concrete in thermal environments. The method enhancing abrasive resistance of concrete in thermal environments comprises spreading steel fibers on a concrete face layer about to solidify, and then performing floating and grinding scattering process to form crisscross steel fibers on the concrete face layer. The method enhancing abrasive resistance of concrete in thermal environments has the advantages of being capable of effectively restraining cracking of face layer concrete and capable of improving straining resisting capability, stripping resisting capability, breaking resisting capability and mechanical shock resisting capability. Besides, the method further has the advantages of being fast in construction and easy to operate, and constructed concrete is smooth in surface, corrosion-free, crack-free and abrasion resisting.

Description

technical field [0001] The invention relates to the technical field of concrete and its construction, and more specifically relates to a method capable of enhancing the wear resistance, impact resistance and crack resistance of concrete in a thermal environment. Background technique [0002] Usually, the common practice of wear-resistant floors is to spread wear-resistant granular materials on the concrete surface, such as emery sand wear-resistant floors, iron filings wear-resistant floors and non-metal hardener wear-resistant floors. However, this method can only achieve good results in ordinary room temperature environments, and it is not suitable for concrete that requires heat resistance. The reason is that the surface of concrete under high temperature changes rapidly due to temperature differences, resulting in cracks on the surface of the concrete. Contents of the invention [0003] It is an object of the present invention to solve at least one of the above-mention...
