Problems solved by technology

[0002] At present, after the completion and operation of many expressways, due to the change of climate and ambient temperature, the pavement will have different degrees of high and low temperature diseases, which will greatly shorten the service life of the pavement, causing many expressways to enter the overhaul or renovation period ahead of time, which not only causes a lot of economic losses, but also a great consumption of non-renewable resources

Abstract

The invention discloses a concrete capable of controlling temperature, which is prepared from the following raw materials in parts by weight: 70-80 parts of binder, 10-15 parts of chopped carbon fiber, 0.5-0.8 part of copper-plated steel fiber, 0.8-1.0 part of rubber powder, 0.1-0.3 part of water reducing agent and 0.05-0.10 part of defoaming agent. The preparation method comprises the following steps: adding water into the raw materials and aggregate, mixing uniformly, pouring and curing. The concrete capable of controlling temperature has the self-temperature-control properties, has obvious cooling effect under high-temperature conditions, has the heat storage function under low-temperature conditions, is suitable for highway construction, and can effectively prolong the service life of the highway.

Description

technical field [0001] The invention belongs to the technical field of concrete materials, and in particular relates to a temperature-controllable concrete. Background technique [0002] At present, after the completion and operation of many expressways, due to the change of climate and ambient temperature, the pavement will have different degrees of high and low temperature diseases, which will greatly shorten the service life of the pavement, causing many expressways to enter the overhaul or renovation period ahead of time, which not only causes a lot of economic losses, but also a great consumption of non-renewable resources. Contents of the invention [0003] The purpose of the present invention is to provide a temperature-controllable concrete, which has self-temperature control performance, has a significant cooling effect under high temperature conditions, and has a heat storage function under low temperature conditions, which is suitable for expressway construction...
