Maintenance method for manufacturing foam concrete member

Abstract

The invention discloses a maintenance method for manufacturing a foam concrete member, which adopts a thermal insulation mold and is characterized in that the initial setting time and the final setting time temperature of cement in foam concrete slurry in the thermal insulation mold are controlled; wherein the temperature t of the foam concrete slurry and the member formed by the foam concrete slurry is controlled to be 30 DEG C<=t<70 DEG C within the time period from 0.5 hour before the final setting time to 5 hours after the final setting time. The method is suitable for manufacturing foam concrete members which are high in using amount of cement and other active materials, small in coarse and fine aggregate content and suitable for temperature rise, has the advantages of being easy to operate, low in manufacturing cost, small in investment, reliable in quality, low in energy consumption, easy to popularize and the like, and provides powerful technical support for building energy conservation and fabricated buildings.

Description

technical field [0001] The invention relates to a maintenance method for making foam concrete components, in particular to a maintenance method for self-heating concrete components. Background technique [0002] Concrete components, especially foam concrete components, often require steam curing or autoclaving curing to improve the mechanical performance indicators of the components. Steam curing requires large investment, energy consumption, and high cost, which does not meet the current building energy-saving requirements. A patent with the patent number "2017100094981" and "a method for manufacturing high-strength foam concrete products" is disclosed in the prior art. The manufacturing method is as follows: Step 1: making foam concrete slurry; Mold maintenance; step 3, demoulding, watering and moisturizing maintenance, and the finished product step. The main technical characteristics are as follows: ①In the production process, the temperature of the foamed concrete slurry...

Problems solved by technology

This kind of production method has a higher curing temperature, which can easily melt the insulation pipe in the board, and the finished product is also prone to cracks due to dehydration. Not only that, in order to increase the curing temperature, it is necessary to increase the mold foam. The temperature of the concrete slurry needs to be increased, which is difficult in the cold weather in the north, and the energy consumption is also high
