Preparation method of carbon dioxide premixed cement-based composite material
The invention discloses a preparation method of a carbon dioxide premixed cement-based composite material. The method comprises the following steps: 1, introducing gas containing carbon dioxide into cement paste which is stirred in a closed state for 30-240 seconds; 2, when the fluidity of the cement paste is obviously reduced, water accounting for 1%-3% of the mass of the cement is added into the cement paste so as to restore the original fluidity of the cement paste. The method has the characteristics of improving the material strength, reducing the cement consumption, relieving the greenhouse effect and being high in economic benefit.
本发明公开了一种二氧化碳预拌水泥基复合材料的制备方法。包括以下步骤：步骤一：往密闭状态下正搅拌的水泥浆体中通入含二氧化碳的气体30s～240s；步骤二：当水泥浆体流动度明显降低时，向其中加入水泥质量1％～3％的水以恢复其原先的流动度。本发明具有提高材料强度，减少水泥用量，缓解温室效应和经济效益高的特点。
