Low-temperature steam-curing-free concrete and preparation method thereof
The invention discloses low-temperature steam-curing-free concrete and a preparation method thereof.The preparation method comprises the steps that at different construction environment temperatures, quicklime powder of different proportions is mixed into a concrete semi-finished product, meanwhile, carbon dioxide gas is introduced into a mixture of the concrete semi-finished product and the quicklime powder, and after fusion and stirring, a carbonized low-temperature concrete finished product is prepared. According to the present invention, the concrete having characteristics of rapid setting and early strength can be prepared, the concrete can be used in different low-temperature construction environments, the preparation steps are simple, the site construction difficulty is low, the carbon dioxide can be recycled, and the environmental protection is easily achieved.
本发明公开了一种低温免蒸养混凝土及其制备方法，通过在不同的施工环境温度下，在混凝土半成品中掺入不同比例的生石灰粉末，同时向混凝土半成品和生石灰粉末的混合物中通入二氧化碳气体，融合搅拌后，制成碳化低温混凝土成品。本发明能够制备出具有快速凝结和早强性能的混凝土，能够在不同的低温施工环境下使用，而且制备步骤简单，现场施工难度低，同时能够回收利用二氧化碳，有利于环境保护。
